Fix: When using the new self.folders.source (at layout(self) method) the sources (from export, export_sources and scm) are copied to the base source folder and not to the self.folders.source that is intended to describe where the sources are after fetching them. #9043 . Docs here
BugFix: Do not quote all values and allow integer and macro referencing in MSBuildToolchain.preprocessor_definitions #9056
Bugfix: The new generators like CMakeDeps and CMakeToolchain`write the generated files defaulting to the `install folder if no self.folders.generators is specified in the layout() method. #9050

Note

Breaking changes

This is an important release towards stabilizing conan and moving out of beta. Some breaking changes have been done, but mostly to command line arguments, so they should be easy to fix. Package recipes or existing packages shouldn't break. Please update, it is very important to ease the transition of future stable releases. Do not hesitate to ask questions, or for help if you need it. This is a possibly not complete list of things to take into account:

The command :command:`conan install` doesn't accept cwd anymore, to change the directory where the generator files are written, use the :command:`--install-folder` parameter.
The command :command:`conan install` doesn't accept :command:`--all` anymore. Use :command:`conan download <ref>` instead.
The command :command:`conan build` now requires the path to the conanfile.py (optional before)
The command :command:`conan package` not longer re-package a package in the local cache, now it only operates in a user local folder. The recommended way to re-package a package is using :command:`conan build` and then :command:`conan export-pkg`.
Removed :command:`conan package_files` in favor of a new command :command:`conan export-pkg`. It requires a local recipe with a package() method.
The command :command:`conan source` no longer operates in the local cache. now it only operates in a user local folder. If you used :command:`conan source` with a reference to workaround the concurrency, now it natively supported, you can remove the command call and trust concurrent install processes.
The command :command:`conan imports` doesn't accept -d, --dest anymore, use :command:`--imports-folder` parameter instead.
If you specify a profile in a conan command, like conan create or conan install the base profile ~/.conan/profiles/default won't be applied. Use explicit include to keep the old behavior.

0.27.0 (20-September-2017)

Fix: "-" symbol available again in usernames.
Fix: Added future requirement to solve an error with pyinstaller generating the Windows installer.

0.22.0 (18-April-2017)

Feature: [build_requires] can now be declared in profiles and apply them to build packages. Those requirements are only installed if the package is required to build from sources, and do not affect its package ID hash, and it is not necessary to define them in the package recipe. Ideal for testing libraries, cross compiling toolchains (like Android), development tools, etc.
Feature: Much improved support for cross-building. Support for cross-building to Android provided, with toolchains installable via build_requires.
Feature: New package_files command, that is able to create binary packages directly from user files, without needing to define build() or package() methods in the the recipes.

Feature: Improved CMake helper, with test() method, automatic setting of BUILD_SHARED_LIBS, better management of variables, support for parallel compilation in MSVC (via /MP)
Feature: new tools.msvc_build_command() helper that both sets the Visual vcvars and calls Visual to build the solution. Also vcvars_command is improved to return non-empty string even if vcvars is set, for easier concatenation.
Feature: Added package recipe linter, warning for potential errors and also about Python 3 incompatibilities when running from Python 2. Enabled by default can be opt-out.
Feature: Improvements in HTML output of :command:`conan info --graph`.
Feature: allow custom path to bash, as configuration and environment variable.
Fix: Not issuing an unused variable warning in CMake for the CONAN_EXPORTED variable

Fix: local :command:`conan source`` command (working in user folder) now properly executes the equivalent of exports functionality
Fix: Setting command line arguments to cmake command as CMake flags, while using the TARGETS approach. Otherwise, arch flags like -m32 -m64 for gcc were not applied.
BugFix: fixed :command:`conan imports` destination folder issue.
BugFix: Allowing environment variables with spaces
BugFix: fix for CMake with targets usage of multiple flags.
BugFix: Fixed crash of cmake_multi generator for "multi-config" packages.

0.20.3 (06-March-2017)

Fix: Added opt-out for CMAKE_SYSTEM_NAME automatically added when cross-building, causing users providing their own cross-build to fail
BugFix: Corrected usage of CONAN_CFLAGS instead of CONAN_C_FLAGS in cmake targets

Fix: Added missing commit for CMake new helpers

0.20.0 (27-February-2017)

NOTE: It is important that if you upgrade to this version, all the clients connected to the same remote, should upgrade too. Packages created with conan>=0.20.0 might not be usable with conan older conan clients.

Feature: Largely improved management of environment variables, declaration in package_info(), definition in profiles, in command line, per package, propagation to consumers.
Feature: New build helpers AutotoolsBuildEnvironment, VisualStudioBuildEnvironment, which deprecate ConfigureEnvironment, with much better usage of environment variables
Feature: New virtualbuildenv generator that will generate a composable environment with build information from installed dependencies.
Feature: New build_id() recipe method that allows to define logic to build once, and package multiple times without building. E.g.: build once both debug and release artifacts, then package separately.
Feature: Multi-config packages. Now packages can provide multi-configuration packages, like both debug/release artifacts in the same package, with self.cpp_info.debug.libs = [...] syntax. Not restricted to debug/release, can be used for other purposes.
Feature: new :command:`conan config` command to manage, edit, display conan.conf entries
Feature: :ref:`Improvements<cmake_reference>` to CMake build helper, now it has configure() and build() methods for common operations.

Bug fix: crashes when not supported characters were dumped to terminal by logger
Bug fix: wrong executable path in Visual Studio generator

0.19.3 (27-February-2017)

Fix: backward compatibility for new environment variables. New features to be introduced in 0.20 will produce that conaninfo.txt will not be correctly parsed, and then package would be "missing". This will happen for packages created with 0.20, and consumed with older than 0.19.3

NOTE: It is important that you upgrade at least to this version if you are using remotes with packages that might be created with latest conan releases (like conan.io).

0.19.2 (15-February-2017)

Bug fix: Fixed bug with remotes behind proxies
Bug fix: Fixed bug with exports_sources feature and nested folders

0.19.1 (02-February-2017)

Feature: new configurable tracer able to create structured logs of conan actions: commands, API calls, etc
Feature: new logger for self.run actions, able to log information from builds and other commands to files, that can afterwards be packaged together with the binaries.
Feature: support for Solaris SunOS
Feature: Version helper improved with patch, pre, build capabilities to handle 1.3.4-alpha2+build1 versions
Feature: compress level of tgz is now configurable via CONAN_COMPRESSION_LEVEL environment variable, default 9. Reducing it can lead to faster compression times, at the expense of slightly bigger archives
Feature: Add powershell support for virtualenv generator in Windows
Feature: Improved system_requirements() raising errors when failing, retrying if not successful, being able to execute in user space for local recipes
Feature: new cmake helper macro conan_target_link_libraries().
Feature: new cmake CONAN_EXPORTED variable, can be used in CMakeLists.txt to differentiate building in the local conan cache as package and building in user space
Fix: improving the caching of options from :command:`conan install` in conaninfo.txt and precedence.
Fix: conan definition of cmake output dirs has been disabled for cmake_multi generator
Fix: imports() now uses environment variables at "conan install" (but not at "conan imports" yet)
Fix: conan_info() method has been renamed to package_id(). Backward compatibility is maintained, but it is strongly encouraged to use the new name.
Fix: conan_find_libraries now use the NO_CMAKE_FIND_ROOT_PATH parameter for avoiding issue while cross-compiling
Fix: disallowing duplicate URLs in remotes, better error management
Fix: improved error message for wildcard uploads not matching any package

Bugfix: fixed management of VerifySSL parameter for remotes
Bugfix: fixed misdetection of compiler version in conanbuildinfo.cmake for apple-clang
Bugfix: fixed trailing slash in remotes URLs producing crashes
Refactor: A big refactor has been do to options. Nested options are no longer supported, and option.suboption will be managed as a single string option.

This has been a huge release with contributors of 11 developers. Thanks very much to all of them!

0.16.1 (05-December-2016)

Solved bug with test_package with arguments, like scopes.

0.16.0 (19-November-2016)

Upgrade: The build=outdated`` feature had a change in the hash computation, it might report outdated binaries from recipes. You can re-build the binaries or ignore it (if you haven't changed your recipes without re-generating binaries)

Feature: version ranges. Conan now supports defining requirements with version range expressions like Pkg/[>1.2,<1.9||1.0.1]@user/channel. Check the :ref:`version ranges reference <version_ranges>` for details
Feature: decoupled imports from normal install. Now :command:`conan install --no-imports` skips the imports section.
Feature: new :command:`conan imports` command that will execute the imports section without running install
Feature: overriding settings per package. Now it is possible to specify individual settings for each package. This can be specified both in the command line and in profiles
Feature: environment variables definition in the command line, global and per package. This allows to define specific environment variables as the compiler (CC, CXX) for a specific package. These environment variables can also be defined in profiles. Check :ref:`profiles reference <profiles>`
Feature: Now conan files copies handle symlinks, so files are not duplicated. This will save some space and improve download speed in some large packages. To enable it, use self.copy(..., links=True)
Fix: Enabling correct use of MSYS in Windows, by using the Windows C:/... path instead of the MSYS ones
Fix: Several fixes in :command:`conan search`, both local and in remotes
Fix: Manifests line endings and order fix, and hash computation fixed (it had wrong ordering)

Improved and completed documentation

0.15.0 (08-November-2016)

Upgrade: If you were using the short_paths feature in Windows for packages with long paths, please reset your local cache. You could manually remove packages or just run :command:`conan remove "*"`

Feature: New build=outdated`` functionality, that allows to build the binary packages for those dependencies whose recipe has been changed, or if the binary is not existing. Each binary package stores a hash of the recipe to know if they have to be regenerated (are outdated). This information is also provided in the :command:`conan search <ref>`` command. Useful for package creators and CI.
Feature: Extended the short_paths feature for Windows path limit to the package folder, so package with very long paths, typically in headers in nested folder hierarchies are supported.
Feature: New tool.build_sln_command() helper to build() Microsoft Visual Studio solution (.sln) projects
Feature: Extended the source and package command, so together with build they can be fully executed in a user folder, as a convenience for package creation and testing.
Feature: Extending the scope of tools.pythonpath to work in local commands too
Improved the parsing of profiles and better error messages
Not adding -s compiler flag for clang, as it doesn't use it.
Automatic generation of conanenv.txt in local cache, warnings if using local commands and no conanbuildinfo.txt and no conanenv.txt are present to cache the information form install
Fix: Fixed bug when using empty initial requirements (requires = "")
Fix: Added glob hidden import to pyinstaller
Fix: Fixed minor bugs with short_paths as local search not listing packages
Fix: Fixed problem with virtual envs in Windows with paths separator (using / instead of )
Fix: Fixed parsing of conanbuildinfo.txt, so the root folder for each dependency is available in local commands too
Fix: Fixed bug in test_package with the test project using the requirements() method.

0.14.1 (20-October-2016)

Fixed bug with short_paths feature in windows.
Improved error messages for non-valid profile test files.
Remove downloaded tgz package files from remotes after decompress them.
Fixes bug with install --all and short_paths

0.14.0 (20-October-2016)

Feature: Added profiles, as user predefined settings and environment variables (as CC and CXX for compiler paths). They are stored in files in the conan cache, so they can be easily edited, added, and shared. Use them with :command:`conan install --profile=name`
Feature: short_paths feature for Windows now also handle long paths for the final package, in case that a user library has a very long final name, with nested subfolders.
Feature: Added tools.cpu_count() as a helper to retrieve the number of cores, so it can be used in concurrent builds
Feature: Detects cycles in the dependency graph, and raise error instead of exhausting recursion limits
Feature: Conan learned the werror`` option that will raise error and stop installation under some cases treated as warnings otherwise: Duplicated dependencies, or dependencies conflicts
Feature: New env generator that generates a text file with the environment variables defined by dependencies, so it can be stored. Such file is parsed by :command:`conan build` to be able to use such environment variables for self.deps_env_info too, in the same way it uses the txt generator to load variables for self.deps_cpp_info.
Fix: Do not print progress bars when output is a file
Fix: Improved the local conan search, using options too in the query :command:`conan search -q option=value`
Fix: Boto dependency updated to 2.43.0 (necessary for ArchLinux)
Fix: Simplified the :command:`conan package` command, removing unused and confusing options, and more informative messages about errors and utility of this command.
Fix: More fixes and improvements on ConfigureEnvironment, mainly for Windows
Fix: Conan now does not generate a conanbuildinfo.txt file when doing :command:`conan install <PkgRef>`.
Bug fix: Files of a package recipe are "touched" to update their timestamps to current time when retrieved, otherwise some build systems as Ninja can have problems with them.
Bug fix: qmake generator now uses quotes to handle paths with spaces
Bug fix: Fixed OSInfo to return the short distro name instead of the long one.
Bug fix: fixed transitivity of private dependencies

0.13.3 (13-October-2016)

This minor solves some problems with ConfigureEnvironment, mainly for Windows, but also fixes other things:

Fixed concatenation problems in Windows for several environment variables. Fixed problems with path with spaces
A batch file is created in Windows to be called, as if defined structures doesn't seem to work in the command line.
The vcvars_command from tools now checks the Visual Studio environment variable, if it is already set, it will check it with the current project settings, throwing an error if not matching, returning an empty command if matches.
Added a compile_flags property to ConfigureEnvironment, to be passed in the command line to the compiler, but not as environment variables
Added defines to environment for nix systems, it was not being handled before
Added new tests, compiling simple projects and diamond dependencies with cmake, cl (msvc), gcc (gcc in linux, mingw in win) and clang (OSX), for a better coverage of the ConfigureEnvironment functionality.
Fixed wrong CPP_INCLUDE_PATH, it is now CPLUS_INCLUDE_PATH

0.13.0 (03-October-2016)

IMPORTANT UPGRADE ISSUE: There was a small error in the computation of binary packages IDs, that has been addressed by conan 0.13. It affects to third level (and higher) binary packages, i.e. A and B in A->B->C->D, which binaries must be regenerated for the new hashes. If you don't plan to provide support for older conan releases (<=0.12), which would be reasonable, you should remove all binaries first (:command:`conan remove -p`, works both locally and remotely), then re-build your binaries.

Features:

Streaming from/to disk for all uploads/downloads. Previously, this was done for memory, but conan started to have issues for huge packages (>many hundreds MBs), that sometimes could be alleviated using Python 64 bits distros. This issues should be alleviated now
New security system that allows capturing and checking the package recipes and binaries manifests into user folders (project or any other folder). That ensures that packages cannot be replaced, hacked, forged, changed or wrongly edited, either locally or in any remote server, without notice.
Possible to handle and reuse python code in recipes. Actually, conan can be used as a package manager for python, by adding the package path to env_info.PYTHONPATH. Useful if you want to reuse common python code between different package recipes.
Avoiding re-compress the tgz for packages after uploads if it didn't change.
New command :command:`conan source` that executes the source() method of a given conanfile. Very useful for CI, if desired to run in parallel the construction of different binaries.
New propagation of cpp_info, so it now allows for capturing binary packages libraries with new collect_libs() helper, and access to created binaries to compute the package_info() in general.
Command test_package now allows the update`` option, to automatically update dependencies.
Added new architectures for ppc64le and detection for AArch64
New methods for defining requires effect over binary packages ID (hash) in conan_info()
Many bugs fixes: error in tools.download with python 3, restore correct prompt in virtualenvs, bug if removing an option in config_options(), setup.py bug...

This release has contributions from @tru, @raulbocanegra, @tivek, @mathieu, and the feedback of many other conan users, thanks very much to all of them!

0.12.0 (13-September-2016)

Major changes to search api and commands. Decoupled the search of package recipes, from the search of binary packages.
Fixed bug that didn't allow to export or upload packages with settings restrictions if the restrictions didn't match the host settings
Allowing disabling color output with CONAN_COLOR_DISPLAY=0 environment variable, or to configure color schema for light console backgrounds with CONAN_COLOR_DARK=1 environment variable
Imports can use absolute paths, and files copied from local conan cache to those paths will not be removed when :command:`conan install`. Can be used as a way to install machine-wise things (outside conan local cache)
More robust handling of failing transfers (network disconnect), and inconsistent status after such
Large internal refactor for storage managers. Improved implementations and decoupling between server and client
Fixed slow :command:`conan remove` for caches with many packages due to slow deletion of empty folders
Always allowing explicit options scopes, - o Package:option=value as well as the implicit -o option=value for current Package, for consistency
Fixed some bugs in client-server auth process.
Allow to extract .tar files in tools.unzip()
Some helpers for conan_info(), as self.info.requires.clear() and removal of settings and options

0.11.1 (31-August-2016)

New error reporting for failures in conanfiles, including line number and offending line, much easier for package creators
Removed message requesting to create an account in conan.io for other remotes
Removed localhost:9300 remote that was added by default mostly for demo purposes. Clarified in docs.
Fixed usernames case-sensitivity in conan_server, due to ConfigParser it was forcing lowercase
Handling unicode characters in remote responses, fixed crash
Added new compilers gcc 6.2, clang 8.0 to the default settings.yml
Bumped cryptography, boto and other conan dependencies, mostly for ArchLinux compatibility and new OSX security changes

0.11.0 (3-August-2016)

New solution for the path length limit in Windows, more robust and complete. Package conanfile.py just have to declare an attribute short_paths=True and everything will be managed. The old approach is deprecated and totally removed, so no shorts_paths.conf file is necessary. It should fix also the issues with uploads/retrievals.
New virtualenv generator that generates activate and deactivate scripts that set environment variables in the current shell. It is very useful, for example to install tools (like CMake, MinGW) with conan packages, so multiple versions can be installed in the same machine, and switch between them just by activating such virtual environments. Packages for MinGW and CMake are already available as a demo
ConfigureEnvironment takes into account environment variables, defined in packages in new env_info, which is similar to cpp_info but for environment information (like paths).
New per-package build_policy, which can be set to always or missing, so it is not necessary to create packages or specify the build`` parameter in command line. Useful for example in header only libraries or to create packages that always get the latest code from a branch in a github repository.
Command :command:`conan test_package`` now executes by default a :command:`conan export` with smarter package reference deduction. It is introduced as opt-out behavior.
Conan :command`export` command avoids copying test_package/build temporary files in case of export=*
Now, package_info() allows absolute paths in includedir, libdirs and bindirs, so wrapper packages can be defined that use system or manually installed libraries.
LDFLAGS in ConfigureEnvironment management of OSX frameworks.
Options allow the ANY value, so such option would accept any value. For example a commit of a git repository, useful to create packages that can build any specific commit of a git repo.
Added gcc 5.4 to the default settings, as well as MinGW options (Exceptions, threads...)
Command :command:`conan info` learned a new option to output the packages from a project dependency tree that should be rebuilt in case of a modification of a certain package. It outputs a machine readable ordered list of packages to be built in that order. Useful for CI systems.
Better management of incomplete, dirty or failed source directories (e.g. in case of a user interrupting with Ctrl+C a git clone inside the source() method.
Added tools for easier detection of different OS versions and distributions, as well as command wrappers to install system packages (apt, yum). They use sudo via a new environment variable CONAN_SYSREQUIRES_SUDO, so using sudo is opt-in/out, for users with different sudo needs. Useful for system_requirements()
Deprecated the config() method (still works, for backwards compatibility), but has been replaced by a config_options() to modify options based on settings, and a configure() method for most use cases. This removes a nasty behavior of having the config() method called twice with side effects.
Now, running a :command:`conan install MyLib/0.1@user/channel` to directly install packages without any consuming project, is also able to generate files with the -g option. Useful for installing tool packages (MinGW, CMake) and generate virtualenvs.
Many small fixes and improvements: detect compiler bug in Py3, search was crashing for remotes, conan new failed if the package name had a dash, etc.
Improved some internal duplications of code, refactored many tests.

This has been a big release. Practically 100% of the released features are thanks to active users feedback and contributions. Thanks very much again to all of them!

0.10.0 (29-June-2016)

conan new command, that creates conan package conanfile.py templates, with a test_package package test (-t option), also for header only packages (-i option)
Definition of scopes. There is a default dev scope for the user project, but any other scope (test, profile...) can be defined and used in packages. They can be used to fire extra processes (as running tests), but they do not affect the package binaries, and are not included in the package IDs (hash).
Definition of dev_requires. Those are requirements that are only retrieved when the package is in dev scope, otherwise they are not. They do not affect the binary packages. Typical use cases would be test libraries or build scripts.
Allow shorter paths for specific packages, which can be necessary to build packages with very long path names (e.g. Qt) in Windows.
Support for bzip2 and gzip decompression in tools
Added package_folder attribute to conanfile, so the package() method can for example call cmake install to create the package.
Added CONAN_CMAKE_GENERATOR environment variable that allows to override the CMake default generator. That can be useful to build with Ninja instead of the default Unix Makefiles
Improved ConfigureEnvironment with include paths in CFLAGS and CPPFLAGS, and fixed bug.
New :command:`conan user --clean` option, to completely remove all user data for all remotes.
Allowed to raise Exceptions in config() method, so it is easier for package creators to raise under non-supported configurations
Fixed many small bugs and other small improvements

As always, thanks very much to all contributors and users providing feedback.

0.9.2 (11-May-2016)

Fixed download bug that made it specially slow to download, even crash. Thanks to github @melmdk for fixing it.
Fixed cmake check of CLang, it was being skipped
Improved performance. Check for updates has been removed from install, made it opt-in in :command:`conan info` command, as it was very slow, seriously affecting performance of large projects.
Improved internal representation of graph, also improves performance for large projects.
Fixed bug in :command:`conan install --update`.

0.9 (3-May-2016)

Python 3 "experimental" support. Now the main conan codebase is Python 2 and 3 compatible. Python 2 still the reference platform, Python 3 stable support in next releases.
Create and share your own custom generators for any build system or tool. With "generator packages", you can write a generator just as any other package, upload it, modify and version it, etc. Require them by reference, as any other package, and pull it into your projects dynamically.
Premake4 initial experimental support via a generator package.
Very large re-write of the documentation. New "creating packages" sections with in-source and out-source explicit examples. Please read it! :)
Improved :command:`conan test`. Renamed test to test_package both for the command and the folder, but backwards compatibility remains. Custom folder name also possible. Adapted test layout might require minor changes to your package test, automatic warnings added for your convenience.
Upgraded pyinstaller to generate binary OS installers from 2.X to 3.1
:command:`conan search` now has command line options:, less verbose, verbose, extra verbose
Added variable with full list of dependencies in conanbuildinfo.cmake
Several minor bugfixes (check github issues)
Improved :command:`conan user` to manage user login to multiple remotes

0.8.4 (28-Mar-2016)

Fixed linker problems with the new apple-clang 7.3 due to libraries with no timestamp set.
Added apple-clang 7.3 to default settings
Fixed default libcxx for apple-clang in auto detection of base conan.conf

0.8 (15-Mar-2016)

New conan remote command to manage remotes. Redesigned remotes architecture, now allows to work with several remotes in a more consistent, powerful and "git-like" way. New remotes registry keeps track of the remote of every installed package, and this information is shown in :command:`conan info` command too. Also, it keeps different user logins for different remotes, to improve support in corporate environments running in-house servers.
New update functionality. Now it is possible to :command:`conan install --update` to update packages that became obsolete because new ones were uploaded to the corresponding remote. Conan commands as install and info show information about the status of the local packages compared with the remote ones. In this way, using latest versions during development is much more natural.
Added new compiler.libcxx setting in order to support the different c++ standard libraries. It can take libstdc++, libstdc++11 or libc++ values to take into account different standard libraries for modern gcc and clang compilers. It is also possible to remove not needed settings, like this one in pure C projects, with the new syntax: del self.settings.compiler.libcxx
Conan virtual environment: Define a custom conan directory with CONAN_USER_HOME env variable, and have a per project or per workspace storage for your dependencies. So you can isolate your dependencies and even bundle them within your project, by just setting the CONAN_USER_HOME variable to your <project>/deps folder, for example. This also improves support for continuous integration CI systems, in which many builds from different users could be run in parallel.
Better conanfile download method. More stable and now checks (opt-out) the ssl certificates.
Lots of improvements: Increased library name length limit, Improved and cleaner output messages.
Fixed several minor bugs: removing empty folders, case sensitive exports, arm settings detection.
Introduced the concept of "package recipe" that refers to conanfile.py and exported files.
Improved settings display in web, with new "copy install command to clipboard" to assist in installing packages discovered in web.
The macOS installer, problematic with latest macOS releases, has been deprecated in favor of homebrew and pip install procedures.

0.7 (5-Feb-2016)

Custom conanfile names are allowed for developing. With file`` option you can define the file you want to use, allowing for .conaninfo.txt or having multiple conanfile_dev.py, conanfile_test.py besides the standard conanfile.py which is used for sharing the package. Inheritance is allowed, e.g. conanfile_dev.py might extend/inherit from conanfile.py.
New :command:`conan copy` command that can be used to copy/rename packages, promote them between channels, forking other users packages.
New all`` and package`` options for :command:`conan install` that allows to download one, several, or all package configurations for a given reference.
Added patch() tool to easily patch sources if necessary.
New qmake and qbs generators
Upload of conanfile exported files is also tgz'd, allowing fast upload/downloads of full sources if desired, avoiding retrieval of sources from externals sources.
:command:`conan info` command improved showing info of current project too
Output of run() can be redirected to buffer string for processing, or even removed.
Added proxy configuration to conan.conf for users behinds proxies.
Large improvements in commands output, prefixed with package reference, and much clear.
Updated settings for more versions of gcc and new arm architectures
Treat dependencies includes as SYSTEM in cmake, so no warnings are raised
Deleting source folder after :command:`conan export` so no manual removal is needed
Normalizing to CRLF generated user files in Win
Better detection and checks for compilers as VS, apple-clang
Fixed CMAKE_SHARED_LINKER_FLAGS typo in cmake files
Large internal refactor in generators

0.6 (11-Jan-2016)

New cmake variables in cmake generator to make FindPackage work better thanks to the underlaying FindLibrary. Now many FindXXX.cmake work "as-is" and the package creator does not have to create a custom override, and consumers can use packages transparently with the originals FindXXX.cmakes
New "conan info" command that shows the full dependency graph and details (license, author, url, dependants, dependencies) for each dependency.
New environment helper with a ConfigureEnvironment class, that is able to translate conan information to autotools configure environment definition
Relative importing from conanfiles now is possible. So if you have common functionality between different packages, you can reuse those python files by importing them from the conanfile.py. Note that export="..." might be necessary, as packages as to be self-contained.
Added YouCompleteMe generator for vim auto-completion of dependencies.
New "conanfile_directory" property that points to the file in which the conanfile.py is located. This helps if using the conanfile.py "build" method to build your own project as a project, not a package, to be able to use any workflow, out-of-source builds, etc.
Many edits and improvements in help, docs, output messages for many commands.
All cmake syntax in modern lowercase
Fixed several minor bugs: gcc detection failure when gcc not installed, missing import, copying source->build failing when symlinks

0.5 (18-Dec-2015)

New cmake functionality allows package creators to provide cmake finders, so that package consumers can use their CMakeLists.txt with typical FindXXX.cmake files, without any change to them. CMake CONAN_CMAKE_MODULES_PATH added, so that package creators can provide any additional cmake scripts for consumers.
Now it is possible to generate out-of-source and multiple configuration installations for the same project, so you can switch between them without having to :command:`conan install` again. Check :ref:`the new workflows<workflows>`
New qmake generator (thanks @dragly)
Improved removal/deletion of folders with shutil.rmtree, so :command:`conan remove` commands and other processes requiring deletion of folders do not fail due to permissions and require manual deletion. This is an improvement, especially in Win.
Created pip package, so conan can be installed via: pip install conan
Released pyinstaller code for the creation of binaries from conan python source code. Distros package creators can create packages for the conan apps easily from those binaries.
Added md5, sha1, sha256 helpers in tools, so external downloads from conanfile.py files source() can be checked.
Added latest gcc versions to default settings.yml
Added CI support for conan development: travis-ci, appveyor
Improved human-readability for download progress, help messages.
Minor bug fixes
