+Creating a release
+==================
+
+This file contains instructions for maintainers on how to release new versions of podman-compose.
+
+Step 1: Initialize variables for subsequent steps
+-------------------------------------------------
+
+```
+export VERSION=1.2.3
+```
+
+Step 2: Release notes PR
+------------------------
+
+Open a new branch (e.g. `release`) and run the following:
+
+```
+./scripts/make_release_notes.sh $VERSION
+```
+
+This collects the release notes using the `towncrier` tool and then commits the result.
+This step is done as a PR so that CI can check for spelling errors and similar issues.
+
+Certain file names are not properly supported by the `towncrier` tool and it ignores them.
+Check `newsfragments` directory for any forgotten release notes
+
+Step 3: Merge the release notes PR
+----------------------------------
+
+Step 4: Perform actual release
+------------------------------
+
+Pull the merge commit created on the `main` branch during the step 2.
+Then run:
+
+```
+./scripts/make_release.sh
+```
+
+This will create release commit, tag and push everything.
+
+Step 5: Create a release on Github
+----------------------------------
+
+The release notes must be added manually by drafting a release on the GitHub UI at
+https://github.com/containers/podman-compose/releases.

+Version 1.3.0 (2025-01-07)
+==========================
+
+Bug fixes
+---------
+
+- Fixed support for de-facto alternative `Dockerfile` names (e.g. `Containerfile`)
+- Fixed a bug that caused attempts to create already existing pods multiple times.
+- Fixed compatibility with docker-compose in how symlinks to docker-compose.yml are handled.
+- Fixed freeze caused by too long log lines without a newline.
+- Fixed support for `network_mode: none`.
+- Improved error detection by rejecting service definitions that contain both `network_mode` and
+  `networks` keys, which is not allowed.
+
+
+Features
+--------
+
+- Added support for build labels.
+- Added support for "platform" property in the build command.
+- Added support for "ssh" property in the build command.
+- Added support for cache_from and cache_to fields in build section.
+- Added support for honoring the condition in the depends_on section of the service, if stated.
+- Added `x-podman.no_hosts` setting to pass `--no-hosts` to podman run
+- Added support for compatibility with docker compose for default network behavior when no network
+  defined in service. This is controlled via `default_net_behavior_compat` feature flag.
+- Added a way to get compatibility of default network names with docker compose.
+  This is selected by setting `default_net_name_compat: true` on `x-podman` global dictionary.
+- Added support for the `device_cgroup_rules` property in services.
+- Added support for removing networks in `podman-compose down`.
+- Added support for network scoped service aliases.
+- Added support for network level `mac_address` attribute.
+- Added ability to substitute variables with the environment of the service.
+
+Misc
+----
+
+- Declared compatibility with Python 3.13.
