Changelog

Sourced from dunamai's changelog.

v1.21.2 (2024-06-26)

• Fixed: Some timestamps could fail to parse on Python 3.5 and 3.6.

v1.21.1 (2024-05-03)

• Fixed: Distance was calculated inconsistently for Git when there were some tags and none matched the version pattern.

v1.21.0 (2024-04-29)

• Generally, when Dunamai can detect the VCS in use, but there's no version set yet, then Dunamai uses 0.0.0 as a fallback, unless strict mode is enabled. This is useful for new projects that do not yet have a release.

  However, if there were some tags and none matched the version pattern, then Dunamai would yield an error. That wouldn't be helpful for a new project with some non-version tag, and it could be incorrect for a monorepo with different tags for different packages.

  Now, Dunamai will use 0.0.0 in this case as well, unless strict mode is enabled.

• You can now specify a pattern prefix. For example, --pattern default --pattern-prefix some-package- would match tags like some-package-v1.2.3. This is useful if you just want a custom prefix without writing a whole pattern.

• Added --ignore-untracked option to control checking whether the repository is dirty.

v1.20.0 (2024-04-12)

• Updated Version.bump() to add a smart argument, which only bumps when distance != 0. This will also make Version.serialize() use pre-release formatting automatically, like calling Version.serialize(bump=True).

v1.19.2 (2024-02-16)

• Fixed an exception when a Git repository had a broken ref. Git would print a warning that Dunamai failed to parse.

v1.19.1 (2024-02-07)

• Relaxed Python bounds from ^3.5 to >=3.5 since Python does not follow Semantic Versioning.
• Fixed some git log commands that did not include -c log.showsignature=false. (Contributed by pdecat)

v1.19.0 (2023-10-04)

• Added a --path option to inspect a directory other than the current one. The Version.from_* methods now also take a path argument.
