2828
* A new configuration property with name `version-in-branch-pattern` has been introduced. This setting only applies on branches where the option `is-release-branch` is set to `true`. Please notice that the branch name needs to be defined after the version number by default (instead of `support/lts-2.0.0` please name the branch like `support/2.0.0-lts`).
2929
* The `is-release-branch` property of the `hotfix` branch setting has been changed from `false` to `true`. If present the hotfix number will be considered now by default.
3030
* In the GitHub and the Git Flow workflows the `label` property is by default set to an empty string on the `main` branch. This yields to a pre-release version on `main` with an empty tag. Instead of for instance `1.0.1+46` GitVersion generates the full semantic version `1.0.1-46` instead. This behavior can be changed to generate only stable versions (no pre-release version) with setting the label to `null` (Please keep in mind that the `label` property on root needs to be set to `null` as well, otherwise the fallback applies). This change is caused by issue #2347.
31+
* The `useBranchName` magic string has been removed. Instead use `{BranchName}` for `label`.
32+
* The `BranchPrefixToTrim` configuration property has been removed. `RegularExpression` is now used to capture named groups instead.
33+
* Default `RegularExpression` for feature branches is changed from `^features?[/-]` to `^features?[/-](?<BranchName>.+)` to support using `{BranchName}` out-of-the-box
34+
* Default `RegularExpression` for unknown branches is changed from `.*` to `(?<BranchName>.*)` to support using `{BranchName}` out-of-the-box
