feat: add support for configuring a commit specification (e.g. "conventional commits")

README.md

@@ -185,6 +185,29 @@ This job can be enabled by defining the `SEMREL_INFO_ON` variable:
 * `protected` to enable on protected references
 * `all` to enable on all Git references. :warning: Beware that this job requires the `GITLAB_TOKEN` variable so you must unprotect it (this will make privilege escalation possible from developer to maintainer).
 
+#### Semantic Release Commit Analyzer and Release Notes Configuration
+
+Semantic Release determines the semantic version, major.minor.patch, with the use of `@semantic-release/commit-analyzer` and `@semantic-release/release-notes-generator` `presets`. The [**default** preset is `angular`](https://github.com/semantic-release/semantic-release?tab=readme-ov-file#commit-message-format).
+The default _may_ lead to unexpected versioning or release notes, especially when not in an Angular project nor using the Angular standard.
+
+The commit message parser may be changed by defining the `commit-spec` / `SEMREL_COMMIT_SPEC` variable:
+
+| Input / Variable                            | Description | Default |
+| ------------------------------------------- | ----------- | ------- |
+| `commit-spec` / `SEMREL_COMMIT_SPEC` | commit specification `preset` (possible values: `angular`, `codemirror`, `ember`, `eslint`, `express`, `jquery`, `jshint`, `conventionalcommits` (`cc` short form supported)) | `angular` |
+
+**Conventional Commit Specification**
+
+The `preset` of `conventionalcommits` (or `cc`) is a good option for most users. The [specification is well defined and documented](https://www.conventionalcommits.org/en/v1.0.0/) and compatible with tools like [Husky](https://typicode.github.io/husky/) and [commitlint](https://commitlint.js.org/). Semantic Release has plans to make `conventionalcommits` the default in the future.
+
+**Commit Message Controls**
+
+The `commit-spec` / `SEMREL_COMMIT_SPEC` value installs the parser requirement for Semantic Release only. Adherence to a specification with commit message controls is not provided. Angular and Conventional Commits are widely supported by commitlint and [commitizen](https://github.com/commitizen), though additional `devDependencies` and configuration files may be required, please review the tooling documentation for more information. 
+
+**Note on supporting Semantic Release versions**
+
+If the version of Semantic Release is pinned using [`SEMREL_VERSION`](#global-configuration) prior to v24, automated versioning via commit messaging may fail in unexpected ways. See [conventional-changelog-conventionalcommits v8.0.0 breaks semantic release](https://github.com/semantic-release/release-notes-generator/issues/633) or consider upgrading the pinned version to v24 or better to restore behaviors.
