# Changelog Update
|
|
|
|
If you want to help with updating the [changelog][changelog], you're in the right place.
|
|
|
|
## When to update
|
|
|
|
Typos and other small fixes/additions are _always_ welcome.
|
|
|
|
Special care needs to be taken when it comes to updating the changelog for a new
|
|
Rust release. For that purpose, the changelog is ideally updated during the week
|
|
before an upcoming stable release. You can find the release dates on the [Rust
|
|
Forge][forge].
|
|
|
|
Most of the time we only need to update the changelog for minor Rust releases. It's
|
|
been very rare that Clippy changes were included in a patch release.
|
|
|
|
## How to update
|
|
|
|
### 1. Finding the relevant Clippy commits
|
|
|
|
Each Rust release ships with its own version of Clippy. The Clippy submodule can
|
|
be found in the [tools][tools] directory of the Rust repository.
|
|
|
|
To find the Clippy commit hash for a specific Rust release you select the Rust
|
|
release tag from the dropdown and then check the commit of the Clippy directory:
|
|
|
|
|
|
|
|
When writing the release notes for the upcoming stable release you want to check
|
|
out the commit of the current Rust `beta` tag.
|
|
|
|
### 2. Fetching the PRs between those commits
|
|
|
|
You'll want to run `util/fetch_prs_between.sh commit1 commit2 > changes.txt`
|
|
and open that file in your editor of choice.
|
|
|
|
* `commit1` is the Clippy commit hash of the previous stable release
|
|
* `commit2` is the Clippy commit hash of the release you want to write the changelog for.
|
|
|
|
When updating the changelog it's also a good idea to make sure that `commit1` is
|
|
already correct in the current changelog.
|
|
|
|
### 3. Authoring the final changelog
|
|
|
|
The above script should have dumped all the relevant PRs to the file you
|
|
specified. It should have filtered out most of the irrelevant PRs
|
|
already, but it's a good idea to do a manual cleanup pass where you look for
|
|
more irrelevant PRs. If you're not sure about some PRs, just leave them in for
|
|
the review and ask for feedback.
|
|
|
|
With the PRs filtered, you can start to take each PR and move the
|
|
`changelog: ` content to `CHANGELOG.md`. Adapt the wording as you see fit but
|
|
try to keep it somewhat coherent.
|
|
|
|
The order should roughly be:
|
|
|
|
1. New lints
|
|
2. Changes that expand what code existing lints cover
|
|
3. ICE fixes
|
|
4. False positive fixes
|
|
5. Suggestion fixes/improvements
|
|
|
|
Please also be sure to update the Beta/Unreleased sections at the top with the
|
|
relevant commit ranges.
