@JuliaRegistrator register

Registration pull request created: JuliaRegistries/General/139154

Recommendation: add release notes

Release notes help your users know what has changed in the new version. For breaking releases in particular, it's recommended to document what breaking changes were made (or point to where changes can be found, such as a changelog).

To add release notes, just add markdown formatted text underneath the comment after the text "Release notes:" and it will be added to the registry PR, and if TagBot is installed it will also be added to the release that TagBot creates. i.e.

@JuliaRegistrator register

Release notes:

## Breaking changes

- blah

To add release notes to this registration, just re-invoke JuliaRegistrator and the PR will be updated.

Tagging

After the above pull request is merged, it is recommended that a tag is created on this repository for the registered package version.

This will be done automatically if the Julia TagBot GitHub Action is installed, or can be done manually through the github interface, or via:

git tag -a v1.1.3 -m "<description of version>" 5a735b95bf9e4e3149403b138d7d2512d116a94e
git push origin v1.1.3
