Currently the process of release is as following

There is a github action that triggers on push to master and will build the code and create a draft release of current version on master, every commit to master will override that release until the version is bumped.

Wait for any builds

Wait for all builds on master that we want to be included in the current release to finish (best practice is wait for all builds on master to finish)

Bump version

Bump version in this file
https://github.com/block-core/blockcore/blob/1.0.23/src/Directory.Build.props#L3

Run changelog update.

In the project root run the command
npm run changelog
This will modify the fle
https://github.com/block-core/blockcore/blob/1.0.23/CHANGELOG.md

Release

On the release tab there will be a release draft created for the previous version (before the bump, bumping the version will create a new release draft)
Optional - update the change log in the release as well
Click "Release" on the release

Reminder we need to move this to the main repo (and potentially to documentation repo)
