Have updated changelog in alpha/beta versions

Currently, the changelog doesn't show you changes for the last stable version if you're on alpha/beta ver.

For example, if you're on 2.21 alpha/beta and you switch to 2.22 alpha beta, you don't get the changelog for 2.21 stable versions.

Is there any chance this can change? I like the overview of changes (the writing is fire btw) and it's useful if there's a good change I've missed somewhere.
