Changelog - DDMAL/CantusDB GitHub Wiki

Since early 2022, we've been keeping a log of changes to the code running on our production server within pull requests where we merge changes into our Production branch. Here is a list of links to these pull requests, including the date on which the PR was merged and the approximate time the changes went live on the Production server.

For each PR, a non-exhaustive list of significant changes (affecting the structure of the codebase, having implications for the data in the database, updates to version numbers for dependencies, etc.) is included as a sublist.
