A very large update just moved to the build repo, for python3, this is a first full python rebuild since python3 became the default python version, so a lot of new packages had to be added to the rebuild list.
For the core and main repo, all planned rebuilds are completed, apps are still ongoing, should be finished in a few hours.
If you find some issues with your applications, especially python (boost & icu were a fairly standard update/rebuild list), please note here.
