With the release today of Frameworks 5.66.0, the usual full monthly update of all of KDE has moved to all users, this include bug fix releases of plasma 5.17 and KDE Apps 1912.1. No major changes or issues were announced.
Bigger chance you will notice in this update though is the move from tar.xz to tar.zst for the package compression. ZSTD brings a significant improvement of decompression speed over XZ, while bringing only a marginal larger package size. For you as a user, this is fully automated (unless you are trying to run a complete unsupported system that has not been updated in a year, you will need libarchive build with zstd support, added to the repo early 2019) , so you will slowly see all your packages being replaced with tar.zst.
