For customers who prefer to operate on stable branches, we have released an “R2”, or second release of the Io, 5.2 release. It includes multiple small stability improvements, crash fixes, update fixes for Linux ARM builds, and fixes to WARP, DWARF, and Ghidra Import.

As always, customers with active support on the development branch have access to these changes and more.
