[ANN] Magma release 41.2

I have just posted another minor maintenance release for Magma 41 called "41.2" to SqueakMap and the "Magma" project of squeaksource.com.

Release notes:

- Some low-level optimizations to maUint:at: resulting in better performance. - Now running MaTimers at userInterruptPriority-1 instead of userInterruptPriority+1. Afterall, they're only producing application data, so let's not supercede the real need for userInterruptPriority processes. - Improved support for subclasses of Dictionary and Set. - Fixed performance regression; don't #abort when server #refreshView; it is only necessary to #refresh, it will improve significantly server latency when a lot of commits are being performed.
