Hi all!

We just released the next version of the OpenSmalltalk VM.

Please find the binaries here:

(see VMMaker.oscog-mt.3184 and update.oscog-mt.6.mcm)

That version will be used in the upcoming Squeak 6.0 and also updated

bundles for Squeak 5.3. And probably in upcoming Cuis releases. :-)

Here is an attempt of a change log (since 2020):

- Adds ARMv8/Aarch64/ARM64 JIT incl. support for Apple M1

- Adds "fast C primitives" via #FastCPrimitiveFlag

- Adds support for catching exceptions in FFI callouts

- Adds #primitiveScreenScaleFactor (for DPI-aware images)

- Adds primitives 568 and 578 complementing 88 (primitiveSuspend)

- Adds #primitiveMultipleBytecodeSetsActive to update image format for SistaV1

- Adds VectorEnginePlugin

- Fixes regressions in ARMv6 support

- Fixes performance regressions of -metal and -opengl backends on macOS

- Fixes -core-graphics backend on macOS

- Fixes Retina scaling on macOS, i.e., support "backing scale factor"

- Fixes primitive 126 to fail on graphics backends w/o composition buffer

- Fixes regressions in vm-display-fbdev on Linux

- Fixes time sync (e.g., for DST) on Windows

- Fixes UDP binding on Windows

I am sure that I forgot something especially in plugin code. Please expand on this.

BIG THANKS to everybody who has worked on this release! Personally, I would like

to thank Eliot, who is a great software architect who keeps on making the OSVM

faster with every commit. Thank you!

Best,

Marcel (on behalf of the OSVM core dev team)
