Pharo - [VM] New VM Release

[VM] New VM Release

Hi all,<br>We wanted to share a new VM release, aimed at Pharo 14 images.<br>https://github.com/pharo-project/pharo-vm/releases/tag/v12.0.2-beta<br>Besides many cleanups and small improvements, this enables a soon-to-come stack overflow support.<br>For those interested in more details, I allowed myself to generate a digested changes log with some AI.<br>Those using zeroconf will see this change effective immediately.<br>Launcher users, do not forget to update your VMs.<br>Please consider this is a beta release.<br>Do not hesitate to communicate any issues you may find.<br>Cheers,<br>Guille Polito<br>Highlights<br>This is a major release featuring:<br>Frame unification and stack management improvements, delivering substantial interpreter and execution engine cleanups.<br>RISC-V JIT support, expanding platform coverage and future-proofing VM development.<br>New memory management capabilities, including direct old-space allocation and numerous GC and allocation improvements.<br>Extensive compiler and Slang/C translation work, with many correctness fixes, new tests, and improved inspection tools.<br>Platform and build modernization, including SDL updates, improved CI, cross-build support, and updated third-party dependencies.<br>Large-scale cleanup and refactoring efforts across the VM, interpreter, Cogit, PICs, and infrastructure.<br>VM Runtime,
