Nice, do you have a timeframe in mind for the release, or this will be "when it's ready"? Also, a suggestion: do not create a `Pharo12` branch yet but use a master/main one (and make it the default branch). It helps newcomers to understand more easily the structure of the project. -J ________________________________________ De : Esteban Lorenzano <estebanlm(a)netc.eu> EnvoyÃ© : 10 mars 2023 05:03 Ã : Pharo Development List Objet : [Pharo-dev] [ANN] preparing for release, freezing enhancements :) Hello, We are slowly preparing to release Pharo 11.

While I'm not able to commit time to help due to personal commitments taking all my spare time at the moment - it does make me smile reading the list of improvements and the fact the people care about this stuff.

Re: Pharo VM Release - v10.0.0

by Gabriel Cotelli

Congratulations on the new VM release! Are there some reasons to skip this version as the default for Pharo 10 images? Or is it just not worth the effort, given the close release date of Pharo 11? I need to update our Pharo docker images and I want to understand if it's better to wait for the Pharo 11 release.

Re: Pharo VM Release - v10.0.0

by Norbert Hartl

This is yet again an impressive list of good things. Always appreciated are "Remov*" features :) I'm especially interested in ephemerons and how it improves the weak structures in the image. Hope the image support that makes use of the vm features follows soon. A wish would be to know a bit more about the permanent space news. Great work as always. Thanks!

Pharo VM Release - v10.0.0

by tesonep＠gmail.com

Hello, we have released a new version of the Pharo VM for Pharo 11. This VM is accessible right now from Zero-Conf, updating it in the Pharo Launcher or using the usual downloads (as described in pharo.org/download) OBS packages are still in work and will come later. This is the new VM that will be stable for Pharo 11 release, it is also compatible with Pharo 10 images but it is not the default for Pharo 10. It has a lot of changes and improvements, as it is the result of more than a year and a half of improvements, clean-ups, and bug fixes. Changelog v10.0.0 - Slang (Smalltalk to C Translator) - Introducing a C AST to ease the generation of C Code - Having a Pretty Printer for C AST - Translation Tests - Fixing Translation Issues - Clear separation between Slang and VM code - Improving Cast generation - Clean Up: - Remove Old Bytecode Set - Remove Old Block Implementation - Simplification of the Primitives - Removing Unused / Old Code / Dead Code - Cleanup / Removal of Old Unused primitives - Removing Old FFI Implementation - Removing MT Experiment from the code base (Kept in own branch) - Fixing Compilation Warnings - Improving Type annotations to fix bugs in the translation / compilation - Removing Conditional Code on Old Configurations / Features - Renaming Concepts to be inline with Common terminology - Remove Newspeak, Multiple Bytecode and Old Memory Managers - Removing Unused Plugins - Tests - GNUification Tests - Tests for Math primitives including overflow and conversion testing. - Tests for comparison primitives (Equals / Not Equals / Less than / Less or Equals / Greater Than / Greater or Equals) - Testing Primitives for objects Pinned in Memory - Testing Math Primitives for Immediate Classes (SmallFloats / SmallIntegers) - Improving Simulation Infrastructure - Using Sista Bytecode in all Tests - Updating Unicorn version - Improving Machine Code emulation - Testing Image Read / Image Write - Using the same memory map in Tests and Execution - Testing Ephemerons - Become Primitives - Ephemeron - Fix for large ammounts - Make it available - Testing Signal Finalizations - Fixing Become Errors. - Fixing XRay Primitive - Single-Instruction Multiple-Data (SIMD) initial Support: - Initialization of new objects using SIMD (ARM64) - Adding Bytecode Extensions to support SIMD instructions - Adding Vector Registers - Vector Register bytecodes - Auto Localization of Interpreter loop variables and edge detection simplifying development and minimizing code - ImageReader / ImageWriter reification needed for Permanent Space. - Improving the Memory Map of the VM (Using constant positions) - Dependencies Improvements Thanks a lot, and any doubt please let us know.
