Security is our number one priority. Chromebooks get automatic updates every four weeks that make your laptop more secure and help it last longer. And starting next year, we’re extending those automatic updates so your Chromebook gets enhanced security, stability and features for 10 years after the platform was released. A platform is a series of components that are designed to work together — something a manufacturer selects for any given Chromebook. To ensure compatibility with our updates, we work with all the component manufacturers within a platform (for things like the processor and Wi-Fi) to develop and test the software on every single Chromebook. Starting in 2024, if you have Chromebooks that were released from 2021 onwards, you’ll automatically get 10 years of updates. For Chromebooks released before 2021 and already in use, users and IT admins will have the option to extend automatic updates to 10 years from the platform’s release (after they receive their last automatic update). A good thing… Without any additional strings other than are already attached to a Chromebook? This can’t be. In all seriousness, ten years of updates for laptops that are often quite cheap and disposable is simply good news, and ensures that Chromebooks can be passed on for longer than they could before.

Wendy’s opens in Leeds. The American burger chain’s new spot at the corner of The Headrow and Briggate is part of its plans to have 45 restaurants in the UK by the end of the year and follows openings in Sheffield and Lincoln in recent months.

A frequent question in the open source CMS world is a variation of: “Which is better, Drupal or WordPress?” 
There’s not a simple answer to the WordPress vs Drupal question. Many have a strong bias towards one content management system or the other, but often, staunch opinions on the subject are based on a few cursory facts or outdated information.

Following last week’s beta, version 2.0.0 of re2 (Ruby bindings to Google’s RE2 “fast, safe, thread-friendly” regular expression library) is now available from RubyGems. Unlike version 1, it no longer requires the underlying RE2 library to be installed separately as it is now vendored with the gem and precompiled, native gems are available for Linux, Windows and macOS.

We are pleased to announce the release of Ruby 3.3.0-preview2. Ruby 3.3 adds a new pure-Ruby JIT compiler named RJIT, uses Lrama as a parser generator, and many performance improvements especially YJIT.

RJIT

• Introduced a pure-Ruby JIT compiler RJIT and replaced MJIT.
  • RJIT supports only x86_64 architecture on Unix platforms.
  • Unlike MJIT, it doesn’t require a C compiler at runtime.
• RJIT exists only for experimental purposes.
  • You should keep using YJIT in production.
• If you are interested in developing JIT for Ruby, please check out k0kubun’s presentation on Day 3 of RubyKaigi.

Use Lrama instead of Bison

• Replace Bison with Lrama LALR parser generator Feature #19637
  • If you have interest, please see The future vision of Ruby Parser

YJIT

• Major performance improvements over 3.2
  • Support for splat and rest arguments has been improved.
  • Registers are allocated for stack operations of the virtual machine.
  • More calls with optional arguments are compiled.
  • Exception handlers are also compiled.
  • Instance variables no longer exit to the interpreter
    with megamorphic Object Shapes.
  • Unsupported call types no longer exit to the interpreter.
  • Integer#!=, String#!=, Kernel#block_given?, Kernel#is_a?,
    Kernel#instance_of?, Module#=== are specially optimized.
  • Now more than 3x faster than the interpreter on optcarrot!
• Metadata for compiled code uses a lot less memory.
• Generate more compact code on ARM64
• Option to start YJIT in paused mode and then later enable it manually
  • --yjit-pause and RubyVM::YJIT.resume
  • This can be used to enable YJIT only once your application is done booting
• ratio_in_yjit stat produced by --yjit-stats is now avaiable in release builds,
  a special stats or dev build is no longer required.
• Exit tracing option now supports sampling
  • --trace-exits-sample-rate=N
• More thorough testing and multiple bug fixes

Other Notable New Features

Other notable changes since 3.2

IRB

IRB has received several enhancements, including but not limited to:

• Advanced irb:rdbg integration that provides an equivalent debugging experience to pry-byebug (doc).
• Pager support for commands like ls and show_cmds.
• More accurate and helpful information provided by the ls and show_source commands.

In addition, IRB has also undergone extensive refactoring and received dozens of bug fixes to facilitate easier future enhancements.

Compatibility issues

Note: Excluding feature bug fixes.

Removed constants

Stdlib compatibility issues

ext/readline is retired

• We have reline that is pure Ruby implementation compatible with ext/readline API. We rely on reline in the future. If you need to use ext/readline, you can install ext/readline via rubygems.org with gem install readline-ext.
• We no longer need to install libraries like libreadline or libedit.

What is Ruby

Ruby was first developed by Matz (Yukihiro Matsumoto) in 1993,
and is now developed as Open Source. It runs on multiple platforms
and is used all over the world especially for web development.
