In case you missed the news - #Ruby 3.5 is going to become Ruby 4.0 to celebrate the 30th Ruby anniversary github.com/ruby/ruby/co...
It's a bit odd to make such a decision only a month and half before the release (Christmas day), but it is how it is.

New incredible detail here: ICE says a match in its facial recognition app Mobile Fortify is a "definitive" determination of a person's status, and that this overrides birth certificates. This is an app ICE is using in the field to scan people

There’s actually a concept in information theory that formalizes this, called “data processing inequality”—which is “post-processing cannot increase information”.
This is rather obviously true but if you’re interested there’s also mathematical proof:

Now’s a good time to add CHECKSUMS to your Gemfile.lock. For an existing project:
bundle lock --add-checksums
This will add a new CHECKSUMS section to the lockfile that Bundler will keep up to date.
Now, configure Bundler to always include checksums:
bundle config lockfile_checksums true
bundle lock --add-checksums
This will add a new CHECKSUMS section to the lockfile that Bundler will keep up to date.
Now, configure Bundler to always include checksums:
bundle config lockfile_checksums true
