  • Hooks arrived and the class component did not have to go

    Deep dive15 min read

    16.8 shipped on 6 February and the migration pressure was immediate and mostly self-inflicted. What they actually solve, and what the dependency array means.

  • PHPUnit 8 and the deprecations with a deadline

    Deep dive8 min read

    void return types on setUp, and a fatal error rather than a warning. The mechanical pass, the one it cannot do, and the assertion split that is not…

  • assertRegExp became assertMatchesRegularExpression

    Note2 min read

    8.x deprecates a set of assertions with names that were shortened years ago, and 9 removes them — so the warnings are a deadline rather than noise. The…

  • set -euo pipefail at the top of every script

    Note2 min read

    A deploy script without it continues after a failed command, so a failed composer install is followed by a successful symlink swap and a broken site reported as…
