This prerelease will be the key version for the v1.18.0 test plan.

It's a short-lived release hopefully and mostly just for testing.

Installation/Upgrade

See the installation instructions for details, but it's easy:

• Please stop all projects first, this does no harm: ddev poweroff
• macOS Linux, and WSL2 Homebrew (ddev-edge channel only): brew install drud/ddev-edge/ddev or just brew upgrade drud/ddev-edge/ddev ). (You may need a brew update for homebrew to find the new release.).
• Traditional Windows: Use choco upgrade -y --pre ddev to get this one, or download the ddev_windows_installer below.
• Linux and macOS with the install_ddev.sh script: Download the script, make it executable, and run it with the version: ./install_ddev.sh <version>
• And anywhere, you can just download the tarball or zipball, untar or unzip it, and place the executable in your path where it belongs.
• Consider ddev delete images after upgrading to free up disk space used by previous docker image versions. This does no harm.

Key changes in v1.18.0-rc4

• The headline remains experimental Mutagen support, offering vastly faster webserver performance. See the docs - it's really cool. Please make sure no competing mutagen instances are running (use killall mutagen) and thenddev config --mutagen-enabled && ddev start. See docs and article for performance details. This great feature was sponsored by Tag1 Consulting.
• Massive redesign of ddev describe and ddev list, with optional global table styles for each.
• PHP8.1beta3 is included
• These releases solve an obscure problem inside the web container that only happens on Mac M1 with some clients and some https servers that results in a Segmentation Error.
• xhprof integration now includes memory usage

Minor changes

• It is now possible to omit_containers[ddev-router] for situations where another reverse proxy is provided (like gitpod)
• ddev logs can now take a project-name argument
• Various bugfixes
• Improved interoperability with PhpStorm for running phpunit tests and composer integration.
• PHP_IDE_CONFIG is now set everywhere it needs to be, and not set in the context of php-fpm. Improves command-line and other interoperability.

Caveats

• docker-compose v1.25+ or docker-compose v2.0.0-rc2+ are now required
• .ddev/mutagen.yml has moved to .ddev/mutagen/mutagen.yml. And if you had edited it and taken over the file, please update based on the current .ddev/mutagen/mutagen.yml
• .ddev/xhprof/xhprof_prepend.php has been updated; if you took it over, please edit to base on current.
