Installation/Upgrade

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

macOS Homebrew and Linux Linuxbrew: brew upgrade ddev
Linux or macOS via script:
curl https://raw.githubusercontent.com/drud/ddev/master/install_ddev.sh | bash
Windows: Download the ddev_windows_installer.v1.5.2.exe above.
And anywhere, you can just download the tarball or zipball, untar or unzip it, and place the executable in your path where it belongs.

Key changes in v1.5.2:

Linuxbrew is our preferred install/upgrade technique on all Linux distributions.
PHP 7.3 now has php-memcached in web container
ghostscript added to web container
php-apcu added to web container, significant performance boost. For Drupal 8 $settings['class_loader_auto_detect'] = FALSE; is added to the settings.ddev.php and it increases performance quite a lot with php-apcu. Thanks to @mglaman for the suggestion in Stack Overflow
mariadb in db container upgraded from 10.2.15 to 10.2.19-r1
ddev import-db and ddev pull now sport a nice progress bar letting you know how much time you have for coffee. Thanks to @longwave for that!
