Drush 10 removes many deprecated APIs and functions. It's lean and clean. Drush 10 works great with improvements in the upcoming Drupal 8.8, like the new Config Transform and Exclude APIs.

Commandfiles written for Drush 9 are often already compatible with Drush 10. All you should do is expand the constraint in your module's composer.json (see extra/drush section). See this patch from Devel module. Commandfiles that aren't part of modules don't need any composer.json changes.

Drush 10 should work fine when making remote calls into a Drush 9.6+ environment. This helps during the brief period when you upgrade to Drush 10 locally but still need to make calls into a Prod instance that is still on Drush 9.

This release features significant new features and a major refactor of our site alias remote communication. If Drush had a marketing department, they would have insisted on the number 10.0. We don't, so 9.6 it is. We did our very best to preserve existing APIs - please report any breakage.

Highlights

• Deprecate drush_invoke_process(), backend.inc and context.inc. These are no longer used by Drush core and commandfiles are encouraged to use their replacements like Drush::drush(). These APIs will be removed in Drush 10. This is a HUGE win for the maintainability of Drush. #3758
• Site aliases may now point into a Docker container #3835
• Now 100% ✅ on Windows. All PRs tested for regressions (via Appveyor).
• Now 100% ✅ for sqlite and postgres databases. Mysql has always been ✅. Our test bots run these tests every night.
• Add --filter to many commands (#3718). You may now filter output from any tabular commands. An example: drush pm:list --filter=ctools. See docs for details and general info about output formats.
• Unish, our test framework, can now run integration tests without a heavy setUp(). Tests are being ported over.
• Use Drupal DB during bootstrap instead of CLI (#3800). This enables you to run all but the sql:* commands without the mysql client. Useful for minimalist Docker environments.

Other Noteable Changes

• Fix significant bug where pm:security misses required security updates. (#3766)
• Allow Symfony Console commands to be used in php:cli. (#3770). Did you know that Drush can discover and run standard Symfony Console commands?
• Document how to deal with dynamic usernames in a site.yml file. 9fb7658
• Obsolete the unused and unmaintained core:execute command. Use site:ssh instead. (#3803)
• Add ssh.pipefail config and use it in sql:dump --gzip (#3818)
• PGPASSFILE passed via Process not on commandline (#3833)
• Use --uri from commandline over uri in an alias (#3966)

This release fixes a few minor bugs from the previous release.
