In Symfony 4.4, routing config can exclude patterns, checking HTML contents is easier in tests, expressions support scientific numeric format, isGranted() deprecated checking multiple permissions and Twig linter included new options.

Symfony 4.4 adds many useful improvements, such as better PropertyAccess error messages, support for more only-of-type CSS selectors, a more flexible Range constraint, the option to sort extracted translation messages, an option to consider empty strings invalid and gitattributes files to exclude tests.

This week, the upcoming Symfony 5.1 version added MongoDB support for the Lock component, exception pages enabled the "dark theme" and the MicroKernelTrait was improved to make it easier to use and configure.

In addition to working on big new features, Symfony maintainers spend a lot of time working on invisible features that developers take for granted. This article shed light on some of these recent features.

In Symfony 4.4, we've improved the Profiler to display the details of the Mailer and HttpClient components, we've improved the Ajax requests panel and we've decreased the disk space needed to store each profile.
