This week, Symfony 2.7.42, 2.8.35, 3.4.5 and 4.0.5 maintenance versions were published. In addition, Symfony improved the accessibility of the Bootstrap 4 form theme to comply with the WCAG standard: it fixed some HTML issues, added new attributes and improved how form errors are displayed. Finally, it was proposed a way to simplify the User and UserChecker.
This week, development activity was focused on finishing some of the new features for the upcoming Symfony 4.1 version: added support for 307 and 308 HTTP redirections, allowed writing prepared console commands, added support for configuring Argon2i encryption and deprecated the bundle notation.
This week, the upcoming Symfony 4.1 version added support for immutable dates in forms, added new output formats for the workflow:dump command and added support for hasser methods in PropertyInfo. In addition, work continued to make Symfony builds reproducible and to improve the Routing performance.
This week Symfony released 2.7.41, 2.8.34, 3.3.16, 3.4.4 and 4.0.4 maintenance versions. The 3.3.16 release will be the last one of the 3.3 branch, which ended its support for bug fixes this week.
