v1.5.15

⚠️ Reminder: a new release of symfony1 does not mean you might use it for new projects. You MUST use Symfony 6 instead.

Most of changes for that release are for PHP 7.4, 8.0, 8.1 and 8.2 compatibility.

What's Changed

• php 8.2 support by @thirsch in #274

• Fixed a few more php 8 issues by @thirsch in #272
• Prepared release 1.5.15 by @thirsch in #275
