# [RFC] Deprecations for PHP 8.6

**[externals.io](https://daily.dev/sources/externals)** · 95 min read · 0 upvotes · 0 comments

## Summary

The PHP internals mailing list thread covers the RFC for deprecations planned for PHP 8.6, compiled from proposals submitted over the past year. Each deprecation will be voted on individually, with a freeze deadline of July 13th. A notable debate emerges around whether proposals should include formal impact analyses. Juliette Reinders Folmer argues it is irresponsible to vote without impact data, while Tim Düsterhus counters that deprecations are not breaking changes and that impact analyses based on Packagist packages are inherently biased and incomplete. Rowan Tommins sides with Juliette, stating he will vote 'No' on any proposal lacking impact information. One concrete example shared is the 'return-in-finally' deprecation, where an analysis of ~5000 Composer packages found only 12 affected sites across 9 packages (0.18%), with 3 being actual latent bugs.
