🌲 Timber

v5.0 - 12 Aug 2026

Added

• Log lines are mirrored into [Leaf Crash](https://leafphp.dev/docs/routing/error-handling) as breadcrumbs, so error reports show what your app logged on the way to a crash
• Added a full test suite covering levels, writers and formatting, run through Alchemy (logger's first)

Fixed

• Setting an invalid log level warns and keeps the previous level instead of misbehaving quietly
• LogWriter throws a RuntimeException when the log file is missing and createFile is false, replacing the fatal error (and keeping logger clean on PHP 8.4)
• Log writes append using the file pointer instead of rewriting the whole file, so production logs stay fast at any size. The old newest-first layout is available with log.mode: 'prepend' (thanks @ghosthi) for the report and design)

Changed

• Logger now requires PHP 8.2+
