@ -4,6 +4,15 @@ CHANGELOG
0.53.1
------
- Bug fixes and minor improvements
- Better cache management and improved rendering for `--tail`
- Fixed crash when using `--tiebreak=end` with very long items
- Fixed mouse support on Windows
- zsh 5.0 compatibility (thanks to @LangLangBart)
- Fixed `--walker-skip` to also skip symlinks to directories
- GET endpoint is now available from `execute` and `transform` actions (it used to timeout due to lock conflict)
```sh
fzf --listen --bind 'focus:transform-header:curl -s localhost:$FZF_PORT?limit=0 | jq .'
