 ## History
 
+- 1.5.5 (2019-02-20): `$_ZL_FZF_FLAG` can be used to override fzf flags, default to "+s -e".
 - 1.5.4 (2019-02-19): fixed: file/path existence detection fails on read-only fs (closed [#49](https://github.com/skywind3000/z.lua/issues/49) by [@contrun](https://github.com/contrun)).
 - 1.5.3 (2019-02-17): new `$_ZL_FZF_FLAG` for passing additional flags to fzf, add `-e` argument to fzf.
 - 1.5.2 (2019-02-16): be aware of all arguments in fzf completion.
