# Changelog
This is a log of features and fixes to the source code.
Documentation files are ignored, as are refactoring changes.
For the interested, the commit history is readable too (I know the art of rebasing).
## 4.1.1
* Allow "$*" (no need to rewrite it to "$@" as long as the quotes are on).
* Recognise premature esac to avoid parse error (seen on rustup.sh).
* Write this changelog.
* Cargo Clippy compliant.
* Unittests! Currently focused on corner cases that are hard to moduletest,
namely lookahead.
* Corner cases in the keyword detection inside the `case` statement were fixed.
This would manifest as false positive and false negative detection of the `in`
and `esac` keywords, followed by a likely parse error.
This stems from version 4.0 and was not seen in the wild AFAIK.
The most glaring bug was false positive detection when prefixed.
Less so were the false negatives around asking for more lookahead.
Less so were the false negatives related to lookahead.
* The special variables $$, $! and $- are now recognized.
