## What's New ## What's New
Here's whats new in 2.29.1:
* Debloats clap by deduplicating logic and refactors for a ~57% decrease in code size! This is with zero functinoality lost, and a slight perf increase!
* Change the bash completion script code generation to support hyphens.
* Fix completion of long option values in ZSH completions
* Fixes broken links in docs
* Updates contributors list
* Fixes the ripgrep benchmark by adding a value to a flag that expects it
Here's whats new in 2.29.0: Here's whats new in 2.29.0:
* **Arg:** adds Arg::hide_env_values(bool) which allows one to hide any current env values and display only the key in help messages * **Arg:** adds Arg::hide_env_values(bool) which allows one to hide any current env values and display only the key in help messages
