@ -12,6 +12,7 @@ This section is for changes merged to the `major` branch that are not also merge
- For loop control variables are no longer local to the for block (#1935).
- A literal `{}` now expands to itself, rather than nothing. This makes working with `find -exec` easier. (#1109, #4632)
- Successive commas in brace expansions are handled in less surprising manner (`{,,,}` expands to four empty strings rather than an empty string, a comma and an empty string again). (#3002, #4632).
- `%` is no longer used for process and job expansion. `$pid` and `$last_pid` have taken the place of `%self` and `%last` respectively. (#4230, #1202)
## Notable fixes and improvements
- `wait` builtin is added for waiting on processes (#4498).
