@ -167,6 +167,8 @@ Subtle changes (i.e. compiler won't catch):
- `ArgMatches::is_present` no longer checks subcommand names
- Some env variable values are now considered false for flags, not just "not-present" ([clap-rs/clap#2539](https://github.com/clap-rs/clap/issues/2539))
- Changed `...`s meaning in usage parser. Before, it always meant `multiple` which is still true for `--option [val]...`. Now `[name]... --option [val]` results in `ArgSettings::MultipleOccurrences`.
- Usage exit code changed from `1` to `2` ([clap-rs/clap#1327](https://github.com/clap-rs/clap/issues/1327))
- Reject `--foo=bar` when `takes_value(false)` ([clap-rs/clap#1543](https://github.com/clap-rs/clap/issues/1543))
Easier to catch changes:
- When using `no-default-features`, you now have to specify the `std` feature (reserved for future work)
