## Things To Know About This Crate

- It will never reach v1.0.
- Minimum Supported Rust Version (MSRV) is latest stable at the time of each release.
- Breaking changes will likely happen on most 0.x version bumps.
- Documentation might be limited for some items.
- Items that graduate to Actix Web crate will be marked deprecated here for a reasonable amount of time so you can migrate.
- Migrating will often be as easy as dropping the `_lab` suffix from imports when migrating.
