 ## [0.5.0] - 2021-07-20
 ### Changed
 - [PR#38](https://github.com/EmbarkStudios/spdx/pull/38) fixed various clippy lints which also bumps the MSRV to [1.53.0](https://blog.rust-lang.org/2021/06/17/Rust-1.53.0.html). Previously, PR#37 had bumped the MSRV to 1.52 so now this crate will check the MSRV so changes are intentional.
