 # CHANGELOG for crate `multiboot2-header`
 
-## Unreleased
+## 0.3.0 (xxxx-xx-xx)
 - MSRV is 1.68.0
 - renamed the `std` feature to `alloc`
 - added the optional `unstable` feature (requires nightly)
   - implement `core::error::Error` for `LoadError`
+- depends on `multiboot2@v0.16.0`
 
-## v0.2.0 (2022-05-03)
+## 0.2.0 (2022-05-03)
 - **BREAKING** renamed `EntryHeaderTag` to `EntryAddressHeaderTag`
 - **BREAKING** some paths changed from `multiboot2_header::header` to `multiboot2_header::builder`
    -> thus, import paths are much more logically now
 - internal code improvements
 
-## v0.1.1 (2022-05-02)
+## 0.1.1 (2022-05-02)
 - fixed a bug that prevented the usage of the crate in `no_std` environments
 - added a new default `builder`-feature to Cargo which requires the `alloc`-crate
   (this feature can be disabled which will also remove the dependency to the `alloc` crate)
 
-## v0.1.0 (2021-10-08)
+## 0.1.0 (2021-10-08)
 - initial release
