+## `bytemuck_derive` changelog
+
+## 1.5.0
+
+* The `Zeroable` derive now allows custom bounds. See the rustdoc for an explanation.
+
+## 1.4.1
+
+* Move the `syn` dependency to use version 2.
+  This should not affect the public API in any way.
+
+## 1.4.0
+
+* `ByteEq` and `ByteHash` derives will make `Eq` and `Hash` impls that treat the
+  value as a `&[u8]` during equality checks and hashing. This provides a large
+  codegen improvement for some types.
+* Derives of `repr(int)` enums should now accept byte literal values as the
+  discriminant.
+
+## 1.3.0
+
+* Allow `repr(transparent)` to be used generically in `derive(Pod)`.
+
+## 1.2.1
+
+* Fixed a regression of the `align(N)` attribute that occurred during otherwise
+  routine cleanup.
+
+## 1.2.0
+
+* Apparently our minimum required version of `syn` went up without anyone
+  noticing for a while. Because of a bump in our `syn` requirements, we're also
+  issuing this minor version bump in the `bytemuck_derive` crate. Because it's
+  possible to *reduce* the minimum required version of a dep in only a patch
+  release, I'm going to ratchet the required version of `syn` all the way up to
+  "current" (1.0.99). If absolutely necessary we could probably reduce the
+  minimum `syn` version again in a patch release for 1.2, but I don't want to
+  play this dance too much so I'd rather make each jump as big as can possibly
+  be. [Issue 122](https://github.com/Lokathor/bytemuck/issues/122). **Note:**
+  While the core `bytemuck` crate continues to keep building on rustc-1.34.0,
+  the `bytemuck_derive` crate is considered an opt-in bonus feature (which
+  doesn't do anything you couldn't trivially do yourself) and so it does not
+  support a specific MSRV.
+
+## 1.1.1
+
+* Adjusted the license files to use full files rather than symlinks.
+  [PR](https://github.com/Lokathor/bytemuck/pull/118)
+  The license is unchanged, just no more symlinks.
+
+## 1.1.0
+
+* Updated to work with `bytemuck-1.9.0`
+
+## 1.0.1
+
+* [yanchith](https://github.com/yanchith) fixed the derive checks code to make clippy more happy.
+[PR 45](https://github.com/Lokathor/bytemuck/pull/45)
+
+## 1.0.0
+
+* Initial stable release.
