 ## `bytemuck_derive` changelog
 
+## 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
+  "curret" (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)

 ## 1.1.1
 
 * Adjusted the license files to use full files rather than symlinks.
