   `ipnetwork` is part of the public API.
 * Upgrade crate to Rust 2021 edition.
 * MSRV bumped to 1.69 due to use of `CStr::from_bytes_until_nul`.
-* Replace `error-chain` generated errors with manually implemented error types.
-* Remove `build_internal` methods on `FilterRuleBuilder` and `RedirectRuleBuilder`.

+* Replace `error-chain` generated errors with manually implemented error types. This changes
+  the public API of the error related types quite significantly. Also the chain of errors
+  will be different. But it should be as easy to destructure and handle errors as before,
+  and error messages should be at least as informative.
 
 ### Removed
 * Remove `PoolAddrList::to_palist` from the public API. It should never have been exposed.
+* Remove `build_internal` methods on `FilterRuleBuilder` and `RedirectRuleBuilder`.
