 ## 0.17 - Unreleased
 
-* Change integers to newtypes in various public APIs
+Major changes:
+* Change many integer-based public API parameters to strongly-typed newtypes and bitflags. 
+  This breaking changes affects many of the methods on `Filesystem`
+* Change `Filesystem` trait methods to use `&self`, and require mounted filesystems to be `Send + Sync + 'static`
+* Improve typed error handling across request/reply APIs
+* Replace `Vec<MountOption>` mount APIs with a structured `Config` API, including ACL option handling
+* Feature flags `abi-7-xx` are now ignored and will be removed in 0.18, with compatibility checks moved to runtime behavior
+* Remove the old ABI-specific feature-flag surface (`abi-7-9` through `abi-7-19`, plus tooling/docs/examples references)
+* Add support for multiple event loops per session, which can be enabled via `Config::n_threads`
+* Add experimental async API (`AsyncFilesystem`)
+
+Minor changes:
+* Rename `BackgroundSession::join` to `umount_and_join`, returning `io::Result<()>` instead of panicking
+* Add `FUSE_DEV_IOC_CLONE` support and improve passthrough descriptor handling (`ReplyCreate`, `ReplyOpen`, `BackingId`)
+* Improve passthrough descriptor handling (`ReplyCreate`, `ReplyOpen`, `BackingId`)
 * Add `FileType` conversion from std `FileType`
-* Rename `BackgroundSession::join` to `umount_and_join`
-  and change it to return `io::Result<()>` instead of panicking
+* Add option to explicitly choose `libfuse2` or `libfuse3`, prefer `libfuse3` by default
+* Support building without libfuse on BSD
+* Remove remaining `osxfuse` support and improve `macfuse` compatibility
 * The path to the `fusermount` binary can be specified with the `FUSERMOUNT_PATH` environment variable
-* `allow_root` or `allow_other` must be specified when using `auto_unmount`
-* feature flags `abi-7-xx` are ignored and will be removed in 0.18.
+* `allow_root` or `allow_other` must be enabled when using `auto_unmount`
+* Update and expand documentation
+
+Internal changes:
+* Improve Linux/BSD/macOS test coverage by migrating mount tests to `fuser-tests` and expanding CI
+* Rework session lifecycle internals (handshake/session startup, destroy ordering, and unmount error propagation)
