+# engineioxide 0.17.4
+* MSRV: rust-version is now 1.94
+* fix: issue [#731](https://github.com/Totodore/socketioxide/issues/731). Memory leak with unclaimed engine.io sessions whose WebSocket upgrade is started but never completed.
+* fix: missing packet separator when polling a parked v4 encoder.
+* fix: incorrectly merged binary/string packets when polling a parked v3 encoder.
+* fix: v3 encoded payload size is never re-computed for max payload size threshold.
+* fix: v3 decoder infinite loop with malformed packet
+* fix: base64 binary packet protocol mismatch with payload starting with `4`.
+* fix: fix potential panic in debug with malicious v3 packets.
+* fix: expect b64 query param to be equal to 1 or true to enable b64 encoding.

 # engineioxide 0.17.3
 * fix: issue [#719](https://github.com/Totodore/socketioxide/issues/719). Because of an unpinned dependency on `tokio-util`
 building engineioxide would fail with `tokio-util < 0.7.14`.
