+**Changed in Veilid 0.4.4**
+
+veilid-core:
+- Improved termination conditions for DiscoveryContext, faster shutdown acknowledgment
+- Network class discovery from 25s to 5s in worst case
+- Moved some futures to the heap with Box::pin to reduce risk of stack overflows
+- Restore punishment for FailedToVerifySenderPeerInfo
+- Convert inbound relay loop notification from an error to a NetworkResult
+- Relays were being picked before we had good stats on their performance. Relays are now optimized to be within the top 25% of p90 latencies
+- LatencyStats now have median 80% average, p90, p75, and p50 latency numbers
+- RPC Answer stats now are split by 'ordered' and 'unordered' protocols
+- Unordered protocols are given a higher tolerance for lost answers before being marked 'unreliable'
+- Fix race condition in TTL code for udp hole punching
+- Correct use of IPV6_UNICAST_HOPS socket option instead of IP_TTL for ipv6 sockets
+- Move relaying to a relay worker pool
+- Connection table and RPC locking improvements
+- Remove TCP connection retries
+- Deadlock bugfix in relay code
+- 'Finding more nodes' tasks now use PreferOrdered sequencing
+- Fix deadlock in veilid_api duration testing
+- Correct offline_subkey_writes inflight reporting
+- Simplify upnp code, eliminate useless high-latency retry logic, and ensure it doesn't conflict with NAT detection
+
+veilid-python:
+- Fix async context implementation so it works correctly when re-entrant (nested `async with` blocks)
+- Validate types for API calls, will raise an assertion error if type is unexpected
+- Add more stress tests
+
+veilid-wasm:
+- fork tracing-wasm and add output filter for veilid log key
+
+general:
+- Added some pedantic clippy lints, moved lint config into workspace Cargo.toml
+- Fixed async-std support
+- Added windows and macos clippy lints to CI via earthfile
+- Upgrade all pinned crate dependencies
