+## [2.55.0] - 2024-12-30
+### Added
+- Support boost 1.87
+- "i2p.streaming.maxConcurrentStreams" tunnel's param to limit number of simultaneous streams
+- Separate thread for tunnel build requests
+- Show next peer and connectivity on "Transit tunnels" page
+- Tunnel name for local destination thread
+- Throttle incoming ECIESx25519 sessions
+- Send tunnel data to transport session directly if possible
+- Publish 'R' cap for yggdrasil-only routers, and 'U' cap for routers through proxy
+- Random tunnel rejection when medium congestion
+- Save unreachable router's endpoint to use it next time without introducers
+- Recognize symmetric NAT from peer test message 7
+- Resend HolePunch and RelayResponse messages
+### Changed
+- Removed own implementation of AESNI and always use one from openssl
+- Renamed main thread to i2pd-daemon
+- Set i2p.streaming.profile=2 for shared local destination
+- Reduced LeaseSet and RouterInfo lookup timeouts
+- Cleanup ECIES sessions and tags more often
+- Check LeaseSet expiration time
+- Handle NTCP2 session handshakes in separate thread
+- Limit last decline time by 1.5 hours in router's profile
+- Don't handle RelayRequest and RelayIntro with same nonce twice
+- Increased hole punch expiration interval
+- Send peer test message 6 with delay if message 4 was received before message 5
+- Pre-calculate more x25519 keys for transports in runtime
+- Don't request LeaseSet for incoming stream
+- Terminate incoming stream right away if no remote LeaseSet
+- Handle choked, new RTO and window size calculation and resetting algorithm for streams
+### Fixed
+- Empty string in addressbook subscriptions
+- ECIESx25519 sessions without destination
+- Missing RouterInfo buffer in NetDb
+- Invalid I2PControl certificate
+- Routers disappear from NetDb when offline
+- Peer test message 6 sent to unknown endpoint
+- Race condition with LeaseSet update
+- Excessive CPU usage by streams
+- Crash on shutdown
