GUI Improved: Added advanced setting options: bittorrent.transfer_thread_pool, using worker threads for BT transmission encryption and decryption operations, disabled by default
GUI Improved: Added advanced setting options: bittorrent. advertising. external. utp-port, which notifies the external uTP port through PEX in NAT1 environment, defaults to true
GUI Improved: Added advanced setting options: dht.outbound_pps_imit, dht.outbound_pending_request_limit, dht.passive_reply_pps_limit, dht.passive_reply_pending_limit
GUI Improved: Remove advanced setting option: dht.udc_send_queue_threshold
GUI Improved: Added advanced settings option: network.udp_stocket_buffer_size_mb, default to 8MB
GUI Improved: The default value of advanced settings option network.max_connecting_connections_per_tracker changed to 0 (automatic)
GUI Improved: Added categories of "BT transmission thread", "DHT thread", and "uTP thread" to the CPU usage statistics in the traffic graph
GUI Improved: Add uTP Port column to the peer list of BT task, hidden by default
GUI Improved: The Add Peer dialog box in peer list of BT Task supports # and // inline comments
GUI Improved: Improve the window dark mode switching mechanism
GUI Improved: Added options in Remote Access Page: Local client bypass authentication, IP whitelist clients bypass authentication
GUI Improved: Added command-line parameter --profile, which can specify the program configuration file directory for independent testing
GUI Improved: The number of HTTP Tracker connections in the statistics page is divided into two categories: pending and half open
GUI Improved: Add DHT packet status information to the UDP transmission status in the statistics page
GUI Improved: Added uTP external port monitoring information to the statistics page
GUI Improved: In expert mode, add the local external IP: utp-port obtained through PEX as a separate line to the peer list for diagnosis, but do not initiate a connection to oneself
GUI Improved: When creating torrent files, prioritize using the DHT nodes filled in by the user, and later use the current active DHT nodes
GUI Bugfix: After reconnecting to the remote desktop, the display position of the traffic map panel toolbar is misaligned
GUI Bugfix: LSD countdown in tracker list is inaccurate when the number of tasks is large
GUI Bugfix: In expert mode, the Infohash display in the value list of DHT network is incorrect
GUI Bugfix: RSS auto downloader does not use the default download directory for task tags when using RSS feed titles as task tags
Core Improved: Optimize the code for BT transmission encryption and decryption operations in worker threads, reducing CPU usage
Core Improved: Optimize the scheduling algorithm for initiating TCP connections, improve the processing speed of transferring pending queues to half open queues, and balance the handling of different connection types
Core Improved: Optimize the dynamic adjustment algorithm for the MTU of uTP packets at the sender end
Core Improved: Optimize uTP LEDBAT congestion control algorithm, reduce CPU usage, and improve upload speed
Core Improved: When BT task is connected to uTP, if there is no real interaction within 10 seconds after the complete metadata is sent, it will be disconnected
Core Improved: The maximum interval for tracker announcements has been changed to 180 minutes, with jitter of ±3 minutes
Core Improved: UDP tracker improves Connection ID timeout update and error handling
Core Improved: Improve the IP filter disconnection handling of BT protocol and long-term seeding protocol for TCP and UDP connections
Core Improved: Optimize DHT packet sending control to reduce the impact of high peak UDP packet rates and session counts on network devices
Core Improved: BT Handshake Extension Protocol adds yourport field, which returns the observed external uTP port of the other party when receiving an incoming uTP connection
Core Improved: After manually performing NAT type detection, record the detected external UDP ports for future use
Core Improved: When replying to DHT announce_peer messages, refer to the BEP42 format and return the request source IP: port observed by this node in the top-level IP field
Core Improved: When receiving DHT responses, process the locally visible UDP endpoint returned by the other party through the BEP42 IP field; Multiple DHT nodes need to cross confirm before acceptance, reducing the risk of a single malicious or erroneous node contaminating external uTP ports
Core Improved: When announcing one's external uTP port through PEX, data sources from BitComet extended handshake Yourport, PEX backhaul, and trusted DHT BEP42 backhaul can be used
Core Improved: When DHT replies to get_piers, attach nodes nodes
Core Improved: When DHT receives a reply from get_piers, it ignores the node distance and performs an additional extended query on the attached nodes
Core Improved: When DHT uses domain nodes for bootstrap, it immediately adds the node to the list after resolving the domain name, and then waits for the node to reply
Core Bugfix: When BT task disk cache reaches its limit and uploads to multiple peers, the disk read speed is much faster than the upload speed
Core Bugfix: When the number of TCP initiated connections is too high, there is packet loss on the TCP port
Core Bugfix: HTTP Tracker avoids repeatedly initiating connections when they are pending
Core Bugfix: Optimize DHT packet control and eliminate the delay of the first announcement when tasks start
Core Bugfix: After UDP Tracker Domain DNS resolve, sends request only to the first record when there are multiple records
Core Bugfix: DHT Tracker lacks the get_peers step when manually announcing
Core Bugfix: DHT should not send announcements to nodes that have not received tokens
WebUI: Optimizing pagination loading of task lists and file lists
WebUI: CPU usage statistics in traffic graph add categories of "BT transmission thread", "DHT thread", and "uTP thread"
WebUI: Add Options in Remote Access Page: Local client bypass authentication, whitelist clients bypass authentication
WebUI: Fixed the issue where information cannot be copied to the system clipboard when accessing pages via HTTP+IP
WebUI: Add the "Copy Download Link" command to the right-click menu of the file list
WebUI: Add uTP Port column to the peer list of BT task, hidden by default
