Release 1.9

Release 1.9 was published to Maven Central on December 14th, 2019.

Major points of this release are:

• improving throughput and cutting down on memory usage by implementing so-called “direct” I/O and better block request pipelining
• improving peer lookup and connectivity by figuring out which connections are duplicate and eliminating those
• allowing to create private DHTs within non-public networks (previously all nodes had to have public Internet address)

Bug Fixes/Improvements:

• onTorrentStarted called twice #117
• Add new onMetadataAvailable event (fired after torrent’s metadata has been fetched)
• Allow cookie to be missing in the LSD announce message
• Make sure outgoing messages are never dropped
• Continuous piece assignments (better request pipelining)
• Direct I/O
• Add configuration option for the number of outstanding requests
• Add configuration option for send/receive buffer size
• Add CLI parameter for DHT port
• Allow bogon addresses, when using private DHT
• Reliably eliminate duplicate peer connections and self connections
