## [0.3.9] - 2019-09-27
|
||||||
|
### Added
|
||||||
|
- Yggdrasil will now complain more verbosely when a peer URI is incorrectly formatted
|
||||||
|
- Soft-shutdown methods have been added, allowing a node to shut down gracefully when terminated
|
||||||
|
- New multicast interval logic which sends multicast beacons more often when Yggdrasil is first started to increase the chance of finding nearby nodes quickly after startup
|
||||||
|
|
||||||
|
### Changed
|
||||||
|
- The switch now buffers packets more eagerly in an attempt to give the best link a chance to send, which appears to reduce packet reordering when crossing aggregate sets of peerings
|
||||||
|
- Substantial amounts of the codebase have been refactored to use the actor model, which should substantially reduce the chance of deadlocks
|
||||||
|
- Nonce tracking in sessions has been modified so that memory usage is reduced whilst still only allowing duplicate packets within a small window
|
||||||
|
- Soft-reconfiguration support has been simplified using new actor functions
|
||||||
|
- The garbage collector threshold has been adjusted for mobile builds
|
||||||
|
- The maximum queue size is now managed exclusively by the switch rather than by the core
|
||||||
|
|
||||||
|
### Fixed
|
||||||
|
- The broken `hjson-go` dependency which affected builds of the previous version has now been resolved in the module manifest
|
||||||
|
- Some minor memory leaks in the switch have been fixed, which improves memory usage on mobile builds
|
||||||
|
- A memory leak in the add-peer loop has been fixed
|
||||||
|
- The admin socket now reports the correct URI strings for SOCKS peers in `getPeers`
|
||||||
|
- A race condition when dialling a remote node by both the node address and routed prefix simultaneously has been fixed
|
||||||
|
- A race condition between the router and the dial code resulting in a panic has been fixed
|
||||||
|
- A panic which could occur when the TUN/TAP interface disappears (e.g. during soft-shutdown) has been fixed
|
||||||
|
- A bug in the semantic versioning script which accompanies Yggdrasil for builds has been fixed
|
||||||
|
- A panic which could occur when the TUN/TAP interface reads an undersized/corrupted packet has been fixed
|
||||||
|
|
||||||
|
### Removed
|
||||||
|
- A number of legacy debug functions have now been removed and a number of exported API functions are now better documented

### Fixed

- **Security vulnerability**: Address verification was not strict enough, which could result in a malicious session sending traffic with unexpected or spoofed source or destination addresses which Yggdrasil could fail to reject
|
- A deadlock was fixed in the session code which could result in Yggdrasil failing to pass traffic after some time
