## [0.3.8] - 2019-08-21
### Changed
- Yggdrasil can now send multiple packets from the switch at once, which results in improved throughput with smaller packets or lower MTUs
- Performance has been slightly improved by not allocating cancellations where not necessary
- Crypto-key routing options have been renamed for clarity
- `IPv4Sources` is now named `IPv4LocalSubnets`
- `IPv6Sources` is now named `IPv6LocalSubnets`
- `IPv4Destinations` is now named `IPv4RemoteSubnets`
- `IPv6Destinations` is now named `IPv6RemoteSubnets`
- The old option names will continue to be accepted by the configuration parser for now but may not be indefinitely
- When presented with multiple paths between two nodes, the switch now prefers the most recently used port when possible instead of the least recently used, helping to reduce packet reordering
- New nonce tracking should help to reduce the number of packets dropped as a result of multiple/aggregate paths or congestion control in the switch
### 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
- Versions `0.3.6` and `0.3.7` are vulnerable - users of these versions should upgrade as soon as possible
- Versions `0.3.5` and earlier are not affected
- A deadlock was fixed in the session code which could result in Yggdrasil failing to pass traffic after some time
## [0.3.7] - 2019-08-18
### Changed
- The switch should now forward packets along a single path more consistently in cases where congestion is low and multiple equal-length paths exist, which should improve stability and result in fewer out-of-order packets

## Project Status
The project is currently in early stages but it is being actively developed. We have recently released [version 0.3.7](changelog.md) and are still regularly working on updates.
The project is currently in early stages but it is being actively developed. We have recently released [version 0.3.8](changelog.md) and are still regularly working on updates.
A small number of users have been using and stress-testing Yggdrasil quite heavily for a number of purposes, including but not limited to secure remote access (SSH and VNC), access to Matrix, Jabber and IRC servers and even some video streams, large file transfers and performance tests. We have a number of [internal services](services.md) available, contributed and operated by the community.
