## [0.3.16] - 2021-03-18
### Added
- New simulation code under `cmd/yggdrasilsim` (work-in-progress)
### Changed
- Multi-threading in the switch
- Swich lookups happen independently for each (incoming) peer connection, instead of being funneled to a single dedicated switch worker
- Packets are queued for each (outgoing) peer connection, instead of being handled by a single dedicated switch worker
- Queue logic rewritten
- Heap structure per peer that traffic is routed to, with one FIFO queue per traffic flow
- The total size of each heap is configured automatically (we basically queue packets until we think we're blocked on a socket write)
- When adding to a full heap, the oldest packet from the largest queue is dropped
- Packets are popped from the queue in FIFO order (oldest packet from among all queues in the heap) to prevent packet reordering at the session level
- Removed global `sync.Pool` of `[]byte`
- Local `sync.Pool`s are used in the hot loops, but not exported, to avoid memory corruption if libraries are reused by other projects
- This may increase allocations (and slightly reduce speed in CPU-bound benchmarks) when interacting with the tun/tap device, but traffic forwarded at the switch layer should be unaffected
- Upgrade dependencies
- Upgrade build to Go 1.16
### Fixed
- Fixed a bug where the connection listener could exit prematurely due to resoruce exhaustion (if e.g. too many connections were opened)
- Fixed DefaultIfName for OpenBSD (`/dev/tun0` -> `tun0`)
- Fixed an issue where a peer could sometimes never be added to the switch
- Fixed a goroutine leak that could occur if a peer with an open connection continued to spam additional connection attempts
