1. Optimize: drop TCP timeout and unnecessary SetKeepAlive (#29) @database64128
2. Fixed: panic when reload
3. Fixed: reserve servers with any upstream error (#28)

Thanks @database64128

1. Added flag to suppress timestamps in log. #22
2. Include client address in error messages of failed relay attempts. #23
3. Concurrently pull from all upstreams. #24
4. Bumped to Go1.17 and added darwin-arm64 and windows-arm64 binary. #27

Bug Fix

Fixed A Memory Leaking Problem

Optimize

• Switched fixed length LRU to fixed timeout LRU (#14)
• When reloading, remain those servers whose upstream pull conf was with net error (#16)
• Added systemd-timer integration (#15)
• Use go1.16 by default.

Feature

• Support hot-reload configuration: systemctl reload mmp-go or kill -USR1 <PID> #9
• Support pull outline configure by API #7

Optimize

• Speed up UDP packet auth in the failure situation #5

optimize:

• Change default UDP NAT timeout from 2 minutes to 3 minutes (refer to openWRT).
• Set TCP timeout to 7440 seconds (refer to openWRT).
• Speed up auth by adding buffer pool to lrulist.
• Lower memory consumption by selecting appropriate buffer size for UDP connection according to the MTU of the interface where connection from.
• Lower CPU consumption by auth only the first UDP packet.
• Switch go version to 1.16beta1 to avoid negative memory release strategy of GC #4. Thanks to @kslr

Fix

• Fixed a problem that cannot choose proper timeout for DNS query packet.
• Fixed a problem that goroutine leak. Thanks to @Ducksoft
• Fixed a vulnerability of malicious packet causing crash.

• feature: outline upstraem support link of shadowbox_config file. #2
• optimize: regard upstream error as warning
• optimize(outline): more detailed error log
• optimize(udp): udp memory occupation and efficiency

mmp-go

Mega Multiplexer, a single port multi-service relay for shadowsocks.
中转机单端口转发多台shadowsocks服务器。

Support pure AEAD methods shadowsocks based on both TCP and UDP.

Support automatically pull server configure from outline upstream by SSH.
