Znote AAC 2.0-alpha

Branch: v2
This is a pre-release, intended for TFS 1.4+ users.

The purpose of this branch is to server as code cleanup, and strip distro compatibility for anything below TFS 1.4. I want to refactor some code, try to get Znote AAC a bit more lightweight. Remove single-use functions from globally included function files etc.

TFS 1.4 (protocol 10.98)
Nekiro's downgrades based on TFS 1.4 (7.72, 8.0, 8.6)
TFS 1.5+ (protocol 12)

OTBR team has their own protocol 12 servers based on TFS 1.3 (which is older), if you run any server that is based on something older than TFS 1.4, use Znote AAC 1.6 instead of this release.

Znote AAC 1.6

Version 1 series of Znote AAC aims to be multi-distro legacy compatible, and has support for these versions:

TFS 0.2.13+ (Since initial release)
TFS 0.3.6+ (Since Znote AAC 1.2)
TFS 1.2+ (Since Znote AAC 1.5)
TFS 1.3 (Since Znote AAC 1.6).

Many distributions based on these are also working, but some bugs may occur. We have old distributions running protocol 7.4 running Znote AAC, as well as newer distributions for protocol 12.

For TFS 1.4+, especially TFS 1.5 with protocol 12 support, please refer to version 2.0. https://github.com/Znote/ZnoteAAC/tree/v2.
