CHANGELOG.md

v2.0.1 (pending)

Initial release of libmudtelnet - a fork of libtelnet-rs.

Bug fixes

• A SE byte that isn't preceded by IAC is now properly handled as a normal byte during Telnet subnegotiation processing.
• Fixed a panic when Telnet option code 0xFF is negotiated, and a truncated subnegotiation (e.g. IAC SB IAC SE) is received.
• Multiple escaped IAC bytes (e.g. IAC IAC IAC IAC) are now properly unescaped (e.g. IAC IAC) instead of truncated (e.g. IAC).

Features

• Many API types now derive helpful traits (Debug, Eq, etc.).
• An optional arbitrary crate feature is now available to enable generating arbitrary event::TelnetIAC, event::TelnetNegotiation and event::TelnetSubnegotiation instances for testing.

Misc

• CI improvements.
• Fuzz testing.
• Simple benchmarking.
• Small performance and safety improvements (avoiding direct indexing, etc.).

v2.0.0

As of version 2.0, libtelnet_rs has switched over to using the bytes crate.

With this change, the method signatures for most methods that return Vec<u8> now return Bytes instead.

For most situations where a Vec<u8> would be required, the returned value can simply be changed to utilize Bytes::to_vec().

To make usage of the new dependency a little bit easier, it is also re-exported as libtelnet_rs::bytes.
