• Bug fix release.

Notable changes in this release:

• New "opercmds" plugin:
  • This merges some functionality from the bots plugin, but also adds new commands such as jupe, kill, topic, and checkban.
• New "changehost" plugin - Automated configurable vHost setting on connect.
• Some core changes will break protocol modules and plugins written for older PyLink versions:
  • Some functions have been renamed:
    • utils.nickToUid(irc, nick) -> irc.nickToUid(nick)
    • utils.isInternalClient(irc, uid) -> irc.isInternalClient(uid)
    • utils.isInternalServer(irc, uid) -> irc.isInternalServer(uid)
    • utils.clientToServer(irc, uid) -> utils.getServer(uid)
    • utils.getProtoModule(...) -> utils.getProtocolModule(...)
  • Protocol specification is rewritten, with "Client" and "Server" dropped from the suffix of most outgoing commands: see acdd7db...2fd0a8a.
• exec plugin: add inject and raw commands (4e7396b).
• exec plugin: support newline (and other) escapes in exec (375dbe8).
• protocols: allow changing remote users' hosts in updateClient (741fed9).
• Speed up and clean up shutdown sequence, fixing hangs due to sockets not shutting down cleanly (#152).
• protocols/unreal: Support cloaking with user mode +x (#136).
• Various bug fixes - see 0.5-dev...0.6.0-dev for a full diff.

The "We're getting somewhere..." release.

Changes

• Bug fixes, all the bug fixes.

Core

• Support IPv6 connections in config.
• The offending hook data is now logged whenever a hook function errors, for more convenient debugging.
• Add sanity checks for autoconnect - delay has to be at least 1 second now, to prevent connect floods that go on without any delay in between!
• Add irc.reply() to send command replies to callers in the right context (channel or PM).
• More base commands are in coreplugin instead of commands.py now, making the latter reloadable without restart.
• Don't crash when REHASH loads a config file that's invalid.
• utils: Replace imp (deprecated) with importlib.

Plugins

• commands: Add a command to set log level (#124).
• commands: Update irc.botdata (bot: data in config) in REHASH.
• fantasy: Support nick prefixes (e.g. PyLink: help), along with a configurable prefix.

Protocols

• protocols/TS6: Fix SQUIT handling and introduction of SID-less servers (i.e. atheme's /os JUPE) (#119)
• protocols/unreal: Add (experimental) support for UnrealIRCd 4.0.x!
• plugins: More complete INFO logging: plugin loading/unloading, unknown commands called, successful operups
