= Changelog

== Next version (in development)
* No changes yet

== v1.1.0 (2019-03-13)

* Away support:
** Added sendAway() method
** Added UserAway event and fanned-out ChannelAway
** Away message is now updated in the UserState
* Added IrcClient.localUser property, returning the local User
* Deprecated ServerState.localNickname in favour of localUser.
* (Internal) improved the way byte buffers are used to
  reduce array copying and clean up code
* (Internal) Converted README, LICENCE and CHANGELOG to Asciidoc.

== v1.0.1 (2019-03-10)

* Fixed issue with very long packets not fitting in buffers
  after TLS decryption.
* Improved error message when IrcClient.connect() is called
  while already connected
* Made IrcClient.disconnect() block until the disconnect has
  been processed. This will be a very short period of time,
  and allows callers to immediately call connect() again
  afterwards if they wish
* Fixed various issues with disconnecting TLS connections
  not behaving correctly

== v1.0.0 (2019-03-09)

* Replaced Ktor dependency with custom socket handling, which fixes
  fatal issue when connecting to servers over TLS that request a
  client certificate.
* Added NicknameChangeRequired event for the case when a nickname is
  not allowed during connection and *MUST* be changed
* BREAKING: Added 'PreferIPv6' behaviour config, defaulting to true.
  With this configuration KtIrc will try to use IPv6 if the server
  publishes AAAA records.
* BREAKING: Default port is now 6697, TLS is enabled by default

== v0.11.0 (2019-03-06)

* Added SourcedEvent interface for events that have a user source attached

  users joining/leaving channels

* Batches now expose complete metadata from their start event
* Added support for labelled-replies capability and label message tags
* Added support for message-tags capability after it moved from draft
* Added new methods for sending raw lines to the IRC server
** send(tagMap(...), command, arguments) replaces send(line)

  that don't support the echo message capability

* Improve DSL for creating an IrcClient to allow parameters to be passed to server and profile
  e.g. IrcClient { server("irc.example.com", 6667) }
* Add behaviour options
** requestModesOnJoin - automatically sends a MODE request when joining a channel
* Events now have a `metadata` property instead of a `time` (and time is available in metadata)
