KtIrc/CHANGELOG

vNEXT (in development)

 * 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

v1.0.1

 * 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

 * 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

 * Added SourcedEvent interface for events that have a user source attached
 * Added ChannelJoinFailed event
 * Added ChannelMembershipAdjustment interface for events that concern
   users joining/leaving channels
 * Added missing user parameter to ModeChangedEvent

v0.10.3

 * Fixed multiple issues when receiving malformed input from the server:
   * Invalid server-time tags are now ignored and the current time used
   * PRIVMSGs, NOTICEs and TOPICs with no target/message are now ignored
   * CAPs with invalid or missing arguments are now ignored
   * Better handling for duplicate JOIN messages
   * Ignored messages are now logged more consistently

v0.10.2

 * Fix handling of multiple long lines sometimes dropping part of the line
 * Support lines with 8191 bytes of tags, as allowed by the message-tags spec
 * Fix a few more instances of occasional ConcurrentModificationExceptions

v0.10.1

 * Added NickChangeFailed event for when nicknames are in use, banned, etc
 * Added sendPart method
 * Fix occasional ConcurrentModificationException when adding state
 * (Internal) Moved message processors into their own package
 * (Internal) Added ExperimentalIrcClient interface for features not yet ready for release

v0.10.0

 * Batch start and end events are no longer included in BatchReceived events
 * 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)
   * send(command, arguments) is available if no tags are to be sent
   * the line is built automatically (with spaces/' :' added appropriately)
   * send(line) is deprecated and will be removed after v1.0.0
 * Add 'alwaysEchoMessages' behaviour that makes it easier to deal with servers
   that don't support the echo message capability
 * Added TargetedEvent, a subclass of IrcEvent, for all events that are
   targeted to a user or channel
 * (Internal) Added annotation to track removal of deprecated methods
 * (Internal) Migrate unit tests to use Mockk instead of Mockito

v0.9.0

 * 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)
   * IrcEvent.time is now deprecated but will remain until after v1.0.0.
   * Metadata now contains the message ID, if any.
     * ActionReceived.messageId and MessageReceived.messageId are now deprecated, to be removed after v1.0.0.
   * Metadata now contains the event's batch ID, if any.
 * Added support for batches
   * All events in a batch are buffered until the batch is finished
   * The events are then published together in a single `BatchReceived` event
 * Added support for CHGHOST messages
 * (Internal) Improve performance when the MessageHandler is finding a processor for a message
 * (Internal) Introduced event mutators
   * Event mutators are now responsible for handling changing events in response to state
     e.g. ChannelFanOutMutator creates Channel* events for global quits/nick changes/etc
   * Event handlers now just handle events, and don't return anything
