Version numbers follow Semantic Versioning.

Unreleased

  • Breaking: Fixed a erroneous implementation of the IRCv3 tags: This crate now no longer differentiates between empty and missing IRCv3 tag values (e.g. @key is equivalent to @key=). The type of the IRCTags struct has changed to hold a HashMap<String, String> instead of a HashMap<String, Option<String>>.

    Where as re-stringifying messages with the above distinction was flawless before, this information is now intentionally discarded during parsing. This means @key= becomes @key if the message is parsed and re-stringified (This is the recommended and confirming way, according to the standard).

    See also: #186 and #196

  • Breaking: Removed ban(), unban(), timeout() and untimeout() since they are no longer supported by Twitch. They were previously deprecated in v4.1.0 (#197)

  • Breaking: Fixed typo in RoomStateMessage's follower mode (was follwers_only, is now followers_only. (#200)

  • Minor: Added support for reply-parent tags (#189)

  • Minor: Tokens in CredentialsPair and UserAccessToken are now redacted in their Debug output. Same applies to the client_secret in RefreshingLoginCredentials. (#199)

  • Minor: Added example demonstrating usage of metrics-collection feature as well as an exemplary grafana dashboard template. (#203, #208)

v5.0.1

  • Minor: Removed unused features from the chrono dependency (#185)
  • Bugfix: Upgraded dependencies to eliminate vulnerability in the webpki crate. (#193)

v5.0.0

  • Breaking: A lot of details regarding the metrics collection system have been reworked. (#160)
    • Switched from using the metrics crate to using the promtheus crate.
    • Usage of the new library and new config types now allows you to specify a Registry (from the prometheus crate) to register the metrics on, instead of being forced to use one global registry like with the metrics crate.
    • The config option metrics_identifier in the config has been replaced by a MetricsConfig enum, which now allows complete flexibility regarding what labels are added to the metrics. (Previously, only client => a_value_chosen_by_you could be added, and adding it was mandatory due to the API design I had chosen previously.)
    • This also means you can now specify any amount of additional key => value label pairs to be placed on the exported metrics. I imagine this to be useful to export any kind of metadata about your application/use-case.
    • The metrics have been renamed from twitch_irc_* to twitchirc_* to align with the prometheus naming conventions.
    • twitch_irc_reconnects has been renamed to twitchirc_connections_failed to better reflect what it actually counts.
    • Added twitchirc_connections_created as the obvious counterpart to aforementioned metric.
  • Breaking: Handle emote_sets as Strings since not all of them are in fact u64s (#162)
  • Breaking: Removed ChatClient::say_in_response and ChatClient::reply_to_privmsg in favour of a new API design (Chatclient::say_in_reply_to) which does the same thing as the previous functions, just with a sleeker API design. (#166)
  • Breaking: Removed support for parsing HOSTTARGET messages (Twitch has removed Host mode since 2022-10-03) (#183)
  • Minor: Added me and me_in_reply_to methods to send /me messages. (#170)
  • Minor: Implement Clone for RefreshingLoginCredentials. (#176)
  • Minor: Implement Eq for many structs. (#177)

v4.1.0

v4.0.0

  • Breaking: Updated metrics to version 0.18. (#146)
  • Breaking: Implement user login fetching via the API when using RefreshingLoginCredentials. (#144)
  • Breaking: It was possible to trip up the channel joinery logic of the client pretty good by joining channels with a comma in them. Added a basic validation step to TwitchIRCClient.login and TwitchIRCClient.set_wanted_channels to ensure channel names are in a sane format - these two functions now return a Result that you will have to handle in your code. The underlying used validation function is exported for use as twitch_irc::validate::validate_login. (#149, #154, #156)
  • Breaking: This library now no longer uses the log crate for logging. All logging is now done via tracing. This allows you to now differentiate log messages by async task, by connection, and if configured, even by client if your application is running multiple clients. A new configuration option has been introduced for this: config.tracing_identifier. (#151)
  • Breaking: Renamed the refreshing-token feature to refreshing-token-native-tls to reflect the fact that it pulls in the OS's native TLS library (e.g. OpenSSL/Schannel). Added the refreshing-token-rustls-native-roots and refreshing-token-rustls-webpki-roots feature flags to complement the other parts of the library where you can choose between the three options. (#153)
  • Minor: Implement Clone for RefreshingLoginCredentials (#143)
  • Minor: Added feature flag transport-ws-rustls-native-roots to allow websocket connections powered by rustls using the OS-native root certificates. (#146)
  • Minor: Updated some further dependencies:
    • async-tungstenite 0.13 -> 0.17
    • rustls-native-certs 0.5 -> 0.6
    • tokio-rustls 0.22 -> 0.23
    • tokio-util 0.6 -> 0.7
    • webpki-roots 0.21 -> 0.22

v3.0.1

  • Bugfix: Fixed FollowersOnlyMode enum not being exported from the crate. (#135)

v3.0.0

  • Breaking: Transports were refactored slightly:
    Renamed twitch_irc::TCPTransport to SecureTCPTransport, added PlainTCPTransport for plain-text IRC connections.
    Renamed twitch_irc::WSSTransport to SecureWSTransport, added PlainWSTransport for plain-text IRC-over-WebSocket-connections.
    Refactored feature flags: This crate used to only have the transport-tcp and transport-wss feature flags. The following is the new list of feature flags relevant to transports:

    • transport-tcp enables PlainTCPTransport
    • transport-tcp-native-tls enables SecureTCPTransport using OS-native TLS functionality (and using the root certificates configured in your operating system).
    • transport-tcp-rustls-native-roots enables SecureTCPTransport using rustls, but still using the root certificates configured in your operating system.
    • transport-tcp-rustls-webpki-roots enables SecureTCPTransport using rustls with root certificates provided by webpki-roots (Mozilla's root certificates). This is the most portable since it does not rely on OS-specific functionality.
    • transport-ws (notice this is now ws instead of wss) - Enables PlainWSTransport
    • transport-ws-native-tls - Enables SecureWSTransport using native TLS (same as above)
    • transport-ws-rustls-webpki-roots - Enables SecureWSTransport using rustls with Mozilla's root certificates (same as above)

    Some accompanying items have also been made pub in the crate.

  • Breaking: Updated metrics to version 0.16.

  • Minor: Added timeout, untimeout, ban and unban methods to TwitchIRCClient (#110)

  • Minor: Added serde feature, adding the ability to serialize or deserialize the command structs using serde. (#120)

  • Minor: Metrics are no longer initialized, undoing the change introduced with v2.2.0 (#129)

v2.2.0

  • Bugfix: Fixed fields on UserAccessToken being all private, preventing library users from constructing the type (as part of the RefreshingLoginCredentials system). (#101, #103)
  • Reduce the amount of dependencies used. (#96)
  • Update metrics dependency to v0.14. Metrics are now registered with a description when the client is created. (#97)
  • Chore: Fix all the clippy warnings in the project.

v2.1.0

  • Minor: Added say_in_response and reply_to_privmsg methods to TwitchIRCClient (#84)

v2.0.0

  • Updates to tokio v1.0 (#75)

v1.0.0

  • Reverts to tokio v0.2 (#56)

v0.3.0

This release was later yanked because the tokio 0.3 upgrade was incomplete. Multiple versions of tokio were specified in the dependencies.

  • Minor: Updated to tokio v0.3. (#48)
  • Minor: Added a new config option to specify connect timeout. (#48)
  • Bugfix: Fixed client sporadically locking up as a result of the TLS connection setup not having a timeout. (#48)

v0.2.1

  • Bugfix: Fixed compile error when default features were disabled. (#21)

v0.2.0

  • Breaking: Renamed Error::ClientClosed to Error::RemoteUnexpectedlyClosedConnection to clarify intent
  • Minor: Added event_id to UserNoticeMessage to allow parsing undocumented types of events.
  • Minor: Client previously returned Error::ClientClosed in cases where that error wasnt appropriate (when the client was closed due to some other error that had occurred previously) - the error that caused a connection to close down is now kept as long as needed and every time the connection is used after this error, a clone of the original cause is returned.
  • Bugfix: Fixed UserStateMessage not being exported (pub).

v0.1.2

  • Bugfix: Include all features in the documentation on docs.rs.

v0.1.1

  • Minor: Gracefully work around a Twitch bug regarding emote indices.
  • Bugfix: Fixed possible issue with messages getting sent out in the wrong order after connection setup.

v0.1.0

This was the initial release.
