BREAKING CHANGES

• state-fn now needs to return a map, where the fresh component state is expected under the :state key. In addition, an optional :shutdown-fn can be specified, which will be called when the component is shutdown or restarted. This is for example useful when resources such as web servers or database connections need to be shut down.

[0.3.15] - 2015-12-03

Changed

• documentation; dependency upgrades; Clojure 1.8.0-RC3 in sample

• version bumps, including core.async v0.2.371

[0.3.7] - 2015-10-26

Changed

• fix for exception when putting too many messages at once

[0.3.6] - 2015-10-15

Changed

[0.3.1] - 2015-10-13

Changed

[0.2.31] - 2015-10-12

[0.2.30] - 2015-09-23

Changed

• version bumps

[0.2.29] - 2015-08-29

[0.2.27] - 2015-08-21

Changed

• dependency updates & web server options

[0.2.26] - 2015-08-10

Changed

• Immutant-web instead of http-kit: as far as open source projects go, http-kit does not look very healthy.
• Less logging: the log component is probably not very useful at all. There's no good reason not to use 'conventional' logging inside handler code. Being able to inspect input and output messages without recompile should greatly reduce the need for logging anyway.

[0.2.25] - 2015-08-08

Changed

• refactoring, more readable component namespace

[0.2.24] - 2015-08-06

Changed

• recording the sequence of handling components
• dependency bumps

[0.2.23] - 2015-08-06

Changed

• UUIDs sent as strings

[0.2.22] - 2015-08-05

Changed

• Only non-firehose messages are wrapped when putting on firehose channel

[0.2.21] - 2015-08-04

Changed

• messages that are sent between component started and system completely wired are kept

[0.2.20] - 2015-07-30

Changed

• Expose metadata explicitly in firehose messages

[0.2.19] - 2015-07-30

Changed

• Reagent components now support :lifecycle-callbacks parameter that can be used to attach React components' lifecycle methods such as :component-will-update.

[0.2.18] - 2015-07-28

Changed

• When a message is first emitted, a :tag UUID is attached to the metadata, which allows tracking a message on its way through the system. Also, a correlation UUID is attached, which uniquely marks an emitted message.
• The full sequence of components that a message passes through is recorded on the metadata.

[0.2.17] - 2015-07-23

Changed

• View components can call init-fn on initialization. This can for example be useful when attaching a watcher to the local state atom.

[0.2.16] - 2015-07-21

Changed

• no requirement for scheduler id, default is the keyword in the first position inside message to be sent
• switchboard prints component state for inspection when receiving [cmd/print-cmp-state cmp-id] message
• simplification of and documentation for route-handler

[0.2.15] - 2015-07-09

Changed

• minor rewrites after 'lein kibit'

[0.2.14] - 2015-07-09

Changed

• Documentation

[0.2.13] - 2015-07-08

Changed

• Reloadable components without modification, e.g. for use with Figwheel
• Specify components that can't be reloaded, e.g. WebSockets connection component

[0.2.10] - 2015-07-06

Changed

• Better error handling and logging in message handler loops
• Using aviso/pretty for exception logging in example

[0.2.9] - 2015-07-05

Changed

• Figwheel in example
• Publish state snapshot on reload

[0.2.8] - 2015-07-03

Changed

• Reader conditionals instead of the now-deprecated CLJX

[0.2.7] - 2015-07-01

Changed

• Clojure 1.7 final instead of release candidate
• observer component tweaks

[0.2.6] - 2015-06-24

Changed

• Custom state snapshot transformer function used in switchboard. With that, routing snapshots to server no longer fails. Minimal functionality, state snapshots from switchboard should include more information, not just component keys.
• Observer component feeds entirely off of messages on firehose; no need for subscribing to switchboard state.s

[0.2.5] - 2015-06-23

Changed

• Custom state snapshot function: allows stripping state of functions, channels and the like. Particularly useful in switchboard where state snapshots could otherwise not traverse the WebSockets connection between client and server.
• Should the full state with non-serializable values such as channels ever be needed, there could still be a message for retrieving the full state map.

[0.2.4] - 2015-06-19

Changed

• Enable handler maps inside UI components. This allows for UI components that are more independent and don't require an external store/state component. This feature can be useful for components that do not share any state with other components.
