v2.3.1a - 2019.10.14

This release fixes some smaller bugs and polishes off some rougher edges related to the chat improvements of the major v2.3.0 update but it also introduces two important new features namely the ability to configure the NLU interpretation chain of SEPIA and the option to add a custom NLU server to it that integrates seamlessly with the dialog management of SEPIA. There is an example given in the updated SDK that demonstrates how you can use the new SEPIA Python bridge (an early stage, lightweight Python server written with FastAPI) to upgrade your own services with custom Python code.
As usual there are plenty of other tweaks and optimizations so check out the full patch notes below:

Release notes

Updated client to v0.19.1:

  • Custom-buttons (defined via Teach-UI) work properly now in group-chats
  • Show a colored bell in AO mode to indicate 'you have a message in another channel'
  • Fixed some bugs related to channel-history feature, e.g. a few seconds scrolling-lock and missing/wrong day tags in chat
  • Improved audio-events tracking and handling in connection to 'hey SEPIA' wake-word
  • Added option to allow/prevent wake-word while music is playing (default: prevent, to avoid audio artifacts in some mobile clients)
  • Improved audio recorder performance and stability and fixed dynamic downsampling
  • Fixed some issues with YouTube player (sometimes 'pause music' wasn't working)
  • Added 'env' URL parameter to be able to set custom value for 'environment' variable (client info sent to server)
  • Fixed deprecated code in iOS audio processing to make build process work again (iOS 12.4, Swift 5 - native ASR still broken, but restored open-source ASR support)
  • Improved some error messages after failed login
  • Prevent multiple queued follow-up messages of same 'type' (only one will show)
  • Prevent chat names that look like user IDs to prevent accidental private messages to wrong receiver
  • Prevent auto-scrolling of chat when hidden channel-status message was added
  • Updated jquery to 3.4.1
  • Added library for voice-activity-detection (VAD, though it is not used yet)

Updated Control-HUB (admin-tools) to v1.2.2:

  • Updated smart home settings with new device and room options
  • Implemented remote-action on 'assistant' page
  • Added info message for new temporary 'login blocked' feature and fixed a bug with 'new login'
  • Updated jquery to 3.4.1

Updated Assist-server to v2.3.1:

  • Made NLU interpretation-chain configurable via properties file entry 'nlu_interpretation_chain'
  • Introduced 'getWebApiResult' as new interpretation-step to easily integrate different NLU servers (example chain entry for SEPIA Python bridge: getPersonalCommand, WEB:http://127.0.0.1:20731/nlu/get_nlu_result, ...)
  • Introduced abstract class 'WebApiParameter' to easily integrate custom parameter handlers that use different NLU servers
  • Improved JSON import/export methods for 'NluInput', 'NluResult' and 'User' classes and added optional 'custom_data' fields to better serve new web API NLU options
  • Introduced 'addCustomTriggerSentence' variations in 'ServiceInfo' to support predefined parameters (raw, normalized or extracted)
  • Introduced optional input tags '<i_raw>', '<i_norm>' and '<i_ext>' to 'Interview' module to control how a predefined parameter should be handled
  • Updated 'SmartDevice' and 'Room' parameters with new types (tv, fridge, oven, office, ...)
  • Updated news outlets with 'Hackaday' RSS feed
  • NLU tweaks ("pause music", "switch to german", ...)
  • Fixed and improved 'remote-action' endpoint
  • Added security feature to natively protect selected accounts from brute-force attacks by blocking login temporarily after too many failed attempts. Add accounts via properties file entry 'protected_accounts_list'
  • Added option to deactivate security policy and sandbox via cmd arguments 'nosecuritypolicy' and 'nosandbox'
  • Code clean-ups
