Cog 0.14.0

Enhancements

• New Template Engine #876
  • Cog's previous Mustache-based template engine, fumanchu, has been deprecated and replaced
    by greenbar. The combination of Cog's new chat API (released in 0.13) and Greenbar allows
    Cog to render a single template across multiple providers and preserve the majority of formatting.
• Added a -dev flag to Relay's CLI #950
  • We've added a development mode to Relay to simplify bundle development. Starting a Relay with -dev causes Relay to
    re-pull any Docker images associated with installed command bundles on each pipeline execution. This should simplify
    iterating command development.
• Improved presentation of bundle and command help #658
• Introduced new bundle config version 4 which adds documentation structure
  used by help command and reorganized template definitions. Also bundle
  descriptions are now required. spanner #76

Bug Fixes

• Return better error message for invalid dynamic configurations #867
• Update Docker installation documentation #932
• Documented Relay's backoff & retry behavior when disconnected #935

Cog 0.13.0

Enhancements

• New chat API #873, #925
  • The API Cog uses to interop with various chat networks has been thoroughly revamped. A temporary side-effect of this work
    is the removal of HipChat and IRC support. We expect to restore support for both of these chat networks in an upcoming
    release.

Command bundles

• pagerduty NEW
  • Repo: cogcmd/pagerduty
• pingdom NEW
  • Repo: cogcmd/pingdom

Bug Fixes

• Multi commands run slowly #677
  • Optimized Relay's Docker integration:
    • Containers are cached and reused for the duration of a command
      pipeline. Doing so reduces worst case Docker container creation
      from O(N * I * R) to O(N * R) where N is the number of pipeline
      stages, I is the number of command invocations per stage, and R
      is the number of Relays able to run the command.
    • Implemented a custom streaming interface on top of Docker's
      hijacked connection API further reducing the number of Docker
      API calls required per command invocation.
  • Internal testing has shown these optimizations reduce execution
    times for Docker-based commands by 50 - 70%.
• Fix Relay's JSON handling: Don't coerce large integers into
  scientific notation #768
• HipChat can't execute Relay-mediated commands #770
