• Fixed documentation / bad links (#397)
• Removed a check which prevented alternative implementations of the group plugin (#394)
• Terraform plugin improvements on logical ID, private IP handling (#392, #395)

This release contains minor fixes since v0.3.0 that are necessary for an improved UX on working with plugins and templates:

This release contains bug fixes, API and schema changes, as well as a major reworking of the Swarm flavor plugin.

If you are vendoring Infrakit packages in your project, code change will be necessary because interface signatures have changed (see #371)

Highlights:

• New types introduced + SPI method signature changes to use plugin.Name and types.Any (#362, #363, #371)
• A new Label() method has been added to the Instance Plugin SPI (#371).
  • Updated implementations for file, terraform plugins
  • Added tests for file, terraform plugins.
• Multiple groups can now be specified in a JSON config for the manager (#368)
  • New commands: infrakit manager commit / inspect
  • Manager accepts JSON template, performs string interpolation.
• Plugin management improvement
  • New commands (infrakit plugin start / stop) (#367)
  • Configuration JSON schema changed to support different kinds of executors (e.g. os, docker-run). (#374)
• Templating engine improvements (#366, #373)
• Change to plugin handshake protocol. Handshake for version checking is performed at connection time, not per-call (#369) and as early as possible.
• Vagrant plugin improvement - real-time streaming of vagrant logging (#375)
• Swarm flavor plugin revamp (#376)
  • Instance startup init script now programmable via templates
  • Changed config schema and eliminated dependency on Docker connection parameters on plugin startup via CLI flags
  • A single commit of a configuration JSON template now provision multiple groups (e.g. managers and workers)

Highlights:

• Multiplexing plugin objects in a single RPC endpoint / instance types (#360, #364)
• Template engine + built-in functions; new template CLI (#353, #366)
• Plugin activation - os executor; new infrakit plugin start CLI (#356)
• Group plugin handles platform API throttling (#332)
• Publishing Infrakit binaries as Docker images (#339)
• New e2e tests (#355, #359)
• Golang API improvements (#362, #363)
• Manager plugin improvements (#354)

Highlights:

• The default group, instance, and flavor plugins golang API have been stabilized.
• Verb changes for the group plugin - #293
• Attachment supports resource types - #316
• RPC protocol now uses JSON-RPC 2.0 over HTTP - #310, #297
• API versioning handshake - #318
• High-availability - #283
• Better logging - #300
• More docs, better docs and code synchronization - #307
• Example Terraform plugin supports SoftLayer / IBM Bluemix - #321
