v1.1.0

• Bug fix for default rule probability in Envoy config generation. (PR#552)

• Bug fix for TLS validation logic and Envoy config generation. (PR#549)

• TCP proxy support added to sidecar. (PR#548)

v1.0.0

• Switched Amalgam8 sidecar to use Envoy proxy from Lyft. (https://github.com/lyft/envoy)

• Support for HTTP/2, gRPC proxying (downstream and upstream).

• Support for gRPC bridging over HTTP/1.1.

• Support for configuring circuit breakers, bulkheads, timeouts, retries.

• Support for different load balancing algorithms (round robin, least conn, random). (PR#494)

• Deeper integration with Kubernetes: rules are now stored as third party resources. (PR#534)

• A fully revamped Go based cross platform CLI (a8ctl). (PR#396)

• Assorted bug fixes.

• NOTE: breaking changes:

  • Removed the bulk set API. (PR#537)
  • Removed a8ctl service-list command. (PR#536)
  • Removed a8ctl traffic-set, traffic-step, and traffic-abort commands. (PR#535)

v0.4.2

• Bug fix for sidecar proxy host header propagation logic. (PR#384)
• Bug fix for zombie process clean up in supervised applications. (PR#377)

v0.4.1

• Sidecar now supports TCP and command health checks. (PR#350)
• Sidecar now supports DNS queries for a specified domain. DNS queries for other domains will be forwarded to upstream DNS servers. (PR#328)
• Sidecar --supervise flag has been deprecated.
• Sidecar now supports supervision of multiple processes. (PR#349)
• Sidecar now logs the source IP address in the NGINX access logs. (PR#362)
• Fixed an issue in the controller that resulted in IDs not being returned on rule creation via the API. (PR#352)
• Updated to Go 1.7.1. (PR#345)

v0.4.0

• Sidecars now support HTTP health checks. The health check endpoint can be provided as part of the sidecar configuration file. When the application fails to respond to a health check, it is unregistered from the service registry, causing the instance to be removed from the load balancing pool of other sidecars upon the next refresh.
• A special CLI mode for the a8sidecar binary that allows users to view the state inside the sidecar. (PR#335)
• Filebeat is no longer installed/configured/managed by the sidecar. It is the user's responsibility to aggregate the sidecar's nginx access logs through a log management system of their choice.
• Minor performance optimizations to the Lua code in the sidecar and bug fixes. Timeout support is currently disabled. Specifying timeouts in the rules will not have any effect. (PR#334)
• Registry now supports Eureka remote catalog, similar to Kubernetes catalog. Service registration info in Eureka will now be synced with the Amalgam8 service registry automatically. (PR#247)
• Eureka metadata tags are automatically translated into Amalgam8 instance tags in the service registry.
• Optimizations to the redis operations used in registry code
• The bookinfo example application is now a polyglot application, composed of services written in Java, Ruby, and Python.
• Simplification of the demo scripts: consolidate into fewer files and eliminate unnecessary scripts.
• All documentation has been moved to https://amalgam8.io/docs/

v0.3.1

0.3.1 (September 20, 2016)

• Amalgam8 nginx configuration files in the sidecar is now split into
  multiple files. Amalgam8 specific code has been abstracted away into
  separate files, and user-customizable part is now confined to location
  blocks in amalgam8-services.conf (PR#278)
• Fixed invalid DNS config in kubernetes config that caused code compiled
  with Go 1.7.1 to fail (PR#280).
• Fixed bug in sidecar that caused HTTP 500 when version cookie did not
  match any backend in the route list (PR#271).
• Fixed bugs in bluemix deployment scripts and updated READMEs to point to
  the correct version of Bluemix CLI
  (PR#275 and
  PR#279).

v0.3.0

0.3.0 (September 12, 2016)

• The controller API has been overhauled to support a wider range of routing and fault injection rules.
• The dependency on Kafka has been removed from controller and sidecar.
• Sidecar now polls controller for rule changes and registry for service instance changes.
• Controller and Registry now have support for Redis persistent storage.
• NGINX Lua code has been overhauled to support the new rules API format from controller.
• Options for sidecar to proxy, register, and log now default to false.
• The default controller port is now 8080 instead of 6379.
• A8_SERVICE is now in the form of <service_name>:<tag1>,<tag2>,...,<tagN>
  where <tagN> can be a version number or any other tag. Sidecar will register
  with registry using these tags and rules can be defined to target services
