ChangeLog

29 December 2016, build 158

I forgot to update this in a while, so this is a quite big changelog entry.

I got the first major code contributions by other developers, so from now on the changelog entries will be split by author. It may also have a header like this one in which it will contain a short summary or a message from the author.

Special thanks to Hugo Rosnet, who contributed a lot of code that implemented a number of major features, helped me with multiple code reviews and kept me motivated enough to constantly work on this project.

Also thanks to Jay Wineinger who contributed a non-trivial piece of code, and to the other folks who contributed documentation, raised or discussed various Github issues.

~Cristian

14 November 2016, build 79

Major, breaking compatibility, packaging update: now using eawsy/aws-lambda-go for packaging of the Lambda function

  • Switch to the golang-native eawsy/aws-lambda-go for packaging of the Lambda function code.
  • This is a breaking change, updating already running CloudFormation stacks will also need a template update.
  • Add versioning for the CloudFormation template.
  • Buildsystem updates (both on Makefile and Travis CI configuration).
  • Change build dependencies: now building Lambda code in Docker, use wget instead of curl in order not to download data unnecessarily.
  • Remove the Python Lambda wrapper, it is no longer needed.
  • Start using go-bindata for shipping static files, instead of packaging them in the Lambda zip file.
  • Introduce a configuration object for the main functionality, not in use yet.
  • Documentation updates and better formatting.
