Release v0.8.0

[jshlbrd]

Hey folks, this is our announcement for the release of Substation v0.8.0! 🎉

We Have A New Look

You'll notice that our READMEs received an overhaul -- our documentation moved to https://substation.readme.io/ and includes an overview of the project, detailed guides on each component, and recipes that users can follow along with to use the system.

Resetting the Public API

The focus of this release is breaking the public API so that the project is easier for the team to maintain. This includes:

• Refactoring all public facing components (processors, conditions, sinks, transforms) to be internally private and only accessible by public interfaces and factory methods
• Refactoring the structure of processors and conditions to be more modular
• Refactoring our Jsonnet functions into a single monolithic library

These changes were necessary for two reasons:

1. Limiting the surface area of our public API -- this makes the code easier to maintain and resulted in no loss of functionality from the previous version
2. Increasing our focus on using Jsonnet as the interface for building configurations -- the system's components (conditions, processors) were refactored in a way that makes it easier for users to simplify and create configurations as code

Other Changes

The reset also made these changes:

• and, or, nand, and nor operators were removed and renamed to all, any, and none
  • all == and
  • any == or
  • none == nand
• concat processor is now named join
• math processor now supports floats
• Internal JSON processing package now supports raw arrays
