v0.5.12

Fixes

• Fix eval of objects/sets containing vars (#505)
• Fix REPL printing of generated vars

v0.5.11

This release includes a backwards incompatible change to the io.jwt.decode built-in function. The built-in function used to return three output values as separate arguments to the built-in. The function now returns a single output value that represents the three values inside an array. Use:

io.jwt.decode(str, [hdr, payload, sig])

Instead of:

io.jwt.decode(str, hdr, payload, sig)

Also, this release contains backwards incompatible changes to the topdown package. The new version of the topdown package has removed some helper functions, however, the usage pattern is the same as before. See https://godoc.org/github.com/open-policy-agent/opa/topdown#example-Query-Iter for examples on how to use new version of the package.

Fixes

v0.5.7

This release adds a new test subcommand to OPA. The test subcommand enables policy unit testing. The unit tests are expressed as rules containing assertions over test data. The test subcommand provides a test runner that automatically discovers and executes these test rules. See opa test --help for examples.

Fixes

• Fix type error marshalling bug (#391)
• Fix type inference bug (#381)
