• Add walk built-in function to recursively process nested documents
• Refactor Policy API response representations based on usage

v0.5.5

This release adds Diagnostics support to the server. This greatly improves OPA's debuggability when deployed as a daemon.

• Add watch package for watching changes to queries
• Add dependencies package to perform dependency analysis on ASTs

v0.5.2

Fixes

• Fix mobile view navigation bug
• Fix panic in compiler from concurrent map writes (#379
• Fix ambiguous syntax around body and set comprehensions (#377)

Miscellaneous

• Add support for set and object comprehensions
• Add support for system.main policy in server
• Add transaction support in rego package
• Improve type checking error messages
• Format REPL modules before printing them

v0.5.1

Fixes

• Correct opa fmt panic on missing files
• Fix minor site issues

Miscellaneous

• Add rego examples with input and compiler
• Add support for query cancellation

v0.5.0

User Functions

OPA now supports user-defined functions that have the same semantics as built-in
functions. This allows policy authors to quickly define reusable pieces of logic
in Rego without overloading the input document or thinking about variable
safety.

Storage Improvements

The storage layer has been improved to support single-writer/multiple-reader
concurrency. The storage interfaces have been simplified in the process. Users
can rely on https://godoc.org/github.com/open-policy-agent/opa/storage/inmem in
place of the old storage package.

Website Refresh

The website has been redesigned and the documentation has been ported over to
GitBook.

opa check and opa fmt

OPA supports two new commands that check and format policies. Check out opa help for more information.

Miscellaneous

• Add YAML serialization built-ins
• Add time built-ins

Fixes

• Fixed incorrect source locations on refs and manually constructed terms. All
  term locations should be set correctly now.
• Fixed evaluation bug that caused partial sets and partial objects to be
  undefined in some cases.
