release notes

v0.59.0
This release adds tooling to help prepare existing policies for the upcoming OPA 1.0 release.

It also contains a mix of improvements, bugfixes and security fixes for third-party libraries.

NOTES:

All published OPA images now run with a non-root uid/gid. The uid:gid is set to 1000:1000 for all images. As a result

there is no longer a need for the -rootless image variant and hence it will not be published as part of future releases.

This change is in line with container security best practices. OPA can still be run with root privileges by explicitly setting the user,

either with the --user argument for docker run, or by specifying the securityContext in the Kubernetes Pod specification.


Rego v1
The upcoming release of OPA 1.0, which will be released at a future date, will introduce breaking changes to the Rego language. Most notably:

the keywords that currently must be imported through import future.keywords into a module before use will be part of the Rego language by default, without the need to first import them.
the if keyword will be required before the body of a rule.
the contains keyword will be required when declaring a multi-value rule (partial set rule).
deprecated built-in functions will be removed.

This current release (0.59.0) introduces a new --rego-v1 flag to the opa fmt and opa check commands to facilitate the transition of existing policies to be compatible with the 1.0 syntax.
When used with opa fmt, the --rego-v1 flag will format the module(s) according to the new Rego syntax in OPA 1.0.

Formatted modules are compatible with both the current version of OPA and 1.0.

Modules using deprecated built-ins will terminate formatting with an error. Future versions of OPA will support rewriting applicable function calls with equivalent Rego compatible with 1.0.
When used with opa check, the --rego-v1 flag will check that the modules are compatible with both the current version of OPA and 1.0.
