This release includes changes to the evaluator and modules experiments, as well as a number of other improvements and fixes.
Evaluator
Following the introduction of the new evaluator experiment in v0.8.0-alpha.2 via CUE_EXPERIMENT=evalv3, this release includes a number of fixes to known bugs in the new evaluator, as well as significant work towards supporting the new evaluator experiment via the Go API and not just cmd/cue.
Subscribe to the Performance umbrella issue for updates, and see the Evaluator Roadmap project for the planned work ahead.
Modules
CL 1194090 adds the --dry-run, --json, and --out flags to cue mod publish to inspect what would be published as part of a module version.
CL 1194106 adds the cue mod resolve command to show how a module path resolves to a registry in the form of an OCI reference.
As a reminder, the ongoing and planned work can be seen in the Modules Roadmap, and we continue to hold regular Modules feedback sessions.
Go API
CL 1193759 teaches cue/format to collapse empty lists and structs to a single line for consistent formatting.
Builtins
CL 1193690 fixes math.MultipleOf as it had an incorrect implementation which could easily return bad results.
cmd/cue
CL 1193778 adds a cue fmt --diff flag which displays diffs instead of updating files.
CL 1193934 improves cue fmt so that it does not write to files on disk which are already well formatted.
