This release fixes many bugs in the new evaluator, enables the embedding experiment by default, and further improves JSON Schema support.
Changes which may break some users are marked below with: ⚠️
Evaluator
CLs 1204365, 1205361, and 1205363 fix a number of closedness issues in the new evaluator, which were spotted thanks to user reports and Unity testing.
CLs 1204490, 1205368, and 1205368 resolve a number of significant performance issues spotted in the new evaluator.
CL 1205861 enables the Embedding proposal via CUE_EXPERIMENT=embed by default, now that the proposal has been moved to a "likely accept" state for v0.12.
CL 1204491 introduces CUE_DEBUG=openinline, enabled by default, which emulates the old evaluator's incorrect closedness behavior in some edge cases. This should help the transition towards the new evaluator, and allow us to fix the behavior of these edge cases in future CUE releases.
CL 1204608 introduces CUE_DEBUG=sortfields which sorts all struct fields lexicographically. This replaces CUE_DEBUG_SORT_ARCS=1, which did not work with the new evaluator.
Go API
⚠️ CL 1205569 enables CUE_EXPERIMENT=decodeint64 by default, causing cue.Value.Decode to choose int64 rather than int as the default Go type for CUE integer values.
Builtins
CL 1204378 teaches list.UniqueItems to handle incomplete values correctly, fixing a bug in JSON Schema.
CL 1204425 fixes list.MatchN so that it matches final values, like the matchN evaluator built-in, fixing a bug in JSON Schema.
⚠️ CL 1204920 removes the long-deprecated cue.Value.IsClosed method.
⚠️ CL 1205530 removes the long-deprecated cue.Instance.Doc method.
⚠️ CL 1205529 removes the long-deprecated cue/load.Config.BuildTags field.
cmd/go
CL 1204111 fixes some edge cases where CUE comments were lost or duplicated, particularly with cue def.
CL 1204874 re-enables command suggestions when a user makes a typo like cue exprot.
Encodings
JSON Schema spec compatibility is improved further by fixing a number of bugs and adding missing features. Notably, it now supports arbitrary references to internal structure in $ref. JSON Schema's spec test suite has gone from a "pass" rate of 75% to 79% thanks to these efforts.
