• Migrate the checker.Coster to the ast.Expr [#​798]

Fixes

• Nil safety checks for cel.Ast [#​784]
• Fix cost estimates to propagate result sizes [#​787]

Minor release to address documentation gaps and additional methods to make unknowns more useful

Fixes

• Helpers for accessing unknown state information [#​781]

Full Changelog: google/cel-go@v0.17.0...v0.17.1

v0.17.0

Compare Source

At a high-level this release introduces several changes which should improve ease of use
while also improving the evaluation safety and quality:

• Standard library functions may be extended by using cel.Function options.
• The unknown type now contains information about which field references were unknown.
• Type representations have been consolidated to *types.Type.
• New options have been added to add custom AST validations which are run after type-checking.
• Additional macros were added for optional types, and a new extension was added for list slicing.
• The cel.ContextProtoVars method has been added to bind proto fields to variable names,
  complementing cel.DeclareContextProto.

Features

• Unify decls.Type with types.Type [#​745]
• Introduce optFlatMap and OptionalTypes documentation [#​744]
• Include expression id on parser and checker errors [#​725]
• Implement errors.Unwrap for types.Err. [#​728]
• Allow extension of stdlib functions [#​747]
• Add list library with slice method [#​753]
• Export FormatCELType in the 'cel' package [#​763]
• Validators for common literals and use cases [#​765]
• Comprehension nesting limit validator [#​769]
• Unify type adapter / provider representations [#​770]
• Benchmark harness with some initial reference cases [#​750]
• Simplified partial state evaluation [#​766]
• Update types.Unknown with attribute trails [#​776]
• ContextProtoVars() to simplify proto-based inputs [#​779]
• Variadic logical operator AST support [#​726]

Fixes

• Add the overload reference for optional field selection [#​730]
• Correct a typo in the README [#​731]
• Clear iteration variable data during expression pruning [#​740]
• Restore iter range pruning on comprehension ASTs [#​757]

Breaking Changes

The following API changes may break users of cel-go:

• Removal of *types.TypeValue, replaced by *types.Type
• Removal of *exprpb.Type from public interfaces such as the checker.AstNode
• Change in type definition for *types.Unknown. Switch from a type alias for []int64 to a structured type.
