Release 6.0.1

[YogeshPraj]

Promotes the 6.0.1-preview.* line to a stable 6.0.1 release. No code changes beyond preview.3 — this is a version bump + CHANGELOG tidy.

Changes

• src/RulesEngine/RulesEngine.csproj: <Version> 6.0.1-preview.3 → 6.0.1
• CHANGELOG.md:
  • New [6.0.1] rollup section summarising the delta since 6.0.0.
  • Backfilled the missing preview.3 entries for Fix warmup regression: avoid per-expression AppDomain assembly scan (fixes #739) #740 (warmup fix) and Validate duplicate param names and input/global collisions with clear errors #743 (duplicate param-name validation) — both merged after preview.2 was cut but weren't reflected in CHANGELOG at the time.

Headline changes in 6.0.1 (since 6.0.0)

Performance

• Restored compiled-expression cache in RuleExpressionParser — 100×–1900× speedups on paths not served by RulesCache (Huge Performance Degredation in version 5.0.1 #673, Restore compiled-expression cache in RuleExpressionParser (fixes #673) #727).
• Fixed warmup regression from per-expression AppDomain assembly scans in CustomTypeProvider — ~6.6× faster registration on realistic large workflows (Warmup still ~6x slower than 5.0.3: per-expression AppDomain assembly scan in CustomTypeProvider (root cause of #707) #739, Fix warmup regression: avoid per-expression AppDomain assembly scan (fixes #739) #740).

Features

• Opt-in ReSettings.EnableParallelRuleCompilation for further warmup gains on very large (10k+ rule) workflows (Add opt-in parallel rule compilation for faster workflow warmup #741, Add opt-in parallel rule compilation (improved on top of #741) #744).
• IRulesEngine.ExecuteAllRulesAsync overload accepting a CancellationToken (ExecuteAllRulesAsync should support a CancellationToken as argument #609).
• ReSettings.AutoExecuteActions (default true) — set to false to evaluate rules without automatically running actions (Possibility to choose the execution of all actions or not #596).

Fixes

• Cleaner errors for exception propagation (EnableExceptionAsErrorMessage = false does not actually throw exception, but ignores/supresses it #624), list schema union (Rule Parameter is inferring first element type to later elements in expandoObject list #704), OutputExpression syntax hints (OutputExpressionAction always throws “Expression is missing an 'as' clause” when returning an object #711), global-param dedup (Global parameters will be executed multiple times #714), object-return diagnostics (Dynamic LINQ execution fails silently or throws parsing error when method returns object #717), ExecuteActionWorkflowAsync error message population (ExceptionMessage not populated in ExecuteActionWorkflowAsync #519), ActionContext null guard (Using OnSuccess/OnFailure Actions within a rule causes a NullReferenceException when the Context is not defined #576), deep dotted ErrorMessage interpolation (The interpolation expression for the sub-expression "ErrorMessage" is not functioning. #696), STJ JsonElement unwrap (System.Text.Json migration not working as expected #668), and duplicate/collision param-name validation (Validate duplicate param names and input/global collisions with clear errors #743).

Test plan

• All 178 unit tests pass on net6.0 / net8.0 / net9.0 / net10.0.
• No code changes — only version + docs.
• <PackageReleaseNotes> still points at CHANGELOG.md, which now has the rollup.
