+# Audita v2.0.0
+
+Audita v2 adopts ConfigKit for configuration and PromptKit for LLM execution,
+adds resilient processing and focused reports, and improves correction prompts
+and validation. This is an intentional breaking release; existing installations
+must migrate their configuration and invocation settings.
+
+- Configuration uses `version: 2` YAML, named backends, PromptKit model profiles,
+  and optional named overlays. Offline configuration validation and inspection
+  expose effective settings, selected profiles, and provenance.
+- Proposal and validation calls share per-backend capacity. PromptKit handles
+  transport retries and structural response repair within bounded operation
+  timeouts.
+- Transcript chunks remain fixed through the LLM stages. Recoverable model
+  failures preserve progress and allow other work to continue. If every LLM
+  operation fails recoverably, processing still produces the deterministically
+  normalized transcript without LLM corrections. Cancellation, application
+  failures, and required output failures remain fatal.
+- Ordinary output includes `errors.yml`, `recoveries.yml`, and `report.md`, plus
+  a brief completion summary. Detailed correction and LLM diagnostics are opt-in
+  with `--debug`; `--reporting=false` suppresses all three ordinary reports.
+- Empty replacement text supports validated span deletion while preserving a
+  nonblank segment. Validator responses retain usable decisions despite missing,
+  duplicate, or extraneous entries; unavailable decisions never approve an edit.
+- Prompts use short request-local references, consistent shared instructions,
+  and relevant neighboring/glossary context for validation. Spoken-word cleanup
+  can reduce accidental protected-name repetition subject to validation.
+
+Follow the [v2 migration guide](../migrations/v2.md) before upgrading. Version-1
+configuration, implicit environment-setting overlays, retired model/credential/
+concurrency flags, and the former JSON report interface have no compatibility
+shim. Start from the maintained examples linked in that guide, configure profiles
+and credential references, and validate the new configuration. Update report and
+debug consumers for the [current output contract](../integrations/output-files.md).
+
+Linux amd64 and arm64 remain the production targets; macOS arm64 is best effort
+for development. Binary and checksum delivery runs asynchronously after source/tag
+publication, as described in the [release procedure](../release.md).
