v1.4.2

• Improved Options-page reliability by consolidating browser API compatibility handling for tab actions and diagnostics messaging.
• Improved diagnostics UX on failure by clearing stale summary/list content so outdated results are not shown.
• Simplified recovery list rendering flow to reduce UI edge-case drift while preserving existing reopen behavior.
• Refactored Options runtime internals into focused modules for easier maintenance without changing suspend policy semantics.

v1.4.1

• Reduced background CPU overhead by precompiling host/profile matching and removing redundant suspend-path URL parsing.
• Added bounded adaptive sweep backoff (+0..+5 minutes) under heavy workloads to reduce runtime churn on large tab sets.
• Reduced suspended tab memory footprint by simplifying the generated self-contained data: suspended page payload.
• Simplified suspended page presentation by removing the extra Original URL heading line and the Ready to restore this tab. status line.
• Expanded regression coverage for compiled matcher parity, adaptive sweep backoff behavior, and suspended payload size constraints.

v1.4.0

• Added a new Why tabs are not suspending diagnostics panel in Options with manual refresh.
• Added local-only per-tab suspension diagnostics showing tab title, full URL, and deterministic suspend reason.
• Added reason summary counts across open tabs, including eligible tabs for transparency.
• Added bounded diagnostics rendering (max 200 tab rows) to keep Options responsive on large tab sets.
• Added runtime diagnostics endpoint and regression coverage for diagnostics success, failure, empty, and truncated states.

v1.3.0

• Added local configuration export to JSON from Options for portable backups.
• Added staged configuration import flow with explicit preview, apply, and cancel controls.
• Added versioned portable schema (exportSchemaVersion: 1) with strict malformed/unsupported payload rejection.
• Added atomic import apply path that writes settings and recovery state together in one storage transaction.
• Expanded regression coverage for portable parser/serializer behavior and end-to-end options import/export UX.

v1.2.0

• Added per-site policy profiles so specific domains can override global suspend behavior.
• Added deterministic profile match precedence: exact host before wildcard, then longer host target, then earliest row.
• Added profile override controls in Settings for idle timeout, pinned/audible skip behavior, and per-site exclude-from-suspend.
• Upgraded settings storage to schema v2 with decode-time migration from existing schema v1 data.
• Expanded regression coverage for profile matching, schema migration/sanitization, options profile CRUD, and suspend runtime integration.

v1.1.8

• Hardened background listener payload handling with shared typed guards to reduce event-contract drift risk without changing suspend behavior.
• Centralized Options page status and validation copy into typed message maps while preserving exact user-visible text.
• Added dedicated settings/activity store invariant test suites for decode/sanitize boundary, dedupe, and cap behaviors.
• Expanded recovery-store test coverage for trim/cap invariants and kept storage schema compatibility unchanged.

v1.1.7

• Improved background runtime consistency by centralizing runtime state ownership, reducing edge-case drift during event-heavy tab/window activity.
• Simplified tab query/update compatibility handling with focused wrappers, preserving existing behavior while reducing maintenance risk.
• Kept suspend, restore, settings, and recovery flows behavior-compatible with no required user migration or settings reset.
• Expanded regression verification across background wiring, settings runtime, suspend action, and full suite coverage to confirm no behavior regressions.

v.1.1.6

• Split Options page feedback into separate settings and recovery status channels so save/load messages do not overwrite reopen results.
• Added a dedicated recovery action live-status region for clearer reopen success/failure feedback.
• Centralized suspended-page restore/copy/unavailable text into grouped message maps with explicit invalid-URL reason mapping.
• Added regression coverage for status-channel isolation on recovery success and failure flows.

v1.1.4

• Reduced suspend-path CPU overhead by consolidating URL validation/parsing into a single metadata-aware evaluation step.
• Optimized background activity persistence to avoid unnecessary pre-write sorting/allocation while preserving deterministic stored ordering.
• Improved Options recovery list responsiveness by reusing unchanged rows during rerenders instead of rebuilding the full list.
• Preserved existing suspend safety guards, action-click behavior, and storage schema compatibility with full regression coverage.

v1.1.3

• Removed legacy background PING message handling to reduce unsupported runtime API surface.
• Consolidated storage callback/promise compatibility handling into a shared adapter used by settings, activity, and recovery stores.
• Reduced background test-hook surface (__testing) to only active regression needs.
• Kept suspend, settings, and recovery behavior stable with full regression pass.
