+## [1.4.4] – 2026-04-20
+
+### Updated
+- **README.md restructuring** — consolidated `get_activities` and `like_post` into Wall & Activities section
+  - `get_activities` moved from Lists & Tasks to Wall & Activities (belongs with wall functionality)
+  - `like_post` reference removed from Lists & Tasks (consolidated in one section)
+  - Version bump in README header: v1.3.1 → v1.4.3
+
+### Notes
+- Documentation-only release; no code changes
+- All tools remain functional and unchanged
+- Improves UX by grouping related wall/activity tools in one section
+
+## [1.4.3] – 2026-04-18
+
+### Improved
+- **Usability: ID resolution in docstrings** — enforce transparent display of human-readable names:
+  - `get_tasks`: Document required member/category name resolution before user display
+  - `get_lists`: Document required circle name resolution before user display
+  - `get_activities`: Document required author name resolution before user display
+  - `get_wall_posts`: Document required author name resolution before user display
+  - `get_members`: Added proactive call guidance before presenting member-ID data
+  - `get_circles`: Added proactive call guidance before presenting circle-ID data
+  - `get_categories`: Added proactive call guidance for shopping list tasks
+  - `get_meal_plan`: Document required recipe name resolution for recipe_id before user display
+  - `CLAUDE.md`: Added general usability rule at top of implementation section
+
+### Notes
+- No breaking changes; docstring enhancements only
+- All tools remain backward compatible
+- Ensures consistent UX: no raw numeric/metaIDs shown to users in any context
+
+## [1.4.2] – 2026-04-18
+
+### Fixed
+- **`get_tasks` support for secondary circles** — lists in non-primary circles now return tasks correctly
+  - Circle is automatically derived from `list_id` format (`taskList/<circleNum>_<listNum>`)
+  - Scope parameter passed to `accgetallfamily` call; matches `get_lists` pattern
+  - Docstring updated to clarify circle support and list_id format requirement
+
+### Notes
+- `_accgetallfamily()` now accepts optional `scope` parameter for secondary circle support
+- No breaking changes; all existing code remains compatible
+
+## [1.4.1] – 2026-04-17
+
+### Improved
+- **Docstring enhancements** — clearer tool usage guidance for new Claude sessions:
+  - `get_wall_posts`: Added note that results include automatic activity entries (task updates, list changes)
+  - `get_activities`: Expanded description and added distinction from `get_wall_posts`
+  - `like_post`: Extended post_id examples to include `task/` and `taskList/` IDs from activities
+  - `get_recipe_categories`: Added usage notes (IDs for create/update, 5 free-tier categories, family-wide scope)
+  - `add_meal_note`: Clarified create-only behavior; to update, delete then recreate
+  - `clear_list`: Moved risk warning (default deletes all tasks) to opening line for visibility
+  - `create_recipe`: Verified IMPORTANT confirmation line present
+
+### Notes
+- No breaking changes; docstring improvements only
+- All tools remain backward compatible
+
+## [1.4.0] – 2026-04-17
+
+### Added
+- **Unit test suite** (`tests/test_unit.py`) — comprehensive tests for core modules
+  - `fw_client.py`: Error handling (top-level `ex`/`un`, nested `a00.un.un`/`a00.ex.ex`, successful responses)
+  - `recipes.py`: `ingredients_parsed` parser (newline handling, empty lines, headings, commas)
+  - `lists.py`: System list name translation (SYS-CAT-SHOPPINGLIST, SYS-CAT-TODOS, unknown names)
+  - `server.py`: `_validate_date()` (ISO YYYY-MM-DD validation, format errors)
+  - `server.py`: `_err()` helper (JSON response format, Unicode, special characters)
+- All tests use `unittest.mock` (stdlib, no external dependencies)
+- Tests run without API access; all HTTP calls are mocked
+- Framework: pytest with asyncio support
+
+### Notes
+- Run tests: `uv run pytest tests/test_unit.py -v`
+- No breaking changes; release is testing infrastructure only
+
+## [1.3.1] – 2026-04-17
+
+### Fixed
+- **`add_comment` response parser**: corrected response structure from `a00.r.r` with `metaId`
+  to nested `a00.r.r.comment.commentId`; response now includes `"created": true` flag
+- **`add_comment` error handling**: now returns error messages directly instead of warnings
+
+### Added
+- **`delete_wall_post`** — permanently delete a wall post using the `metadelete` endpoint
+  (identical to deleting tasks and recipes)
+
+### Notes
+- All wall post tools now complete CRUD operations (Create, Read, Update via like_post, Delete)
+- Test post (wall/16282169_31146617) removed from production after verification
+
+## [1.3.0] – 2026-04-17
+
+### Added
+- **Wall post reading**: `get_wall_posts` — retrieve recent wall posts with author, text,
+  creation date, like count, liked-by-me flag, and comment count
+- **Wall post writing**: `create_wall_post` — publish a new status post to the wall
+- **Comments**: `add_comment` — add a comment to a wall post or activity
+- All three new wall post tools require user confirmation before calling
+
+### Notes
+- `get_wall_posts` supersedes the activity-listing functionality of `get_activities`
+  (which continues to exist for backward compatibility)
+- `like_post` already supports both wall posts and activities; verified to work
+  with metaIds from both `get_wall_posts` and `get_activities`
+- Post IDs are in the format `wall/<familyid>_<postid>`
+
+## [1.2.0] – 2026-04-17
+
+### Added
+- **Unlike support** for `like_post`: passing `like=False` now removes a STAR reaction via
+  `add=$empty, remove.0=STAR` (array dot-notation). New optional `mood` parameter (default `"STAR"`).
+- **Reminder write support** for `create_task` and `update_task`:
+  - `reminder_unit`: `"MINUTE"`, `"HOUR"`, or `"DAY"`
+  - `reminder_value`: non-negative integer (e.g. `30` for "30 minutes before")
+  - `clear_reminder` (update_task only): remove reminder
+- The correct wire format uses **dot-notation** subfields
+  (`reminder.reminderUnit`, `reminder.reminderValue`, `reminder.reminderType`,
+  `reminder.localId`) — flat top-level keys, JSON-string, and bracket-notation
+  are silently ignored by the server.
+
+### Fixed
+- `update_task` docstring: removed the "reminders not supported" warning — the
+  v1.1.2 write format was flat, which the FiZ encoder silently drops; the
+  dot-notation variant works on both Free and Premium accounts.
+
+### Investigation notes (2026-04-17)
+- Verified via isolated fuzz test (fresh test task per variant): only dot-notation
+  succeeds; every other encoding is accepted with HTTP 200 and `lastAction: UPDATED`
+  but the reminder remains at default `{reminderType: NONE, reminderValue: 0}`.
+- `reminder.localId` is optional.
+- Partial block updates (e.g. only `reminder.reminderType=NONE`) return
+  `task reminder invalid` — the full inactive block must be sent to clear.
+- Valid `reminderUnit` values: `MINUTE`, `HOUR`, `DAY`. `WEEK` is rejected by the
+  API enum decoder.
+- Reminder + recurrency can be set in a single `taskupdate2` call without interference.
+
+## [1.1.2] – 2026-04-17
+
+### Fixed
+- `update_task`: removed non-functional reminder write parameters (`reminder_unit`,
+  `reminder_value`, `clear_reminder`) — exhaustive FW_DEBUG testing (flat params,
+  JSON-string, PHP-bracket, all string values, with/without `localId`, alternative
+  endpoints) on both Free and Premium accounts confirmed that `taskupdate2` silently
+  ignores all reminder fields; historical SNOOZE reminders were set via the mobile
+  app's Service Worker which transforms requests in ways not reproducible via direct API
+- `update_task`: docstring now explicitly states reminders are read-only
+- SPEC.md: documented reminder write limitation with investigation findings
+- CLAUDE.md: updated reminder row to reflect read-only status
+
+### Investigation notes
+- Tested formats: flat int params, flat string params, JSON-encoded string value,
+  PHP-bracket notation (`reminder[reminderUnit]=DAY`), no-`localId` variant
+- Tested endpoints: `tasksetalert`, `taskalertput`, `taskreminderset`, `taskalert`,
+  `tasknotification` — all return `"The call X is not registered"`
+- Verified on both test account (Free) and real account (Premium) — same result
+- Recurrency write via flat params is confirmed working (separate from reminder)
+
+---
+
+## [1.1.1] – 2026-04-17
+
+### Fixed
+- `update_task`: recurrency and reminder fields now sent as flat top-level parameters
+  instead of nested objects — the FiZ `Ai()` encoder does not support nested objects;
+  `recurrencyDescriptor`/`reminder` keys are never sent, fields go directly to top level
+  (e.g. `recurrency=WEEKLY`, `reminderUnit=DAY` rather than `recurrencyDescriptor={...}`)
+- SPEC.md and CLAUDE.md corrected to document the flat encoding
+
+---
+
+## [1.1.0] – 2026-04-17
+
+### Added
+- `update_task`: recurrency parameters (`recurrency`, `recurrency_interval`, `rrule`,
+  `clear_recurrency`) — set or remove task recurrence rules via `recurrencyDescriptor`
+- `update_task`: reminder parameters (`reminder_unit`, `reminder_value`, `clear_reminder`)
+  — set or remove task reminders via `reminder`
+- SPEC.md: documented `recurrencyDescriptor` and `reminder` fields for `taskupdate2`
+  (verified via JS-Bundle xb-Encoder / fc-Encoder)
