+## v0.5.0 — Many-to-Any support (Issue #60)
+
+### Added
+- **Many-to-Any (M2A) fields are now supported** as display columns. The
+  `related-values` display and per-column overrides resolve the polymorphic
+  `item:collection.field` template syntax, including nested chains such as
+  `{{item:partners_catalog.catalog_id.title}}` (M2A → M2O → scalar). Each
+  junction row renders against its own collection discriminator. Reported by
+  @Abdallah-Awwad in #60.
+- **In-body error state:** when the items request fails, the layout now shows
+  an explicit error notice instead of a blank body under a live pagination bar.
+
+### Fixed
+- **M2A raw template / empty cell:** M2A columns previously rendered the literal
+  display template (or an empty cell) because the query never expanded the
+  per-collection `item:` paths and the renderer never unwrapped the junction
+  rows. Both paths now handle M2A.
+- **M2A column display → 0 results:** adding a column-display template on an M2A
+  field expanded into an invalid junction field path, 403'd the items request,
+  and blanked the table while pagination stayed visible. Invalid/bare tokens are
+  now dropped before the request, and the footer is gated on the same
+  renderable-data condition as the table.
+
+### Refactor
+- New `resolveM2ARelation` helper centralises the M2A junction-shape lookup
+  (discriminator, item field, allowed collections) in one place, mirroring the
+  `resolveTranslationsCollection` pattern — replacing three hand-written copies
+  across the query and render layers.
+- M2A template grammar (`M2A_TOKEN_RE`, `parseM2AToken`, `buildM2AFieldPath`)
+  now lives in `displayHeuristics`, so the field-path emit and the render-side
+  read share a single source and cannot drift.
+- Cell rendering reuses `get` from `@directus/utils` for nested-path access
+  instead of a bespoke walker.

 ### Display Features
 - **Custom Cell Rendering** - Specialized display for different field types
 - **Relationship Support** - Handle M2O, O2M, M2M, M2A relationships with deep data access
-- **Image Preview** - Inline image display with lightbox support and file browser
+- **Image Preview** - Inline image display with an enlarged hover preview and file browser
 - **Tag Support** - Automatic detection and display of tag fields as visual chips with inline popover editor for adding/removing tags
 - **Status Indicators** - Visual representation of boolean and select fields
 - **Translation Support** - Display multiple language translations as separate columns
 - **Column Alignment** - Configurable text alignment per column (left, center, right)
 
 ### Performance
-- **Optimized Loading** - Default 1000 rows with efficient pagination
-- **Smart Caching** - Intelligent data caching for better performance
-- **Lazy Loading** - Load data as needed for large datasets
+- **Native Pagination** - Server-side pagination with selectable page sizes (25, 50, 100, 250, 500, 1000; default 25)
+- **Separate Count Query** - Item count is fetched independently so the table still renders when the count query is restricted by permissions

+3. **Templates** use the `{{ field }}` mustache syntax and may reference related fields
+
+#### Many-to-Any (M2A) templates
+M2A fields are polymorphic — each row points at one of several target collections —
+so their templates use a dedicated `item:` syntax. Tokens are written **relative to
+the field** (do not prefix the field name):
+
+- `{{collection}}` — the name of the row's target collection
+- `{{item:<collection>.<field>}}` — a field on a specific target collection
+- Nested paths are supported, e.g. `{{item:partners_catalog.catalog_id.title}}`
+  (M2A → M2O → value)
+
+Each junction row only resolves the token whose `<collection>` matches its own
+target, so a template can cover every allowed collection at once:
+
+```
+{{collection}}: {{item:partners_catalog.name}} {{item:service.name}}
+```
+
+The editor shows the allowed collections and an example for the selected field. A
+bare token (e.g. `{{name}}`) is intentionally dropped for M2A — use the `item:` form.

 ## API Reference
 
 ### Events
-The extension emits the following events:
+As a Directus layout, the component emits the standard layout sync events:
 
 - `update:selection` - When item selection changes
-- `update:filters` - When filters are modified
-- `update:search` - When search query changes
-- `update:limit` - When page size changes
-- `update:page` - When current page changes
-- `update:sort` - When sort order changes
-- `update:fields` - When visible fields change
+- `update:layoutOptions` - When a layout option changes (column displays, edit mode, alignment, widths, …)
+- `update:layoutQuery` - When the query changes (fields, sort, page, limit)
+- `update:search` - When the search query changes
+
+The `filter` prop is consumed read-only (filtering is driven by Directus), so no
+`update:filter` event is emitted.
 
 ### Composables
 Available composables for extension development:
 
-- `useApi()` - API operations wrapper
+- `useTableApi()` - API operations wrapper (fetch, count, update, delete, export)
 - `useAliasFields()` - Field aliasing for complex queries
-- `useLanguageSelector()` - Translation language management
+- `useColumnDisplays()` - Per-column display-template overrides

 ### Inline editing not working

-- Ensure fields are not read-only
-- Verify field types are supported
+- Make sure "Edit Mode" is enabled in the Layout Options sidebar
+- Check field permissions in Directus (no update permission = read-only)
+- Ensure fields are not configured as read-only
+- Note: relational fields (M2O, O2M, M2M, M2A) are display-only by design
 
 ### Performance issues
-- Reduce default row count
-- Enable pagination for large datasets
-- Check browser console for errors
+- Choose a smaller page size (the per-page selector defaults to 25)
+- Check the browser console for errors
