### String-based configuration

Settings that took `SMW_*` constants now accept plain strings; bitmask settings take arrays of strings. The constant form still works in 7.x with a deprecation notice and is removed in 8.0.

| Setting | Legacy form (deprecated) | New default | Accepted values |
|---|---|---|---|
| `$smwgShowFactbox` | `SMW_FACTBOX_NONEMPTY` | `'nonempty'` | `'hidden'`, `'special'`, `'nonempty'`, `'shown'` |
| `$smwgShowFactboxEdit` | `SMW_FACTBOX_NONEMPTY` | `'nonempty'` | `'hidden'`, `'special'`, `'nonempty'`, `'shown'` |
| `$smwgFactboxFeatures` | `SMW_FACTBOX_CACHE \| ...` | `[ 'cache', 'purge-refresh', 'display-subobject', 'display-attachment' ]` | `'cache'`, `'purge-refresh'`, `'display-subobject'`, `'display-attachment'` |
| `$smwgQEqualitySupport` | `SMW_EQ_SOME` | `'some'` | `'none'`, `'some'`, `'full'` |
| `$smwgQConceptCaching` | `CONCEPT_CACHE_HARD` | `'hard'` | `'none'`, `'hard'`, `'all'` |
| `$smwgSparqlRepositoryFeatures` | `SMW_SPARQL_NONE` | `'none'` | `'none'`, `'connection-ping'` |
| `$smwgResultFormatsFeatures` | `SMW_RF_TEMPLATE_OUTSEP` | `'template-outsep'` | `'none'`, `'template-outsep'` |
| `$smwgQFeatures` | `SMW_PROPERTY_QUERY \| SMW_CATEGORY_QUERY \| ...` | `[ 'property', 'category', 'concept', 'namespace', 'conjunction', 'disjunction' ]` | `'property'`, `'category'`, `'concept'`, `'namespace'`, `'conjunction'`, `'disjunction'` |
| `$smwgQConceptFeatures` | `SMW_PROPERTY_QUERY \| SMW_CATEGORY_QUERY \| ...` | `[ 'property', 'category', 'concept', 'namespace', 'conjunction', 'disjunction' ]` | `'property'`, `'category'`, `'concept'`, `'namespace'`, `'conjunction'`, `'disjunction'` |
| `$smwgQSortFeatures` | `SMW_QSORT \| SMW_QSORT_RANDOM` | `[ 'sort', 'random' ]` | `'sort'`, `'random'`, `'unconditional'` |
| `$smwgSparqlQFeatures` | `SMW_SPARQL_QF_REDI \| SMW_SPARQL_QF_SUBP \| SMW_SPARQL_QF_SUBC` | `[ 'redirects', 'subproperties', 'subcategories' ]` | `'redirects'`, `'subproperties'`, `'subcategories'`, `'collation'`, `'no-case'` |
| `$smwgCategoryFeatures` | `SMW_CAT_REDIRECT \| SMW_CAT_INSTANCE \| SMW_CAT_HIERARCHY` | `[ 'redirect', 'instance', 'hierarchy' ]` | `'redirect'`, `'instance'`, `'hierarchy'` |
| `$smwgBrowseFeatures` | `SMW_BROWSE_TLINK \| ...` | `[ 'toolbox-link', 'show-incoming', 'show-group', 'use-api' ]` | `'toolbox-link'`, `'show-inverse'`, `'show-incoming'`, `'show-group'`, `'show-sortkey'`, `'use-api'` |
| `$smwgAdminFeatures` | `SMW_ADM_REFRESH \| ...` | `[ 'refresh', 'setup', 'disposal', 'pstats', 'fullt', 'maintenance-script-docs', 'show-overview', 'alert-last-optimization-run' ]` | `'refresh'`, `'disposal'`, `'setup'`, `'pstats'`, `'fullt'`, `'maintenance-script-docs'`, `'show-overview'`, `'alert-last-optimization-run'` |
| `$smwgParserFeatures` | `SMW_PARSER_STRICT \| SMW_PARSER_INL_ERROR \| SMW_PARSER_HID_CATS` | `[ 'strict', 'inline-errors', 'hidden-categories' ]` | `'strict'`, `'unstrip'`, `'inline-errors'`, `'hidden-categories'`, `'links-in-values'` |
| `$smwgDVFeatures` | `SMW_DV_PROV_REDI \| SMW_DV_MLTV_LCODE \| ...` | `[ 'provider-redirect', 'monolingual-langcode', 'pattern-validation', 'wpv-display-title', 'time-calendar-model', 'preferred-label', 'provider-link-hint' ]` | `'provider-redirect'`, `'monolingual-langcode'`, `'number-value-usespaces'`, `'pattern-validation'`, `'wpv-display-title'`, `'provider-display-title'`, `'unique-constraint'`, `'time-calendar-model'`, `'preferred-label'`, `'provider-link-hint'`, `'wpv-pipetrick'` |
| `$smwgFulltextSearchIndexableDataTypes` | `SMW_FT_BLOB \| SMW_FT_URI` | `[ 'blob', 'uri' ]` | `'blob'`, `'uri'`, `'wikipage'` |
| `$smwgRemoteReqFeatures` | `SMW_REMOTE_REQ_SEND_RESPONSE \| SMW_REMOTE_REQ_SHOW_NOTE` | `[ 'send-response', 'show-note' ]` | `'send-response'`, `'show-note'` |
| `$smwgExperimentalFeatures` | `SMW_QUERYRESULT_PREFETCH \| SMW_SHOWPARSER_USE_CURTAILMENT` | `[ 'queryresult-prefetch', 'showparser-curtailment' ]` | `'queryresult-prefetch'`, `'showparser-curtailment'` |
| `$smwgFieldTypeFeatures` | `false` or `SMW_FIELDT_CHAR_NOCASE \| SMW_FIELDT_CHAR_LONG` | `false` | `false` (component disabled), or any subset of `'char-nocase'`, `'char-long'` |
| `$smwgQueryProfiler` | `true` (basic) or `SMW_QPRFL_DUR \| SMW_QPRFL_PARAMS` | `[]` | `false` (profiling disabled), `[]` (basic, no detail fields), or any subset of `'parameters'`, `'duration'` |
| `$smwgSpecialAskFormSubmitMethod` | `SMW_SASK_SUBMIT_POST` | `'post'` | `'get'`, `'get.redirect'`, `'post'` |
| `$smwgCheckForConstraintErrors` | `SMW_CONSTRAINT_ERR_CHECK_ALL` | `'check/all'` | `false`, `'check/main'`, `'check/all'` |

Unknown strings are ignored with a structured-log warning. The last two settings (`$smwgSpecialAskFormSubmitMethod`, `$smwgCheckForConstraintErrors`) need no normalizer entry because their `SMW_SASK_SUBMIT_*` / `SMW_CONSTRAINT_ERR_CHECK_*` constants already resolve to the listed string values; the constants continue to work.

`$smwgQueryProfiler`'s `extension.json` default changes from `true` to `[]`; behaviour is unchanged because both forms produce zero flag bits in `Options::isFlagSet`. Note that `[]` enables basic profiling (no detail fields), it does NOT disable; use `false` to disable profiling entirely. The legacy `true` form is also accepted with a deprecation notice and will be removed in 8.0.

### Removed legacy settings

The runtime shim that rewrote settings deprecated in SMW 3.1 and 3.2 to their replacements is gone. Update any of these names in `LocalSettings.php` to the replacement below; otherwise the legacy names are silently ignored. Special:Admin no longer surfaces them as deprecation notices.

### Renamed `<section>` parser tag

SMW's `<section>` parser tag is renamed to `<smwsection>` so it no longer collides with the `<section>` tag registered by extensions such as [LabeledSectionTransclusion](https://www.mediawiki.org/wiki/Extension:Labeled_Section_Transclusion). The rendered output is unchanged (still an HTML `<section class="smw-property-specification">` element), so styling and property-page tabs are unaffected; only the wikitext tag name changes.

Saved pages are not migrated automatically. Update any page (typically in the `Property:` namespace) that wraps content in `<section>...</section>` for SMW, replacing the tags with `<smwsection>...</smwsection>`. The `$smwgSupportSectionTag` setting still controls whether SMW registers its tag; with the collision resolved, most wikis no longer need to disable it.

## Developers

### Query API module subclasses now require a `QuerySourceFactory`

`SMW\MediaWiki\Api\Query`, the base class for SMW's query API modules, gained a
required third constructor argument:

```php
public function __construct(
	ApiMain $main,
	string $action,
	QuerySourceFactory $querySourceFactory
)
```

SMW's own `ask` and `askargs` modules are registered so MediaWiki's ObjectFactory
injects the dependency. Extensions that register an API module subclassing
`Api\Query` must do the same — add the `SMW.QuerySourceFactory` service to the
module's `extension.json` registration:

```json
"APIModules": {
	"yourmodule": {
		"class": "Your\\Api\\Module",
		"services": [
			"SMW.QuerySourceFactory"
		]
	}
}
```

A subclass still registered by bare class name — or instantiated with only
`$main` and `$action` — fails with an `ArgumentCountError`.

### Removed job aliases

All job types must now use their `smw.*` names. The following aliases no longer work:

### Removed internal APIs

* `ServicesFactory::getMediaWikiLogger()` and the `SMW\Utils\Logger` wrapper — use `MediaWiki\Logger\LoggerFactory::getInstance( $channel )` directly
* **Cache services moved to MediaWiki primitives** (the bundled `onoi/cache` and `onoi/blob-store` dependencies are gone):
  * `ServicesFactory::getCache()` and the `SMW.Cache` service are removed — use `ServicesFactory::getObjectCache()` (or the `SMW.ObjectCache` service), which returns a `Wikimedia\ObjectCache\BagOStuff` over `$smwgMainCacheType`.
  * `CacheFactory::newFixedInMemoryCache()`, `newNullCache()`, `newMediaWikiCache()`, `newMediaWikiCompositeCache()`, and `newCacheByType()` are removed — use MediaWiki's `Wikimedia\ObjectCache\BagOStuff` / `MapCacheLRU`, or the in-tree `SMW\Cache\InMemoryLruCache`, directly.
  * `ServicesFactory::newBlobStore()` and `CacheFactory::newBlobStore()` are renamed to `newQueryResultStore()`, and the `'BlobStore'` service route is now `'QueryResultStore'` (they construct a `SMW\Query\Cache\QueryResultStore`).
  * `CacheFactory::getPurgeCacheKey()` is removed — build the key with `smwfCacheKey( SMW\MediaWiki\Hooks\ArticlePurge::CACHE_NAMESPACE, $articleId )`.
  * `SMW\InMemoryPoolCache::__construct()` no longer takes a `CacheFactory` argument — resolve the pool via `InMemoryPoolCache::getInstance()`.
