FiQueLa version 2.12.0 is now available!

Added

FROM aliasing: FROM source AS alias in FQL and ->from('source')->as('alias') in fluent API. Aliased fields accessible via alias.field dot notation.
Fluent JOIN aliasing: ->join($query)->as('alias')->on(...) as alternative to passing alias as parameter. Backward-compatible — ->join($query, 'alias') still works.
Aliased wildcard alias.*: select all fields from an aliased source (FROM or JOIN) using alias.* in SELECT. Throws SelectException on ambiguous field conflicts.
Wildcard * support in EnhancedNestedArrayAccessor: path traversal now supports * token to expand all keys of an associative array.
Context-aware as() method: as() in Query now detects context — aliases SELECT field, FROM source, or JOIN depending on what was called before it.
LastClause enum (FQL\Enum\LastClause) for internal context tracking.
Subquery JOIN support in FQL parser: LEFT JOIN (SELECT ... FROM ... WHERE ...) AS alias ON .... Parser recursively handles nested SELECT statements in JOIN clauses.
Query::isSimpleQuery() method to detect queries without any clauses (SELECT * FROM source only).
Query::provideFileQuery(bool $withQuery = false) parameter to include FROM path in the returned FileQuery.

Commas are now mandatory between expressions in SELECT, GROUP BY, and ORDER BY clauses in FQL strings. SELECT id, name, price is valid; SELECT id name price throws UnexpectedValueException. Fluent API (->select('id, name')) is unaffected.

as() moved from Select trait to Query class as a unified context-aware method. Internally delegates to asSelect(), asFrom(), or asJoin().
JOIN methods (join, innerJoin, leftJoin, rightJoin, fullJoin) now accept alias as optional parameter (string $alias = ''). Alias is still required but can be set via ->as() fluently.
JOIN __toString() renders simple joins as direct source references instead of subqueries.
EnhancedNestedArrayAccessor::parsePath() token type extended with wildcard flag.
JOIN ON conditions now resolve dot-notation keys via accessNestedValue(), supporting aliased field paths (e.g. ON u.id = c.id).
SqlLexer tokenizer now respects parenthesis depth — control keywords inside (...) are not treated as block delimiters.
SqlLexer::defaultTokenize() now emits commas as separate tokens instead of stripping them.

FQL parser: LIMIT before UNION no longer consumes the UNION token as offset.
FQL parser: FROM ... AS alias tokenization and parsing support in SqlLexer.
