 # RustBox changelog
 
+### 0.1.1
+- Fixed the multi-backend compatibility layer compile blockers reported by the Rust compiler: empty `[]` parameter inference no longer overlaps the generic array implementation, legacy SQLite probing imports `rusqlite::OptionalExtension` without colliding with RustBox's own `OptionalExtension`, and MySQL/PostgreSQL transaction batch execution now uses the typed SQLx transaction helpers instead of the lifetime-problematic `raw_sql` executor path.
+- Unified the storage model: `database_backend = sqlite | mysql | pgsql` now selects the database engine for the whole application instead of only the SQL session store; `session_backend = database | redis` either keeps sessions in that same database or moves them to Redis/Redis Sentinel.
+- Added complete SQLite, MySQL and PostgreSQL baselines under `migrations/{sqlite,mysql,pgsql}/schema.sql`. Each schema contains global sessions plus the full account-data schema at baseline version 46; the historical SQLite V001-V046 files are squashed out of the release tree and V047 is reserved for the next schema change across all engines.
+- Preserved per-account data isolation in a shared physical database with deterministic collision-checked table prefixes, while keeping the session table global.
+- Added automatic first-use import of legacy 0.1.0 `data_dir/<user_hash>/db.sqlite` databases at `PRAGMA user_version = 46` into the configured backend. The source database is renamed to `db.sqlite.pre-0.1.1.bak` only after a successful import; older schemas are rejected with an explicit upgrade requirement.
+- Added a backend-neutral database compatibility layer used by the existing Rust data modules and switched application query selection to the SQLite/MySQL/PostgreSQL catalog matching the configured backend.
+- Corrected MySQL/PostgreSQL query dialects and parameter handling, including numbered/reused parameters, upsert syntax, timestamp expressions, JSON address lookup and generated-ID handling.
+- Fixed transaction scope for server databases so cache/message synchronization, header invalidation and other grouped writes execute on the actual MySQL/PostgreSQL transaction connection rather than accidentally falling back to the pool.
+- Removed separate `session.sql` files: sessions are part of each engine's complete `schema.sql`; Redis remains schema-less.
+- Removed stale Python release-contract tests and the unused HTML fixture; retained the runtime JSON fixture used by Rust tests and added native tests for tenant scoping, placeholder adaptation and legacy SQLite import.
+- Made Oxi synchronization treat upstream `backend/migrations/` and `backend/tests/` as RustBox-owned review-only areas so schemas and native tests are never overwritten automatically.
+- Removed the accidental runtime log `qar.txt` from the source tree and refreshed release metadata for 0.1.1.

 ### 0.1.0
 - Cleaned the final release gate for Rust 1.99 Clippy with `-D warnings`: refactored persistent session creation into a typed input struct and fixed all reported collapsible conditionals, redundant closures, needless borrows/question marks, test layout and collection checks without disabling Clippy globally.
 - Fixed fresh user-database provisioning so only SQLite user migrations `V001`-`V046` are applied; session migration `V047` is now exclusively owned by the configured session-store backend and MySQL SQL can no longer be executed against a user SQLite database.
