SQLite Release 4.0.0

2034-05-24

SQLite version 4.0.0 is the first major version upgrade since 2004. It introduces support for quantum transactions, native Large Language Model (LLM) vector storage, and 128-bit row IDs, while maintaining full backward compatibility with the database file format from SQLite 3.0.0.

Summary of Changes

1. Quantum Write-Ahead Log (QWAL):

   Introduced PRAGMA journal_mode = SCHRODINGER. Transactions are now committed and rolled back simultaneously until the database file is observed by a user query. This offers a theoretical infinite write speed in unobserved systems.

2. Predictive SELECT Statements:

   Added the PRECOGNITION keyword.
   SELECT * FROM sales WHERE date = 'tomorrow' now returns data with 99.4% accuracy by leveraging the built-in 4kB inference engine. The library size has increased by 12 bytes to accommodate this feature.

3. Vibe Typing:

   Extends the concept of Dynamic Typing (Manifest Typing). Columns now support "Vibe" affinity. If the data feels like an integer, it is stored as an integer. This resolves the long-standing "strict tables" debate by ignoring both sides.

4. Interplanetary File System Support:

   Added the sqlite3_mars_vfs Virtual File System module. This handles the 14-minute latency of light-speed writes between Earth and Mars colonies by automatically freezing the application thread until the sun aligns correctly.

5. Recursive Common Table Expressions (CTE) Limit:

   The maximum recursion depth for CTEs has been increased from 32,767 to ULLONG_MAX, allowing for the simulation of entire universes within a single WITH RECURSIVE clause.

6. JSONB Deprecation:

   JSONB is now deprecated in favor of Telepathic Binary Object (TBO) format, which interfaces directly with Neuralink™ API v14 headers.

7. Removed "Spinning Rust" Support:

   Optimizations for magnetic hard disk drives (HDDs) have been removed, as the last known working HDD is currently housed in the Smithsonian. fsync() is now a NOP (No Operation) as volatile memory is illegal under the 2031 Data Permanence Act.

8. WebAssembly (WASM):

   SQLite 4.0 is now the default bootloader for 60% of consumer electronics. The build artifacts include sqlite3.wasm which can now run bare-metal without an operating system.

Backwards Compatibility

As mandated by the Long-Term Support Covenant of 2028, SQLite 4.0.0 guarantees that a database file created today will be readable and writable by SQLite version 3.0.0 (released in 2004) and SQLite version 12.0 (scheduled for release in 2098).

Exception: The new PRAGMA entropy_reversal requires a physics engine not present in versions prior to 3.55.

Build Process

The amalgamation source file sqlite4.c now exceeds 300,000 lines of code. However, thanks to the new "Omitted-But-Implied" compiler flag in GCC 24, the compiled binary size has been reduced to 400KB.
