Changelog

• 2026-04-04 v1.48.2:

  • Fix ABI mapping mismatch in the pre-update hook trampoline that caused silent truncation of large 64-bit RowIDs.
  • Ensure the Go trampoline signature correctly aligns with the public sqlite3_preupdate_hook C API, preventing data corruption for high-entropy keys (e.g., Snowflake IDs).
  • See [GitLab merge request #98](https://gitlab.com/cznic/sqlite/-/merge_requests/98), thanks Josh Bleecher Snyder!
  • Fix the memory allocator used in (*conn).Deserialize.
  • Replace tls.Alloc with sqlite3_malloc64 to prevent internal allocator corruption. This ensures the buffer is safely owned by SQLite, which may resize or free it due to the SQLITE_DESERIALIZE_RESIZEABLE and SQLITE_DESERIALIZE_FREEONCLOSE flags.
  • Prevent a memory leak by properly freeing the allocated buffer if fetching the main database name fails before handing ownership to SQLite.
  • See [GitLab merge request #100](https://gitlab.com/cznic/sqlite/-/merge_requests/100), thanks Josh Bleecher Snyder!

• 2026-04-03 v1.48.1:

  • Fix memory leaks and double-free vulnerabilities in the multi-statement query execution path.
  • Ensure bind-parameter allocations are reliably freed via strict ownership transfer if an error occurs mid-loop or if multiple statements bind parameters.
  • Fix a resource leak where a subsequent statement's error could orphan a previously generated rows object without closing it, leaking the prepared statement handle.
  • See [GitLab merge request #96](https://gitlab.com/cznic/sqlite/-/merge_requests/96), thanks Josh Bleecher Snyder!

• 2026-03-27 v1.48.0:

  • Add _timezone DSN query parameter to apply IANA timezones (e.g., "America/New_York") to both reads and writes.
  • Writes will convert time.Time values to the target timezone before formatting as a string.
  • Reads will interpret timezone-less strings as being in the target timezone.
  • Does not impact _inttotime integer values, which will always safely evaluate as UTC.
  • Add support for _time_format=datetime URI parameter to format time.Time values identically to SQLite's native datetime() function and CURRENT_TIMESTAMP (YYYY-MM-DD HH:MM:SS).
  • See [GitLab merge request #94](https://gitlab.com/cznic/sqlite/-/merge_requests/94) and [GitLab merge request #95](https://gitlab.com/cznic/sqlite/-/merge_requests/95), thanks Josh Bleecher Snyder!

• 2026-03-17 v1.47.0: Add CGO-free version of the vector extensions from https://github.com/asg017/sqlite-vec. See vec_test.go for example usage. From the GitHub project page:

  • Important: sqlite-vec is a pre-v1, so expect breaking changes!
  • Store and query float, int8, and binary vectors in vec0 virtual tables
  • Written in pure C, no dependencies, runs anywhere SQLite runs (Linux/MacOS/Windows, in the browser with WASM, Raspberry Pis, etc.)
  • Store non-vector data in metadata, auxiliary, or partition key columns
  • See [GitLab merge request #93](https://gitlab.com/cznic/sqlite/-/merge_requests/93), thanks Zhenghao Zhang!

• 2026-03-16 v1.46.2: Upgrade to SQLite 3.51.3.

• 2026-02-17 v1.46.1:

  • Ensure connection state is reset if Tx.Commit fails. Previously, errors like SQLITE_BUSY during COMMIT could leave the underlying connection inside a transaction, causing errors when the connection was reused by the database/sql pool. The driver now detects this state and forces a rollback internally.
  • Fixes [GitHub issue #2](modernc-org/sqlite#2), thanks Edoardo Spadolini!

• 2026-02-17 v1.46.0:

  • Enable ColumnTypeScanType to report time.Time instead of string for TEXT columns declared as DATE, DATETIME, TIME, or TIMESTAMP via a new _texttotime URI parameter.
  • See [GitHub pull request #1](modernc-org/sqlite#1), thanks devhaozi!

• 2026-02-09 v1.45.0:

  • Introduce vtab subpackage (modernc.org/sqlite/vtab) exposing Module, Table, Cursor, and IndexInfo API for Go virtual tables.
  • Wire vtab registration into the driver: vtab.RegisterModule installs modules globally and each new connection calls sqlite3_create_module_v2.
  • Implement vtab trampolines for xCreate/xConnect/xBestIndex/xDisconnect/xDestroy/xOpen/xClose/xFilter/xNext/xEof/xColumn/xRowid.
  • Map SQLite’s sqlite3_index_info into vtab.IndexInfo, including constraints, ORDER BY terms, and constraint usage (ArgIndex → xFilter argv[]).
  • Add an in‑repo dummy vtab module and test (module_test.go) that validates registration, basic scanning, and constraint visibility.
  • See [GitLab merge request #90](https://gitlab.com/cznic/sqlite/-/merge_requests/90), thanks Adrian Witas!
