([#348](https://github.com/simonw/sqlite-utils/issues/348))\r\n-   New Python methods for running `ANALYZE` against a database, table or index: `db.analyze()` and `table.analyze()`, see [Optimizing index usage with ANALYZE](https://sqlite-utils.datasette.io/en/stable/python-api.html#python-api-analyze). ([#366](https://github.com/simonw/sqlite-utils/issues/366))\r\n-   New [sqlite-utils analyze command](https://sqlite-utils.datasette.io/en/stable/cli.html#cli-analyze) for running `ANALYZE` using the CLI. ([#379](https://github.com/simonw/sqlite-utils/issues/379))\r\n-   The `create-index`, `insert` and `update` commands now have a new `--analyze` option for running `ANALYZE` after the command has completed. ([#379](https://github.com/simonw/sqlite-utils/issues/379))\r\n-   New [sqlite-utils bulk command](https://sqlite-utils.datasette.io/en/stable/cli.html#cli-bulk) which can import records in the same way as `sqlite-utils insert` (from JSON, CSV or TSV) and use them to bulk execute a parametrized SQL query. ([#375](https://github.com/simonw/sqlite-utils/issues/375))\r\n-   The CLI tool can now also be run using `python -m sqlite_utils`. ([#368](https://github.com/simonw/sqlite-utils/issues/368))\r\n-   Using `--fmt` now implies `--table`, so you don't need to pass both options. ([#374](https://github.com/simonw/sqlite-utils/issues/374))\r\n-   The `--convert` function applied to rows can now modify the row in place. ([#371](https://github.com/simonw/sqlite-utils/issues/371))\r\n-   The [insert-files command](https://sqlite-utils.datasette.io/en/stable/cli.html#cli-insert-files) supports two new columns: `stem` and `suffix`. ([#372](https://github.com/simonw/sqlite-utils/issues/372))\r\n-   The `--nl` import option now ignores blank lines in the input. ([#376](https://github.com/simonw/sqlite-utils/issues/376))\r\n-   Fixed bug where streaming input to the `insert` command with `--batch-size 1` would appear to only commit after several rows had been ingested, due to unnecessary input buffering.
