What is Bun?

Bun 1.4.4 adds bun fmt, a built-in Prettier-compatible formatter, two weeks after bun check.

Bun now covers formatting as well as type checking: v1.4.4 ships bun fmt, a Prettier-compatible formatter it says is 3-6x faster than oxfmt, and makes bun check 1.4-7.8x faster on large projects. The same release closes 271 issues, migrates Yarn Berry lockfiles, adds install retries with backoff, and cuts Bun.SQL CPU per query by up to 48%.

What is Nominatim?

The geocoder finished becoming a Python package, then got back to matching addresses

Nominatim releases a minor version every few months with fast hotfixes when an update path breaks. The 4.5-to-5.0 span was structural — becoming a pip-installable Python package, then removing the PHP frontend, bundled osm2pgsql and cmake scripts outright. Since then the work has returned to geocoding quality: a pattern-based postcode parser, building entrances in results, a restructured forward query parser, and separate processing tables for postcodes, interpolations and associatedStreet relations.

6.3

Bun 1.4.4 adds bun fmt, a built-in Prettier-compatible formatter, two weeks after bun check.

◆ Current state

Bun now covers formatting as well as type checking: v1.4.4 ships bun fmt, a Prettier-compatible formatter it says is 3-6x faster than oxfmt, and makes bun check 1.4-7.8x faster on large projects. The same release closes 271 issues, migrates Yarn Berry lockfiles, adds install retries with backoff, and cuts Bun.SQL CPU per query by up to 48%.

◆ Where it's heading

After the Rust rewrite in July and bun check in v1.4.3, Bun is absorbing the remaining steps of a TypeScript toolchain one release at a time. Package-manager reliability work (Yarn Berry migration, retries, faster hoisted installs) shows it is also going after teams still on other package managers.

◆ Prediction

Expect a linter or lint mode next to round out the check/fmt pair, and more lockfile migrations aimed at pnpm and Yarn users.

The geocoder finished becoming a Python package, then got back to matching addresses

◆ Current state

Nominatim releases a minor version every few months with fast hotfixes when an update path breaks. The 4.5-to-5.0 span was structural — becoming a pip-installable Python package, then removing the PHP frontend, bundled osm2pgsql and cmake scripts outright. Since then the work has returned to geocoding quality: a pattern-based postcode parser, building entrances in results, a restructured forward query parser, and separate processing tables for postcodes, interpolations and associatedStreet relations.

◆ Where it's heading

With the packaging migration finished, the project is optimizing the two things operators actually feel — how fast a search resolves and whether continuous OSM updates keep flowing. The 5.3.0 split into dedicated processing tables was explicitly about making updates faster and more reliable, and the two hotfixes that followed within a fortnight show how tightly that path is watched. Query-side work is trending toward recognizing input that is not in the database at all, as the postcode parser does.

◆ Prediction

Expect continued query-parser and update-pipeline optimization rather than new output types, since that is where every release since 5.0.0 has concentrated.
