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 OSRM?

OSRM 26.9.0 routes through pedestrian areas and plazas for the first time.

OSRM 26.9.0 delivers native pedestrian area routing using mesh triangulation and visibility graph computation. Routes can now originate from any point inside a pedestrian area, plazas up to 256 vertices are solved at query time, and table/trip queries across plazas work consistently with standard routing. A bicycle turn-restriction fix and POST support for the nearest API also ship in this release. The 26.8.0 release that preceded it was maintenance-only.

Bun vs OSRM: editorial side-by-side

B
Bun
DEVOPS
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.

OSRM 26.9.0 routes through pedestrian areas and plazas for the first time.

◆ Current state

OSRM 26.9.0 delivers native pedestrian area routing using mesh triangulation and visibility graph computation. Routes can now originate from any point inside a pedestrian area, plazas up to 256 vertices are solved at query time, and table/trip queries across plazas work consistently with standard routing. A bicycle turn-restriction fix and POST support for the nearest API also ship in this release. The 26.8.0 release that preceded it was maintenance-only.

◆ Where it's heading

OSRM has been investing in routing fidelity for complex urban geometries. Plaza/area routing represents a conceptual expansion beyond edge-and-node graph routing to area-based routing — a hard computational problem that the team has approached incrementally. The POST support expansion is modest but signals an interest in API flexibility for programmatic use cases.

◆ Prediction

Expect stability and edge-case fixes for the new area routing code in subsequent patches — the mesa triangulation solver is new and will encounter production edge cases. POST support expansion to other endpoints is a likely follow-on.
