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 Devin?

Devin's quarter is one long enterprise hardening push, headlined by stacked review permissions and network policy.

Devin is Cognition's autonomous software engineer, and the last six weeks of releases are almost entirely about making the agent enterprise-deployable. Admins now get tiered PR Review access levels, network policies that constrain Devin's outbound traffic, IDP group management, repo-permission decoupling, SSO connection picking, sensitive-value toggles for secrets, and an enterprise commit-email lock for audit consistency. The pace of incremental UX work — blueprint editor revamp, theme selector, sidebar performance — continues alongside, but it's not the headline.

Bun vs Devin: 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.

6.3

Devin's quarter is one long enterprise hardening push, headlined by stacked review permissions and network policy.

◆ Current state

Devin is Cognition's autonomous software engineer, and the last six weeks of releases are almost entirely about making the agent enterprise-deployable. Admins now get tiered PR Review access levels, network policies that constrain Devin's outbound traffic, IDP group management, repo-permission decoupling, SSO connection picking, sensitive-value toggles for secrets, and an enterprise commit-email lock for audit consistency. The pace of incremental UX work — blueprint editor revamp, theme selector, sidebar performance — continues alongside, but it's not the headline.

◆ Where it's heading

Cognition is treating enterprise admin surface as the bottleneck rather than agent capability. The cadence reads like a team systematically working through a procurement checklist: identity (SSO, IDP groups), network (egress policies), data (sensitive secret masking), audit (commit email lock, PR digest), and governance (review permissions). MCP integrations and the remote MCP marketplace are growing in parallel as the connection layer to enterprise tooling.

◆ Prediction

Expect the next batch to extend the same admin surface into observability and audit reporting — Devin session logs that satisfy SOC/ISO controls, role-based access across the new IDP groups, and likely a managed-private-deployment story for customers who need the agent inside their VPC.
