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 pgBackRest?

pgBackRest tracks PostgreSQL 19 beta by beta, patching the hangs it finds along the way.

pgBackRest is in the tail of the 2.59 cycle, which brought PostgreSQL 19 support and restricted every command except restore from running as root. The 2.59.1 patch keeps step with PostgreSQL 19beta3 and clears three defects, including a hang that occurred whenever the chunk buffer was smaller than the input buffer. Release cadence remains a few feature releases a year with patches slotted between them.

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.

P5.0

pgBackRest tracks PostgreSQL 19 beta by beta, patching the hangs it finds along the way.

◆ Current state

pgBackRest is in the tail of the 2.59 cycle, which brought PostgreSQL 19 support and restricted every command except restore from running as root. The 2.59.1 patch keeps step with PostgreSQL 19beta3 and clears three defects, including a hang that occurred whenever the chunk buffer was smaller than the input buffer. Release cadence remains a few feature releases a year with patches slotted between them.

◆ Where it's heading

Two currents continue. Support for the next PostgreSQL major arrives experimentally a full release before it is needed — 18 in 2.55.0, 19 in 2.59.0, and now tracking 19's betas point by point — so the backup tool is ready before the database ships. The second is a move away from ambient privilege and toward cloud-native identity: managed identities and pod identity in place of stored keys, and the root restriction narrowing what a compromised invocation can reach. The 2.59.1 fixes are the ordinary cost of that pace, including a packaging fault in the GitHub source archives.

◆ Prediction

Expect the beta-tracking patches to continue through PostgreSQL 19's release cycle, with the next feature release arriving after 19 goes final rather than before it.
