What is Bun?

Bun is rewriting its core from Zig to Rust while shipping built-in APIs at a monthly clip.

Bun ships a substantial point release roughly monthly, each widening Node.js compatibility and folding more capability into the runtime itself — image processing, Markdown parsing, cron, archives, a headless WebView, HTTP/2 and HTTP/3 clients. Performance work is constant, with double-digit speedups landing release over release. In July the team disclosed it is rewriting Bun's implementation from Zig to Rust.

What is SimpleSAMLphp?

SimpleSAMLphp advances two maintenance branches in lockstep, security patches first.

SimpleSAMLphp is maintaining the 2.4 and 2.5 lines in parallel and patching both from the same fixes. Six releases since late May split into two security releases — the 2.4.6/2.5.1 pair on 29 May and 2.5.3 on 10 August — and four bugfix releases. Release bodies carry only download links and SHA256 checksums, so the substance sits in the linked changelog rather than the feed itself.

Bun is rewriting its core from Zig to Rust while shipping built-in APIs at a monthly clip.

◆ Current state

Bun ships a substantial point release roughly monthly, each widening Node.js compatibility and folding more capability into the runtime itself — image processing, Markdown parsing, cron, archives, a headless WebView, HTTP/2 and HTTP/3 clients. Performance work is constant, with double-digit speedups landing release over release. In July the team disclosed it is rewriting Bun's implementation from Zig to Rust.

◆ Where it's heading

Two arcs run in parallel: keep absorbing what developers reach for third-party packages to do, so the runtime is batteries-included, and re-lay the foundation in Rust for a larger contributor pool and easier maintenance. The near-term feature cadence has not slowed, which suggests the rewrite is incremental rather than a hard fork.

◆ Prediction

Expect continued monthly 1.3.x releases centered on Node compatibility and built-in APIs, with the Rust migration surfaced through engineering write-ups before it changes anything user-facing.

S5.0

SimpleSAMLphp advances two maintenance branches in lockstep, security patches first.

◆ Current state

SimpleSAMLphp is maintaining the 2.4 and 2.5 lines in parallel and patching both from the same fixes. Six releases since late May split into two security releases — the 2.4.6/2.5.1 pair on 29 May and 2.5.3 on 10 August — and four bugfix releases. Release bodies carry only download links and SHA256 checksums, so the substance sits in the linked changelog rather than the feed itself.

◆ Where it's heading

The dual-branch discipline is the story: every advisory lands twice, once per supported line, which is what a SAML library embedded in long-lived identity deployments has to do for operators who cannot jump minor versions on demand. The May advisories touched HTTP-Artifact resolution and SP-Proxy setups bridging IdPs of differing trust levels — federation's sharp edges rather than everyday login flows. No feature work is visible in this window; 2.5.0 in March was the last minor.

◆ Prediction

Expect both branches to keep advancing together, with 2.4 receiving anything 2.5 gets on the security side. The feed offers no signal on when a 2.6 line might open.
