What is Libreswan?

Libreswan puts post-quantum key exchange into IKEv2 — ML-KEM 768 ships in v5.4.

Libreswan spent the last two releases on security patches, including a CVE found when the project ran an AI audit over its own codebase. v5.4 breaks that pattern: it implements RFC 9370's multiple-key-exchange machinery end to end — IKE_INTERMEDIATE, IKE_ADDITIONAL_KE and IKE_FOLLOWUP_KE — and uses it to carry ML_KEM_768 in IKE_SA_INIT and IKE_INTERMEDIATE. The rest of the release is a wide maintenance sweep across kernel integration on the BSDs, config parsing and logging.

What is string2path?

A Rust-backed glyph-to-path converter swapped font engines and picked up variable fonts.

string2path turns text rendered in a font into data frames of path, fill or stroke coordinates that R can plot directly. The 0.3.0 release migrated the underlying Rust stack to fontique and skrifa, which brought variable font support and let font_weight accept numeric values, at the cost of dropping WASM. The 0.3.1 patch that followed is entirely build fixes for Intel macOS and link-time optimization flags.

Libreswan puts post-quantum key exchange into IKEv2 — ML-KEM 768 ships in v5.4.

◆ Current state

Libreswan spent the last two releases on security patches, including a CVE found when the project ran an AI audit over its own codebase. v5.4 breaks that pattern: it implements RFC 9370's multiple-key-exchange machinery end to end — IKE_INTERMEDIATE, IKE_ADDITIONAL_KE and IKE_FOLLOWUP_KE — and uses it to carry ML_KEM_768 in IKE_SA_INIT and IKE_INTERMEDIATE. The rest of the release is a wide maintenance sweep across kernel integration on the BSDs, config parsing and logging.

◆ Where it's heading

The post-quantum work is the spine of this release and it is not experimental framing — it is standards-track RFC 9370 plus a hard dependency on NSS 3.118.1, meaning distributions have to move their crypto library before users can turn it on. Around it, the project keeps grinding on operator experience: better proposal parsing, more specific error messages, traffic selectors and DIGSIG algorithms in logs, and rate-limited logging. Experimental flags for subnet leasing and updown-config suggest the next capability additions are already staged.

◆ Prediction

Expect ML-KEM to move from supported to recommended in default proposals once NSS 3.118.1 is widely packaged, and the experimental leftaddresspool subnet leasing and per-connection debug options to stabilize in a following release.

S0.0

A Rust-backed glyph-to-path converter swapped font engines and picked up variable fonts.

◆ Current state

string2path turns text rendered in a font into data frames of path, fill or stroke coordinates that R can plot directly. The 0.3.0 release migrated the underlying Rust stack to fontique and skrifa, which brought variable font support and let font_weight accept numeric values, at the cost of dropping WASM. The 0.3.1 patch that followed is entirely build fixes for Intel macOS and link-time optimization flags.

◆ Where it's heading

Most of this package's release history is the cost of shipping Rust through CRAN — ARM Linux build errors, crate updates, deployment target mismatches on M1, installations without shared libraries, and repository policy compliance. The feature work that does land tracks font technology rather than R-side API design: partial COLRv1 color emoji in 0.2.0, variable fonts in 0.3.0. The maintainer is also candid about correcting earlier mistakes, having removed a path_id column after concluding its calculation had never been right.

◆ Prediction

Expect the skrifa migration to keep paying out in font format coverage, with COLRv1 clip and layer composition the obvious gap now that a more capable backend is in place.
