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 ralger?

ralger stopped scraping only web pages and started scraping the files on them.

ralger is a scraping package that wraps rvest behind task-named functions — titles_scrap(), table_scrap(), images_scrap() and so on — aimed at users who want data out of a page without writing selector logic. After four years of quiet it returned in 2.3.0 with a different kind of function: readers for PDF, XLS, XLSX and CSV files, plus comment extraction.

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.

ralger stopped scraping only web pages and started scraping the files on them.

◆ Current state

ralger is a scraping package that wraps rvest behind task-named functions — titles_scrap(), table_scrap(), images_scrap() and so on — aimed at users who want data out of a page without writing selector logic. After four years of quiet it returned in 2.3.0 with a different kind of function: readers for PDF, XLS, XLSX and CSV files, plus comment extraction.

◆ Where it's heading

The earlier arc was about making HTML scraping survive contact with the real web — wrapping every function in tryCatch so a dead link or missing connection returns NA with a message rather than an error, adding case-sensitivity control, widening heading extraction to h3. The 2.3.0 additions change the target rather than the robustness: the unit of interest becomes the document a page links to, not the page itself.

◆ Prediction

If the file readers follow the pattern the image functions set, expect preview-and-batch companions next — images_scrap() arrived alongside images_preview() for exactly that reason. The four-year gap before this release makes timing unpredictable.
