February 2026: Delivered OCamltest documentation modernization and build hygiene improvements in ocaml/ocaml. Migrated docs from Org mode to AsciiDoc with asciidoctor HTML, added cross-references to installation/README, clarified command examples with source language annotations, and cleaned formatting (removing leading backticks) with consistent newline termination. Fixed the Makefile recipe for OCamltest manual, stabilizing builds. Result: easier onboarding, reduced support queries, and a maintainable docs stack for future iterations.

January 2026 monthly summary for ocaml/opam-repository focusing on compatibility improvements to enable OCaml 5.4 across ppx_make and ppx_pyformat and the resulting stability gains. The work enhances user flexibility, reduces friction when upgrading OCaml versions, and improves cross-tool interoperability within the opam-repository ecosystem.
