  "summary": "New bilingual blog post summarising September's open-toolchain work. It covers the regional-clock chain: nextpnr-xilinx #170, #171 and #205 are merged, and prjxray-db #30 is open. It covers the himbaechel ports nextpnr #53-#58 (only #58 merged) and the demo-projects #22 regression designs. It also covers the PERFCLK segbits rows rendered from a .t27 spec (146/146 rows, 7/7 tests), which surfaced a t27 compiler parse bug (gHashTag/t27#5593, fix in #5594). Counts were measured through the GitHub API on 2026-10-02. Open PRs are labelled open, and bot approvals are not counted as maintainer reviews.",
