[suggestion] The banner now says 11 platforms and the ABI list adds
armhf, but two later sections of the same README were not updated. Line 192 still says pre-built libraries cover "9 ABIs total: 4 Linux, 2 macOS, 3 Windows" (actual set is 6 Linux + 2 macOS + 3 Windows). Line 222 still says CI builds "all 9 supported platforms" and lists Linux as AMD64, i386, ARM32, and ARM64, omitting botharmhfandriscv64.Suggestion: Update those two sentences to the same 11-ABI set the banner, the platform list, and
create-releasenow use, includingarmhfin the Linux CI list.
