  "message": "Micro-optimize transitive depencency hash calculation (#20798)\n\nIn small incrementals runs targeting a very large code base, the\n`transitive_dep_hash` function used up to 9% of total CPU.\nMicro-optimize it by avoiding json dump, dict construction and `hex()`\ncalls.\n\nI\u0027ll verify that this helps after this has been merged, but the improved\nperformance (esp. without orjson) seems very likely.",
