Gzip 1.15 fixes decades-old correctness and safety bugs

Gzip 1.15 (September 20, 2026) includes more than 100 commits, largely bug fixes accumulated over the past 18 months. The release fixes a race that could remove the wrong file after an ancestor rename, uninitialized-memory use, an LZH decompression buffer overflow, multiple LZH corruption cases, streamed ZIP handling, temporary-file races on limited platforms, and locale handling for diagnostics. It also drops several obsolete platform targets.
