A Rust rewrite of mergelog 4.5, a C tool from 2000 that merges Apache log files chronologically. Six optimizations — a k-way heap merge, a hand-rolled CLF parser, String buffer reuse, mimalloc, 4 MiB read buffers with SIMD newline search, and zstd support — took the Rust binary from slower than the original to 2.26× faster.

AWFFull 4.0.0 brings a long-overdue overhaul to a C-based web server log analyser forked from Webalizer: PCRE2 replaces EOL libpcre, libmaxminddb replaces the deprecated GeoIP .dat format, new ASN statistics show traffic by network operator, and optional Intel Hyperscan, mimalloc, and XXH3 deliver measurable performance gains on large logs. The release also adds a full GitLab CI/CD pipeline, .deb/.rpm packages, a multi-stage container image, updated browser and bot detection lists, and 100%-complete translations for 6 languages.
