ugrep v1.5.3

Faster concurrent output and faster -z (decompression) with a decompression thread. Next release will improve the speed of line-by-line matching (i.e. when not using one of -o, -c, -l, -N, -q) that slows down -z.

ugrep v1.5.2

Simpler build steps (self-contained) and faster option -z.

ugrep v1.5.0

Added multi-threading with lock-free job stealing for high performance. Requires RE/flex 1.4.3 or greater.

ugrep v1.4.4

New and improved --format fields for custom output, updated --json and --xml, faster search for patterns beginning with optional repetitions, such as .*, which requires RE/flex v1.4.2.

ugrep v1.4.3

Added group captures %1 to %9 to --format to customize output, requires option -P Perl matching.

ugrep v1.4.2

New options --cpp, --csv, --json, --xml, --format, updated manual page with section on FORMAT with instruction on how to customize the output.

ugrep v.1.4.1

Optimizations and other improvements. Requires RE/flex 1.4.1 or greater.

ugrep v.1.4.0

More optimizations for faster search. Requires RE/flex 1.4.0 or greater. Binaries for Linux/Windows/MacOS included.

Improved mmap performance and other performance enhancements based on RE/flex v1.3.8.

ugrep v1.3.7

Added mmap(2) and other speed improvements, improved GNU/BSD grep compatibility.
