ugrep v1.5.11

Task parallel decompression and search of .gz, .bz, .bz2, .bzip2, .lzma, and .xz files with option -z.

ugrep v1.5.10

Fixed windows ugrep.exe job stealing load balancing optimization.

ugrep v1.5.8

Updated patterns, speed improvements, multi-line matching improvements, fixed options -Y and --tabs that were permanently disabled.

ugrep v1.5.7

Added new --format fields and improved --csv, --json, --xml, --cpp output options.

ugrep v1.5.6

Fixed ugrep option -z (decompression) that caused gzdopen() and gzread() failures.

ugrep v1.5.4

Speed improvements, fixed slow -z and reading from pipes.

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.
