ugrep v1.6.2

Added .Z format decompression with option -z and new option --glob=GLOB (shorthand -g GLOB), moved old option -g to -u (--ungroup). Decompression of .Z formatted files (compress format) requires BSD funopen. Option .Z will be made portable in the next release with a built-in decompressor.

ugrep v1.6.1

Added searching tar and pax archives compressed with bzip2 and xz/lzma to option -z; improved color display output (option --color) when backgrounds are used.

ugrep v1.6.0

Added tar file search (tarballs and compressed tar files) with option -z. Supports tar format v7, ustar, and old gnu tar, as well as pax extended headers blocks for long file names, which pretty much covers all common use cases. Matching files located in tarballs are output in { } braces, suffixed to the tar file name. Fixed minor matching line display issues.

ugrep v1.5.13

Improved option -X and faster termination when output stream closes early.

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.
