Igir v4.3.2 is released. A zero-setup ROM collection manager that sorts, filters, extracts or archives, patches, and reports on collections of any size on any OS.

Igir Changelog:
This release addresses some user-submitted bugs & feature requests.
Feature: --patch-only option
The option lets you write only patched ROMs, skipping all others.
Thank you @noah978 for the suggestion!
Feature: --trim-scan-files option
The option lets you always or never scan files not inside archives. --trim-scan-files never can help speed up your processing time if you know you definitely don't have any trimmed ROMs.
Thank you @HeroponRikiBestest for the suggestion!
Feature: handle region variants for {emulationstation} and {romm}
Some ROM frontends differentiate regional variants of consoles, such as:
NEC PC Engine vs. TurboGrafx
Nintendo NES vs. Famicom
Sega Genesis vs. Mega Drive
Igir will do its best to pick the right one based on DAT information.
