Release Highlights

Features

• BZip2, DEFLATE64, Implode, LZMA, PPMd, Shrink, and xz compression are now all supported for zip archives via 7zip.
• Split archives (.7z.001, .zip.001, etc.) are now supported via 7zip.
• Split files (.iso.001, .chd.001, etc.) are now supported via 7zip.
• Signature detection has been added for Front Fareast copier headers (Super Wild Card, Magic Super Griffin, Super Magic Drive). Thank you, @ndomako10, for the PR!

Optimizations

• @terafin greatly sped up the code that checks for excess files within matched archives.

Fixes

• @terafin fixed ROMs being dropped when applying --merge-roms <mode> on MAME software list DATs.
• File de-duplication and conflict detection now use file paths instead of checksums. Thank you, @fooness, for the bug report!
• --merge-discs now preserves game metadata, such as category information. Thank you, @j9ac9k, for the bug report!
• Report CSVs now correctly have their header written when all ROMs have been filtered out by filter rules. Thank you, @pasnox, for the bug report!
• Invalid parent/clone DATs that specify a nonexistent parent now correctly re-elect a new one. Thank you, @ulinvega, for the crash report!
• Using the report command alone without any writing commands now verifies archive entry names the same as writing would. Thank you, @dirctbe, for the bug report!
