It was then renamed to LHA to avoid conflicting with the then-new MS-DOS 5.0 LH ("load high") command.

The original LHA and its Windows port, LHA32, are no longer in development because Yoshizaki is busy at work.

[2] It was used by id Software to compress installation files for their earlier games, including Doom and Quake.

This was due to Aminet, the world's largest archive of Amiga-related software and files, standardising on Stefan Boberg's implementation of LHA for the Amiga.

Files using larger numbered methods may as well not exist, as Jared only considers them planned features.

LArc uses the same file format as .LZH, but was written by Kazuhiko Miki, Haruhiko Okumura and Ken Masuyama, with extension name ".LZS".

[9] Because of a bug, DOS time stamps from Level 0 and 1 headers after the year 2011 will be set to 1980, meaning that some utilities need to be patched.

Two problems could emerge from this scenario: a buffer-overrun may occur for naive implementations assuming a 4KB max size from the original specification; antivirus software may skip over files with such large headers and fail to scan for a virus.
