📋 Changes

• This release fixes a read overflow in the -pm2- decoder, where a specially-crafted -pm2- sequence could cause reads from beyond the end of the `copy_decode[]` array. However, it is not believed to be an exploitable bug so this is not a security issue. Thanks to Yukimura / @damseleng for reporting the bug.
• Archived files with empty filenames are now skipped over during extract so that subsequent files can be extracted properly. This allows some files in the Aminet archive to be extracted that were previously only partially extracted (thanks @polluks).
• A minor typo was fixed in the `lha_reader.h` header (thanks @polluks).

📋 Changes

• The output from the list subcommands has been tweaked to be more consistent. This should help to avoid parsing bugs with naively-written programs and scripts that parse the list output. This includes various GUI tools.
• The test suite was expanded to include archives generated by Tascal Lha (a Windows CE port); LH/2 (an OS/2 port); ExpLZH; and the port of Lha that ships with MorphOS.
• A workaround was added for a bug with the Amiga port of lha that causes some versions to generate malformed archives where directories are stored using the -lh0- compression type. Thanks to @zzarko, @polluks, @alfredone and @jsummers for their work on figuring out the bug.
• Support was added for the 64-bit file sizes header, allowing huge files (>=4GiB) generated by the MorphOS port of lha to be extracted correctly.
• The compression ratio shown in list output now always rounds up to the next 0.1%, which is a more pessimistic but more honest. For example, very highly compressed files might be shown as "0.1%" of their original size, but never "0.0%".
• The manual page now includes more detailed information about the different list subcommands.
• The liblhasa headers are now installed into a directory with a name that accurately reflects the project's version number.
• The liblhasa .so version numbers now have meaningful numbers.
