v2.0.1

• Fix bugs.
• Improve I/O performance.

Since 2.0.0, the file format is no longer compatible with 1.x. See the release note of 2.0.0.

v2.0.0

THIS IS A BREAKING CHANGE FROM 1.x.

• Instead of blank lines, the card separator is %% on a line by itself now; In fact, any line starting with % is designated as a card separator, but %% is recommended.
• Provide the -1 option to convert old files. (See the Migration from 1.x section in README.md)

The rationale behind this change is to make it easier for awkand other programs to parse input files.

The bug was in ctab.c/dumpctab().

after that the backup has been created,
dumpctab() falsely returned successfully.
