Subject: Version 1.1.1:
X-Git-Tag: version_1_1~8
X-Git-Url: https://git.p6c8.net/devedit.git/commitdiff_plain/28fffadb645ec8948406c30e05eed0d3776a5cad?ds=inline

Version 1.1.1:
- Improved constructor
- If we tried to unlock the list file and the lock file already exists, the 'lock' variable in the object properties wasn't set to 0
- Fixed a lot of typos
- Removed $VERSION variable (version number is now found in the head comment)
