Version 3.0 beta

I think version 3 is ready to be released into the wild. However, I like to wait and see if there are some testers who are willing to provide feedback, maybe detect remaining bugs, …

\usepackage{acro}

is the same as

\usepackage[version=3,upgrade=true]{acro}

Testing isn't even that brave, there is

\usepackage[version=2]{acro}

which loads the last version that has been released to CTAN prior to version 3.

v3.0 alpha-2

This is an early release of version 3.0 of acro – published for pre-tests only. This pre-release includes various fixes over the last pre-release and significant parts of the manual written.

If you want to test the new version use '\usepackage}[version=3]{acro}or no option at all. Withversion=2you get the old version ofacro. Using \usepackage}[version=3,upgrade]{acro}` is supposed to give as much meaningful warnings and errors as possible.
