This is a bugfix release. Mainly issue [#9 ] with wrongly named option and command has been fixed. The version number has been changed to 1.2 (instead of 1.1b only), because renaming an option and commands can always cause incompatibilities and users should change existing documents using the deprecated option or command name. So if you use option sience, please replace it by science. If you use command \sience please replace it by \science. If you have defined a title page style using the internal macro \@sience, please replace it by \@science.
This release should be available at CTAN and afterwards via TeX Live package manager(s) and MiKTeX console soon. Updating using the appropriate tool of your TeX distribution is recommended.
