From Scott Cain:
I’ve just released Chado 1.23. This is a bug fix release with no changes to the schema from the 1.22 release. If you are upgrading from Chado 1.2 or later, installing this bug fix release is easy; type the following commands:
perl Makefile.PL
make
sudo make install
If you’re installing from before Chado 1.2, you can add
make update
which should update the schema (after backing up your database, of course). See Updating Chado for more information. Chado 1.23 can be downloaded from SourceForge.
Here are the changes from the last release:
