Welcome! And congrats! An upgrade can drive one nuts ... especially with plugins that might not be compatible with the version one is upgrading to. Been there ... done that! :\
Since the environment check doesn't check addons/plugins, I've a script using moosh that I've called 'checkaddons' that I run to see if there are updates to the plugins.
echo 'Add-on listing: ';
for i in `cat ./addons.txt`
echo "Addon in que: $i";
moosh -n plugin-list |grep $i
The addons.txt file is nothing more than a text file that list the shortnames of the addons:
Example of addons.txt:
Output of script looks like:
Addon in que: mod_hvp
Addon in que: mod_questionnaire
Addon in que: mod_customcert
I can then acquire the zips via wget and be prepared for 'events' on updates/upgrades of the site.
