Important - Read First
If you are upgrading from a version older than v3.0, your lockboxes must be rebuilt as v3.0 removed the .htaccess login and your existing lockboxes WILL NOT work. Sorry for the inconvenience, but going forward this seemed like the best option for people who found the older system confusing.

Also, in v3.0+ duplicate email addresses are not allowed, so when upgrading, only the first active account will be kept, the rest will be deleted.
Upgrade - v2.0 or higher
Download the patch update and follow the instructions in the readme file:
Upgrade - v1.0 ONLY
v1.0 is obsolete and no upgrades are available, sorry.
