Happy to see the project is still going!
I am looking to upgrade to 1.6 and am unsure of the process. Is it the same as always, but grab the files from github instead?
Easiest is to use the upgrader script:

or installer stub:

Thank you! Used the stub and it appears to have worked.
(It said depreciated connection method, I choose mysqli but got a critical error when I first tried to log in. But navigating back looks like it triggered something and all seems good)
