Build date from 2019

Its strange that the build date shows 2019 even though i have the latest beta version

Build date does not mean download date or installation date on your PC.
Please take a look at Devlog of AmiBroker.

It (version 6.30.5 final release) was built and released Mar 18th 2019. So it is same date as in your picture.
So not sure which other date you expect to see there.

If you mean AB 6.35.0 beta then you should download and install this version from here

You possibly downloaded and installed different version than your expect.

hahaha. guess i am getting blind. or its a friday today
