Hi and first of all: thank you so much for this beautiful piece of software! I hope I'm addressing this correctly here: Since around 3 years, I've always (happily) downloaded the newest Windows Pd versions from http://msp.ucsd.edu/software.html ... the current version irritated me a bit though since it doesn't seem to include all the changes that I've been following on github.
I downloaded and checked the installer and the zipped version. When I open "Help"->"About Pd" from the menu, it says "Pd version 0.53.0". Since that might just be a missing manual edit, I checked for changes in help files and .tcl files that should be present (sigmund~-help.pd for example) and can confirm that these are also missing in the installer and zip of Pd0.53-1. I then built the current release myself from https://github.com/pure-data/pure-data/releases/tag/0.53-1 and everything looks correct now (including "About Pd").
I hope I didn't do anything wrong on my side - but otherwise, I hope this might help to get the downloads fixed. All the best! Ben
