Original WLED 13.2 SW?

Hi,

where can i download the original Athom WLED v13-2 (i think) that came with WLED ESP32 Music Addressable LED Strip Controller???

after updating the remote does not work anymore with more that 650 LED! 648 or so seems to be a maximum?! i used a own ir.jason (JSON Remote) file and remapped all keys. with the original SW this works fine with 1400 LEDs. with any update this doesn't works anymore..
