I haven't uploaded to the addons for many, many years, but at that time the addons was live instantly it was uploaded. 1.5 was listed in March as has been mentioned on both of my posts. The first as "March", the second I added "7 March" to clarify further (not April). Today the 1.5 addon is still listed as "7 March".
Not sure what happened to your 1.5.5???? or what happened to 1.5.1, 1.5.2, 1.5.3, 1.5.4?
1.5.1 was published yesterday(presumably uploaded yesterday too), and can confirm that dspeak fix is no longer needed.
My post was not trolling just adding to the already reported bug that hadn't been addressed at the time with factually accurate information.
