1.99.55.25130 went up a few days ago which has the changes for all of the problems that I was able to replicate when it comes to streaming (as long as the needed plug-ins are able to be loaded i.e. as long as smart app control isn't blocking the likes of in_url).
There's also so many old radionomy & listen.shoutcast stream urls being provided despite none of them working for many years as of this reply...
The internet radio cache which any of the builds is provided has had some changes made to how it's generated over the last few days which filters out the ~36K of 'dead' streams that the shoutcast directory is providing which leaves around 7-8K of seemingly valid streams depending on when things are queried during the day. Alas I can remember when that had a legit 50K+ or internet streams & am surprised that the api is still even running considering that's a massively small number of streams vs icecast + radiobrowser. That's why for those paying attention the internet radio view has dropped from over 100K results to ~68K results.
Whether that increased filtering of the api results relates to the other mention of things not working I don't know but it's the only other thing I've been able to find in addition to the core / url playlist handling problems that affected the prior build.
