RIM is still working on the Podcasts app that has bee relatively well received by users. Blaze spotted this latest update to v188.8.131.52 that was released with no change log.
If you use the Podcasts app often I would recommend heading to App World and updating to 184.108.40.206 just to be safe. RIM does not usually release these incremental updates unless there was an annoying bug they wanted to fix that did not make it in the main release.
Let us know if you spot any differences!
