@Jakuje: As I've understood it, the Adventure Lab app is a new way to search for and log lab caches, but this is not a new type of lab caches. The previous web-based way to handle lab caches will be discontinued. Recently, some COs were given the opportunity to create a lab cache (and it seems that this will happen again), but this was not the first time this happened. A few years ago, many (everyone?) could create a lab cache on, IIRC, Valentine's Day which is why my hide stats include a lab cache.
