Yeah, that’s been happening a lot lately the regulations for drones and model aircraft have tightened up in many places, especially around airports, controlled airspace, and heavier units (over 250g or 2kg, depending on the country).
The changes you’re referring to sound like updates to the UAS (Unmanned Aircraft System) or model aircraft regulations that define new no-fly zones or expanded controlled airspace buffers. Many aviation authorities (like the CAA in the UK, FAA in the US, or EASA in the EU) have been refining these rules with pretty short notice.
