Discovered “bugs”in a software/firmware design aren’t necessarily discussed in detail if they aren’t global across a vast majority of units or were voiced by a user that has the potential to morp into something bugger. In that case companies will make the announcement just to get out infront of it before someone tries to escalate it into something bigger.
Others are bugs that were known at the time of a roll-out but were not serious enough to derail release. Those are handled in an update such as X.1.
Some are just annoyances that the engineers discover after rollout testing or crop up during the resolution of another fix.
Apple, Microsoft and Android to name a few follow the same line of general silence when pushing out “bug” fixes.
In short “why make a mountain out of a mole hill”.
Note: In most cases not installing the updates have a more adverse effect on systems and/or will prevent the user from moving forward with future updates/enhancements. In some cases updates that appear to make things worse are often due to peripheral hardware that needs to be updated as well. Routers are a prime example. On the subject of routers (or network design) some are just not compatible with Sonos.
