Shimano just introduced a new reworked update to their budget Acera mountain bike groupset, which will now also be offered in a separate trekking-specific variant as it’s become quite a popular spec in that segment. Shifting stays with 9 speeds like the previous Alivio/Acera generations, but gets updated to a new Mega 9 Lite that sees some optimization. The big difference is of course the upgrade to a Shadow rear derailleur for the lower profile, which was developed with more aggressive riding in mind. The front derailleur cage also gets reshaped for better shifting and gets a slightly more compact clamp and link layout that could shed a tiny bit of weight, all while improving tire clearance.
