v6.9 was out at the start of Dec & had lots of updates for #RiverLea - https://lab.civicrm.org/extensions/riverlea/-/blob/main/CHANGELOG.md?ref_type=heads ahead of a big variable rename coming in 6.10.

The most user-facing change is a UX to change the font-size for any Stream (aka sub-theme). This started with two complaints at the #CiviSprint in Lunteren that River's #accessible 1rem/16px font size was annoying. Andreas from Stiftung Pfadfinden was looking for a sprint activity, so added a select-list with some help from core team on how to do safely.
