+		{
+			change = What's Changed
+			subchange = Remove Orbital Recovery contract mentioning it can be completed twice
+			subchange = Add a patch so that Kerbalism uses the actual inclination of a vessel when checking if an experiment could run (inclination was wrong for vessels not around the current body when Principia is installed due to how Principia implements axial tilt)
+			subchange = Add Astronaut Complex upgrade requirements to Early X-Planes and Early Crewed Orbit to signpost that upgrades to the AC will be needed
+			subchange = Fix various tips etc. that mention Astronaut Complex levels
+			subchange = Fix an issue where UI state could sometimes not be restored properly after closing a popup
+			subchange = When building a new LC that does not perfectly share commonality with an existing LC, its commonality percent is capped at 95%. This fixes an issue where LCs could be upgraded bit by bit with no efficiency loss
+			subchange = Highlight (in yellow) when the desired max mass for an LC is above the maximum possible modify limit (or below the minimum possible modify limit)
+			subchange = Fix an issue where RP-1 would hang on launch if KSPWheel was not installed
+			subchange = Fix lingering references to Renovate and Upgrade rather than just Modify for LCs
+			subchange = Update Kerbalism patches to match the existing Kerbalism PRs and make sure they will not be applied to forthcoming Kerbalism releases which have the PRs merged
+			subchange = Improve the Install Checker's text to be clearer that the issue could be either missing or outdated dependencies when RP-1 doesn't detect its dependencies or itself fails to load
+			subchange = Add support for new ROC docking ports
+			subchange = Add optional orbit contract to Crewed Lunar program
