 This page features all the experimental branch releases. Our experimental branch are usually updated multiple times a day and typically are perfectly safe to play, but you might want to back up your saves just in case we introduce a feature that will be changed during testing. Here are the changes since the last stable release:
 
+# 1.52.15: 
+
+* The exact mineral composition of all the ore chunks you collect and process is now stored in your save file. Previously, the game relied on procedural seed to re-create the same composition after interlunar transit, but this approach proved to be inaccurate - especially if you had partially-processed chunks in your cargo hold.
+
+Feedback Focus: Save compatibility. This release modifies the way your game saves data, and while I took extra steps to provide both forward and backwards compatibility, please look out for any save-related glitches.

 # 1.52.13:
 
 - If you collected a weregild and the captain you were processing felt like explaining themselves, they got distracted and did not remember that they paid you, allowing you to ask for money a second time.
