 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 introduced a feature that will be changed during testing.
 
+# 0.577.6:
+- Updated geologist filter. When having the "unmarked" option turned on, the affected systems will be allowed to act upon matching ore, even when it's not apprised yet. Disabling the "unmarked" option will enforce stricter checking, and ore that is not apprised yet will not be counted as a valid target. This changes the behaviour of drone systems and the AR1500 manipulator. If you want your systems to work on the ore that is still being apprised, turn on the "unmarked" option for them.
+- Fixed a bug in the tutorial, which would sometimes skip ahead without player input if the previous action took much longer than anticipated.
+- A tutorial step that requires you to target an ice asteroid or ore chunk will now spawn a relevant item nearby if there is none near.
+- The tooltip for control settings for the excavator will now explicitly mention that double-tap causes it to stay open.

 # 0.577.1:
 - The language selection menu will now show both the native language name as well as an English version of it.
 - Changed the geologist filter behaviour for filters of minimum chunk value. Since the composition and value estimations were not happening simultaneously, hardware configured to interact with unidentified chunks and chunks above specified value had a time window in which the ore was identified for content, but not yet appraised. This caused your AR1500 manipulator to briefly release chunks while they were apprised, as well as the new ore marker filter to toggle the labels in and out as the ore was being appraised.
