 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.
 
+# 0.620.1:
+- Railguns can no longer be installed on docking bays and drone hardpoints. You can refund the railgun purchase if you have a save with such an illegal configuration.
+- Re-balanced some weapon repair costs and times. Weapons that are, according to the game lore, established on the market and have easy access to replacement parts will now be much cheaper to repair - but the repairs will take longer to represent the time required to adjust to subtle differences in available aftermarket replacement parts.
+- Railgun based massdrivers are now less accurate than coilgun-based ones.
+- Railguns and salvage manipulators will wear out less now.
+- NDCI firing solution projection will now take into account the projectile spread of damaged massdrivers.
+- Improved performance of projectile rendering.
+- Fixed a leak that caused projectiles that don't hit anything to be simulated indefinitely, possibly degrading performance over time if your playstyle included missing a lot.
+- Equipment which is not part of the pre-flight inspection will not be marked as "failing" or "passing" inspection on the repair screen.
+- Updated translations.
+
+Feedback Focus: Still looking for feedback on massdriver damage balance and combat balance.

 # 0.619.0:
 - Ships now remember the crew you assigned to them and will switch to your preferred crew when you pick them, if available.
 - Texts displayed on the information billboard in your docks will no longer jump around when preparing to play video.
