Patch 1.64 or development update 1.6 notes copied and pasted from NMS website:
Patch 1.64
Fixed an issue where items could fail to display in the Quicksilver shop.
Fixed an issue where Community Research missions could be given deadlines in the distant future.
Fixed an issue where players could get trapped when getting out of some ship types.
As a temporary measure while investigating a crash on Xbox One X only, we have disabled terrain tessellation.

Fixed an issue where players could fail to be given the blueprints for Hydroponic Trays.
Fixed an issue where players could fail to be given the blueprints for the plants required by the Farmer.
Fixed an issue where players could fail to learn the Circuit Board blueprint at the correct time.
Fixed an issue where NPC missions might return to a building that had no NPCs in them.
Fixed an issue where players could fail to learn the Glass blueprint at the correct time.
Fixed an issue where players could fail to learn the Frigate Fuel blueprints at the correct time.

Missions from the Mission Board or planetary NPCs will now display their mission title on the Galaxy Map instead of their current objective, to help manage destinations when multiple missions are active.
Tessellation can now be enabled in the graphics options on PC.

EDIT: Because my version number changed without a download and installation this appears to be identical to what had been released in experimental over last three days including the announced experimental patch and the subsequent experimental update that did not have any release notes.

I am still getting trapped in the anomaly and freighter while getting out from my ship.... :(

Hello Games does not participate in these forums and are unlikely therefore to even read the GOG forums. They only provide information in the forums for preferred distributors like steam.

Yeah, I klnow. Want other pelayer here to know not to get out of thier exotics in an Anomaly.

Wow with these updates looks the Exocraft went from totally useless to useless.

There is also a new community mission: https://www.nomanssky.com/2018/10/development-update-7/

Community Research Update

Specialist Polo has at last emerged from the most involved data analysis they have ever undertaken – followed up by a more physical challenge in their workshop, crafting a new device to move this mystery forwards. They are exhausted and disoriented, but triumphant: they have identified the exact origin of the logs left by their lost Traveller-friends, ultimately a question of “when”, rather than where.

Polo requests that participating explorers apply this specialised device to a number of transmission devices on a specific world, characterised by oversized flora. They hypothesize that, with the right time-tuning, and well-considered decisions, it may be possible for explorers to influence events occurring outside of the present moment…

We do not see it. We just pulled up acct Games folder. 1.64 is in there, but not 1.65, not knowing versions is a unnecessary burden. No newer version chicklet, either. Please update us, when 1.65 truthfully goes LIVE. Thanks. Much awaited, as 1.64 has borked more than it fixed.

It's on GOG Galaxy, so yeah.

It's there now. 'Patch 1.64 to internal'. Timing is as per usual when a patch is released just before the weekend, but they really need to work on their bloody numbering scheme.

I see it, now. Thanks for info. Have good nite, buddy.
