Changelog for update 2.0.0 / GOG-3 (Windows) / GOG-4 (Linux) (added 28 April 2016):

Graphics:
- Added a number of new post processing graphics options, including Bloom, Godrays and Chromatic Aberration.
- Many many more improvements to shaders and and lighting to improve graphics quality
- The visual surface of planets is now actually rendered to match the biome tile grid from the planet overlay. City lights will automatically appear where buildings are!

AI:
- The AI has received numerous improvements to how it plays the game. Please report any bugs you find in its new behavior!
- You can now determine whether an AI is aggressive, passive and biased against humans separately from difficulty.
- You can now set the particular ways an AI cheats and how much it cheats at them

UI:
- The open tabs, quickbars, and camera location are now saved and restored when you load a game.
- Improved the planet requirement UI on the bottom left of the planet overlay.
- Added a Replace tool to the ship designer that replaces the subsystem you click on the design with the type of subsystem you have selected while keeping the same size.

Races & FTLs:
- Mechanoid population above 1 now provides 2 labor, but population above the maximum no longer provides any.
- Tweaked the income values of mechanoid planets over population so they don't jump up and down as much.
- Fling Beacons now cost FTL energy to construct and have a small FTL upkeep.
- Tweaked the cost and duration of opening slipstreams based on the size of the generator.

Notable Fixes:
- Fixed exploit for exporting labor more than once.
- Fixed exploit with Frugal trait where planets could be Level 2 without any tier 1 resources.

Has anyone tried the new Patch 2.0.2 yet?

Changelog for patch 2.0.2 / GOG-5 (Windows) / GOG-6 (Linux) (added 07 December 2016):

- Fix The First's Lab building consuming more Ore than it said in the description. It now correctly consumes 0.5 Ore/s (was 2 Ore/s).
- Fix Carpet Bomb description strings not being localizable.
- Increase cooldown of Skip Drive ability to 45 (was 20).
- Skip Drive and Ion Cannon artifacts equipped to ships now only grant 1 use per artifact, rather than a permanent ability.
- Buff Skip Drive and Ion Cannon subsystem stats so they require less space on the ship to be useful.
- Add bindable hotkeys for Open Planet Management, Open Support Management and Deploy Defense Reserve.
- Fix flagships with only Flak Batteries counting as civilian ships (Flak now counts towards DPS and strength).
- Fix Pulse Bolt range incorrectly scaling with ship blueprint size instead of actual ship physical radius.
- Choosing Sublight now replaces FTL Generation technologies on the research grid with Thrust improvements.
- Fix an issue that could grant bugged amounts of influence when failing to purchase designs with influence costs.
- Fix Museums and other unremovable buildings getting stuck in an incomplete state if canceled from the construction queue before completion.
- Fix AI fleets rarely getting stuck in an FTL charge-up loop.
- Fix Moon Bases adding their 2 max population immediately when they start construction, instead of when the construction finishes.
- Fix "Fill From" toggle on Outposts not correctly allowing fleets to automatically refill support ships from it.
- Fix Conflicts in race traits not correctly displaying as conflicting in the race customization menu.

just fyi that the current game patch on Gog version is 2.0.3 not 2.0.2
you need to get this update from the in game updater
