I'm pleased to announce that the Technology Open Beta that we first talked about in Stellaris Dev Diary #325 is now available for your feedback.
[quote author=Eladrin]
Stellaris has undergone a significant amount of power creep over the years, and the speed at which we're able to burn through the entire technology tree is much higher than is healthy for the game. Due to the large number of stacking research speed modifiers, repeatable technologies are reached far too early in the game. Another power creep issue mentioned by many players, it's also become trivial to stack large numbers of ship build cost and ship upkeep reduction modifiers.

The Holiday Open Beta will be a feature branch that contains the following changes, which may or may not go into 3.11 (or 3.12, or any release at all for that matter). Similar to how we handled Industrial Districts several years ago, we're intentionally keeping these separated from core 3.11 development, isolating this in a parallel track.[/quote]

The dev diary linked above contains more details regarding the intents behind some of the changes. While some changes planned for 3.11 Eridanus have snuck into this release (like some improvements to Galactic Doorstep), the overall technology rebalance is considered experimental and may or may not end up being released. It is likely to undergo some changes if it does go live.

We have created this feedback form to collect your impressions on both the partial tech rebalance and the military and economic changes that are present on the branch.

[h3]TECHNOLOGY OPEN BETA RELEASE NOTES[/h3]
Features

• Replaced basic research technologies such as Quantum Theory with Breakthrough Technologies. Breakthrough Technologies will only appear once you have researched enough techs of your current tier and are required to research to reach the next tier.
  
• Breakthrough Technologies become easier to research based on the number of other empires you have low Tech intel on that have already researched them.
  
• Enigmatic Engineering blocks your Breakthrough Technologies from spreading.
  
• Events that give progress towards random technologies can grant progress towards Breakthrough Technologies, but will not give as much as they would a regular technology.
  

• Technology and Tradition costs are now distinct sliders in galaxy setup.
  
• Added notification message when new pop settles in zeya (Gaia planet in azilash)
  

• Adjustments made to the Galactic Doorstep origin:
  
  
  
  • Added Gateway Cost and Megastructure Build Speed modifiers to the Galactic Doorstep origin.
    
  • Galactic Doorstep event chain now directly rewards the Gateway Activation technology and gives far more progress on the Gateway Construction technology
    
  
  
• Increased the effects of Empire Size on Technology to match its effect on Traditions.
  
• Rebalanced research speed modifiers. Most sources of Research Speed now have a corresponding increase in Researcher job upkeep
  
• Removed or adjusted many sources of Ship Cost and Upkeep reductions from the game.
  
• Military Buildup Agenda now improves ship build speed and reduces claim costs. (It still reduces War Exhaustion on completion.)
  
• Naval Procurement Officer councilor now improves ship build speed.
  
• Crusader Spirit civic now improves ship build speed.
  
• Psionic Supremacy (Eater of Worlds) finisher no longer reduces ship build costs.
  
• Vyctor's Improved Fleet Logistics trait now reduces ship build costs by 10% instead of 20%.
  
• Progress Oriented modifier no longer reduces ship build costs.
  
• Match tradition in the Enmity tree bonus to ship build costs reduced to 5% instead of 10%.
  
• Master Shipwrights tradition in the Supremacy tree no longer reduces ship build costs.
  
• Military Pioneer trait now reduces starbase upgrade costs instead of ship build costs.
  
• Shipwright trait no longer reduces ship build costs.
  
• Reduced penalty the Irenic trait applies to ship build costs.
  
• Sanctum of the Eater ship upkeep reduction reduced from 10% to 5%.
  
• Mark of the Instrument ship component no longer reduces ship upkeep.
  
• Grand Fleet ambition now increases power projection instead of reducing ship upkeep.
  
• Fleet Supremacy edict no longer reduces ship upkeep.
  
• Corporate Crusader Spirit now reduces ship upkeep by 5% instead of 10%.
  
• Bulwark ship upkeep reductions reduced by 50%.
  
• Logistic Understanding, Armada Logistician, and Gunboat Diplomat traits now reduces ship upkeep while docked.
  
• Increased technology costs, especially those of higher tier technologies.
  
• The Technology curve has been changed from 1000 2^n to 500 (2^n + 3^n), making the difference between an early and late-game tech more distinct.
  
• Reduced output of researcher jobs
  
• Researchers and their gestalt equivalents now produce 3 of each research instead of 4
  
• Head Researchers now produce 4 of each research instead of 6
  
• The effectiveness of Ministry of Science has been halved
  
• Astral Researchers now produce 5 physics and 1 of each other research instead of 5 physics and 2 of the other researches.
  
• Knights of the Toxic God balancing:
  
  
  
  • Slightly reduced the research output for Knight and Lord Commander jobs
    
  • Refactored how the output scaling for Knights from Squires functions, these now behave as normal additive modifiers instead of multiplicative modifiers
    
  • Knights now correctly inherit production modifiers from researchers and administrators
    
  • Slightly reduced the unity and research output for Knight and Lord Commander jobs
    
  • Knight output modifiers now only apply to resources, like other job output modifiers
    
  • The Fortress Habitat Designation for Knights no longer provides +1 Defensive Army per pop on the habitat, instead each Squire job provides +1 Defensive Army
    
  • Squires now increase the resource output of Knights by 2.5% not 2% per Squire.

• Reworked and rebalanced the Erudite, Cyborg, Synthetic, Psionic, Chosen One, and Chosen of X traits to include new leader assignments.
  

• Repairing The Black Crown should no longer fire generic gateway repaired events.
  

• Added `last_resolution_category_changed` trigger
