This is the biggest patch since the early access launch: it took me hours to collect all the changes and I am sure I have missed a lot. Not only we get a new era (World Wars) with 16 new buildings, 6 new wonders, 7 new great people and lots of significant gameplay changes! Also the balancing of the game has been improved to make new eras feel more significant and make longer runs more viable. The permanent great people carry-over rule for Tribune rank up has been relaxed to make it more friendly for new players while helping keep bots/spammers/cheaters away and keep the game completely free for everyone. Also Devonin has written an extremely helpful new player guide. If you are new to the game, be sure to check it out! Here are the patch notes:

World Wars Great People

• Herodotus now boosts Paper Maker instead of Writer's Guild
• Shakespeare now boosts Writers Guild instead of Paper Maker
• John D. Rockefeller: +1 Production, Worker Capacity and Storage Multiplier for Oil Well + Stock Exchange
• Rudolf Diesel: +1 Production, Worker Capacity and Storage Multiplier for Oil Refinery + Locomotive Factory
• Pierre de Coubertin: +1 Production, Worker Capacity and Storage Multiplier for Publishing House + Stadium

Gameplay

• Buildings that produce science will continue to produce science even if its storage is full (if there's another output, the other output will not be produced)
• Each level of permanent Great People provides 5 workers in your Home Building
• The number of workers required for production has been changed to the sum of all resources consumed and produced after multipliers (except electrification). Resources that do not take storage (e.g. Science or Power) do not count
• All buildings that produce science get ~2.5x more science output
• Electricity has been reworked: now power plants will provide power to adjacent tiles. Certain buildings will require power to function and need to be built on top of a tile with power - they also extend the power grid to its adjacent tiles. Electrification is more efficient for buildings that require power.
• Offline time should now be more reliable. Thanks to all players providing logs and reports, I have located the main reason why sometimes offline production is missing. This usually happens when the initial connection to the server is timed out (either due to a network hiccup or Steam authentication API timeout). Eventually, when the connection is established, the game has already been running for a while and the server will refuse to grant offline time due to the mismatch. I have added a special handling of this case. If this happens, the whole offline time will be converted to warp in Petra (because offline production is no longer possible). You will get an in-game notification about this.

Balancing

• Increase the empire value of deposits that are discovered in later ages. This will trickle down to all the downstream resources
• Increase the empire value of resources that require more types of input to produce, see: https://discord.com/channels/631551126377857044/1218571470457016361/1218571470457016361
• Streamline wonder building cost: most wonders should see a reduction in building cost, with more in later ages. This means if you upgrade from 0.4.x, your empire value might decrease due to this, see: https://discord.com/channels/631551126377857044/1102225155830317136/1221426548423266434

• Museum: Music x2 + Painting x2 => Culture x1

• Magazine Publisher: Sports x2 + Book x10 => Magazine x1 + Science x400
• Parliament: Culture x2 + Philosophy x2 + Law x2 => Politics x1
• Parthenon: Two great people of Classical Age are born and you get 4 choices for each. Musician's Guilds and Painter's Guilds get +1 Production, Worker Capacity and Storage Multiplier and are exempt from -1 Happiness
