First of all, I apologize for the delay of 0.2.1 - this build had some issues in the beta branch and I kept it in beta a bit longer than usual. If you are on the beta branch and are affected by the issue, please see this thread for details.
This means 0.3.0 will be slightly delayed as well. 0.3.0 will bring a wonder cost balance (more streamline build time / cost), new great people, and a reworked market and warehouse. Several player trade enhancements. You can see the roadmap here
0.2.1
Bugfix: Fix a bug where transport preference / max transport distance are carried over after rebirth before the relevant tech is unlocked
Bugfix: Always show transport preference for Warehouse/Caravansary
Bugfix: Fix a bug where Hagia Sophia, Summer Palace and Mogao Caves causes double counting of happiness from Shrines
Bugfix: Fix a bug where sometimes building have extra resources after construction / upgrade
Bugfix: Fix a bug where Statistics does not include market output
Bugfix: Fix a bug where happiness fractions are not correctly rounded
