There is a list of updates and new features for SO Main when the new round begins.
Some of the features like Alien Queen spawns are very interesting

- Alien Commanders can drop up to 5 items of the valuable type instead of only one
- hidden aliens power is compatible with player power now and there will no longer be aliens with too low or too high power in the hidden alien encounter
- the chance for Alien Commander after clearing hidden alien spawn has gone up considerably
- an Alien Queen can spawn after an Alien Commander is killed in the hidden alien encounters. The Queen can drop the most valuable items.
- the Alien Queen from the Incursion also drops very valuable / useful items aside from the usual ones if defeated
- turn items credits value has been increased
- Gold accounts can now deactivate the text below the vote links that displays general exchange rate info and announcements
- the number of stars in the Galaxy has been increased to 20 per quadrant instead of 7, totaling 2000 stars in 100 quadrants. This will make for more diversity of missions / encounters and more hiding places for planets, bases, facilities in the systems.
- a news entry is made if a player found 300 items or more.
- new players registering for the new round with 3000 or more turns passing since beginning of the round get a free 72 hours newbie nebula
Also there will be many new players coming in in the new round due to some advertising campaigns.
God Speed!
