(expected deployment: May 6-10)

New Cerberus ship: Storm (RS9+, equipped with Dart Barrage)

Miners level 2 and over can be programmed to mine only on from specific sectors (Yellow Star only)
Miner can now be upgraded to level 6
Load All/Unload All buttons on the Shipments dialog (Yellow Star only)

Combat updates 5 times a second (30 times per hour in White Stars), up from 1 times a second/6 times per hour. Damage per second values are otherwise unchanged.
All weapon damage rates are now multiples of 5. Barrage DPS values were slightly tweaked up or down on various levels accordingly.
All combat is now properly affected by the Time Warp module

Mass Battery: DPS increased on level 2+ (does not affect Cerberus Interceptor)
Genesis: Fixed issue where genesis may not work if used on a White Star planet sector. Asteroids created with Genesis show up faded in the Time Machine and cannot be used as move targets for Time Machine scheduled commands.
Dart: Damage applied now properly affected by Unity on the firing ship, and by Fortify on the target ship.
Cargo Bay Extension: Capacity and Hydrogen use increased on levels 9 and 10, new level 11 available
Time Warp: Now properly affects firing rates for all weapons. Overlapping time warps do not stack visually, the highest level time warp draws above lower levels.

Joining a Corporation from an invite will no longer fail if the player doesn't meet the Corporation's minimum influence setting
Every player can opt in to receive notifications when a private Red Star search at a specific level starts, or when a message to all Corporation members is sent out (notifications on Steam only show while the game is running, connect your game with a mobile device to receive push notifications)

20vs20 slot removed
Each Corporation can now run two White Stars simultaneously
Available hydrogen increased on all star systems, especially 15v15
New reward levels system - fill the reward bar with mining, combat and relic activity to maximize rewards (the rewards bar will not appear on stars that started before the update and those stars will give out old rewards).

Ongoing White Stars dialog (will show ongoing White Stars, except for stars where one or both participating Corporations have disabled public broadcasting)
Time Machine: Future commands are scheduled on the current tick, instead of the next one. Scheduling a command less than 4 minutes into the future will no longer work.
