Significant changes:

  anytime through the Options dialog. (Bug #254 )
• Multiple Mutant and Renegade factions are now spawned in the galaxies,
  instead of having one faction starting on multiple planets.
• Mutant and Renegade now research technologies, and use pacts. Mutant
  only pacts with other Mutant factions, but Renegade now works as good
  trade partner to players. Starting level of technologies has been lowered
  to make early gameplay more balanced.

  FTL speed is not needed.

• Ship repair amount is minimum of 1, to help small ships on low-repair
  facitilities.
• Renegade and Mutant now benefits from STL engines.

  prototype technologies to proper TL1.

  ships.

• Flak defenses of Mutant structures has been transformed, now it follows
  traditional pattern where all sizes have same amount of hardpoints.
• Building structure over existing one will result in partial reuse of value
  i.e. structure will spawn with higher HP amount, depending on value of
  replaced one.
• Minimal growth of planet population has been increased from 20 to 100.

Fixes:

• Fixed table sorting.
• ETA of fleet command is now calculated properly during composition.
• Various fleet / redirect widgets now center properly.

  dialogs.

  with only 10 % of max HP. Structures are not changed, only starts up
  "damaged", instead of being build in perfect condition.
• Structures repair time is dependent on their CP costs, with the most
  expansive buildings being up to three times slower to repair than basic ones.
• Structures when not provided with enough pop/en will now deteriorate into
  sustainable state.
• Every planet has base CP production of 5
• TL-based population is now 100 * TL of player per slot, regardless building
  on the slot.

  line with the rest).
• Rebel players now accept economic pacts
• Limited scan power of a system to 150 (some top scanners max it out)
• Introduced primitive (ship) technologies, so players have more options how to
  play start of the game. Primitive technologies are similar to their normal
  counterparts, but are not upgradable, and are heavier, making ship options
  more diverse, but more defensive by nature.

• Galaxy booking is now much more stable (no longer handled by separate
  service)
• Booking dialog changed to be more user friendly.
• New galaxy sizes available.
• Construction dialog (ship design) has been updated to be easier to use.

  It will now build ships based on demand, attack more systems than just the
  closest one, and it will attack with different sizes of fleets.
• Minefields polish

  up to three minefields (in case of advanced Cyborg player) active in one
  system at the time. State of Mine Field Control structure influcences growth
