Is now live. Expect your copy to autoupdate over the next 24 hours. Changes:

version 1.48
1) Performance: Major rewrite of tons of areas to reduce memory usage and squash lots of small memory leaks.
2) Bug fix: Tractor beam turrets are no longer drawn when a ship should appear cloaked.
3) Bug Fix: Limpet launchers and Plasmas are now fired from the correct position when placed in multiple-hardpoint slots.
4) Bug Fix: Fixed a few minor miscalculations that meant ship damage  looked (purely visually) like it was being repaired faster than it actually was, especially when cloaked.
5) Bug Fix: When you leave the ship design screen, any open module stat comparison windows are now closed.
6) Some playbalance tweaks
7) Bug Fix: Imperial fighters with tiny engine glows (also a nomad  fighter) now no longer get drawn when the parent ship is docked at a carrier.
