Note this upgrade comes in two flavours, one for PowerPC, one for the Universal Binary release.
Please check which version of Oolite you are using before proceeding by using Finder's Get Info on Oolite.app - if it says Kind: Application (PowerPC) use the PowerPC version, if it is Kind: Application (Universal) use the Universal Binary version.
FOR PowerPC VERSION (Standard Release Version)

FOR UNIVERSAL BINARY VERSION





The menu option About Oolite should also now show the version number as 1.64
Note that this will not update Oolite's version number in the Finder 'Get Info' box until the Finder is relaunched.
Main Changes for Version 1.64 (all versions)
• New equipment: EQ_HEAT_SHIELD, External heat shielding to make sun-skimming easier; EQ_TARGET_MEMORY, allows the shipcomp to store/recall up to 16 targets.
• Equipment availability system augmented, see equipment.plist for details.
• Improved implementation of radiation damage (very slightly less deadly, applies to NPC ships too).
• Implemented scanner un-zoom (press shift-Z).
• Allow selection of coincident target systems on the chart screens (click just above or below the system).
• Implemented control for ambient light level in planetinfo.plist (<key>ambient_level</key><real>1.0</real>).
• Implemented <key>isCarrier</key><true/>|<false/> in shipdata.plist entries.
• Implemented <key>rotaing</key><true/>|<false/> in shipdata.plist entries for stations.
• Implemented better handling of over-complicated models.
• More improemnts to sound code (thanks Ahruman).
• Fixed image handling problem (fixes Lave.oxp's moon bug).
• Fixed collision/scooping problems (fixes 'ghost escape pod' bug).
• Fixed text input problems (fixes 'Commander name change' bug, thanks Winston).
• Improvements to missile code: in shipdata.plist <key>missile_role</key> to select missiles fired by the ship, thargons going uncontrolled now properly shuck their target locks.
• Optimised lighting routines and aded more respect for the 'Reduced Detail' mode.
• Switched to GUSTO (Grand Unified Source Tree for Oolite) for future development.
• Many other minor bugfixes and glitch eliminations.
Version 1.63
• Bugfix to using zoom key in other chart screens.
• Laser vs. Ship collision detection now performed using octrees (more accurate.)
• Bug where default volume setting was 'Mute' fixed.
• All ship default console graphics are now drawn rather than taken from images.
• Hyperspace destination selected is now stored in the save game.
• ECM hardened missiles are no longer completely ECM proof (only 90% so.)
• Invincible Thargoid bug fixed.
• More aggressive data caching at start-up.
• Oolite 'strict' implements a non-zero forward velocity when speed is zero (like og. Elite.)
• 'addShipsWithinRadius:' 'consoleMessage3s:' 'consoleMessage6s:' methods implemented for scripting.
• Custom cargopods may be 'pre-filled' in their shipdata.plist entries.
• Player ship's model now drawn, permitting views of its external parts!
• Minor glitches fixed.
• Fuel scoop status indicator added to main display.
• Scooping flotsam now uses 'scoop_position' to determine where scooped items disappear into the ship.
• Major memory-use problems in AI addressed.
• Collision finding majorly overhauled to (crudely) partition space before tracking collisions - a big optimisation.
Note this patch can only upgrade Mac OS X Oolite v1.62 or later to the current version.
