Jet Isp halved due to increased fuel quantity and lower drag. * Jet thrusts rebalanced for new drag (thrusts lowered, BJE curves altered). * KR-2L description updated, mass to 9t, SL Isp to 255. * Rebalance of SRB for the new drag changes. * Further decrease in LV-N heat production. * Added Hsp (resource thermal mass value) to Ore resource. * Lowered skin thickness slightly globally, made magic number sane (part.skinMassPerArea is now in kg/m^2). * Fixed issue with radiation (no longer have to use dirty hack to prevent parts blowing up). * Fix some small issues in conduction (better clamping), sped it up slightly. * Add conduction between parts' skins (as well as between the internals of parts, between a part's internals and its skin, and between the exposed and unexposed skin of a part, all of which were already in.) * Remove thermal mass as a factor in conduction rate: what matters is area. * Better compute various vessel values This should lower phantom orbit changing and wobble! * Sped up Flight Integrator slightly by minimizing repeated loops through parts. * Skin temperature variables are controllable on per-part basis. * Parachute module updated to use the new convection code. Changed burn/rip numbers for drogue chutes. * Added conduction-changer module to Mk1 and Mk1-2 pods (necessary to not kill chutes), buffed heat shields for new heat loads. That corrects so steep reentries are in fact deadlier than shallow ones. * Added a factor to simulate the switch from laminar to turbulent flow (in layman's terms, if you're going too fast too low, you get a massive boost to heating). * Clamped convection correctly so you will never pass external temperature. * Broke radiation into two parts, you get the regular background temp on your face not exposed to reentry flux, and the very high reentry one for the area that is. * Flight integrator: allow setting of newtonian density exponent (default 0.5) and use density or density^exponent whichever is greater. * Calculation of exposed area for convection fixed, spaceplanes no longer get as extreme heat. * Wing curves modified to lower change in drag based on deflection. * Drag curves modified to lower transonic hump. * Newtonian convection kept pace with hypersonic convection. * Convection velocity exponent raised to 3.3 to increase reentry heat, as well as convection factor. * With lowered drag for sharply-tapered cubes, wing lift and wing drag lowered to match. * Added curve to control drag coefficient exponent to DCL and Physics.cs * Radiative outflux and influx is tracked separately for exposed and unexposed areas of skin (since the shock temperature is much higher than ambient temperature). * When not in an atmosphere, only one skin temperature is tracked the two temperatures are unified on atmosphere exit. * When in an atmosphere, there is a divide between the exposed (to convection) and unexposed skin temperatures. * Solar panel efficiency is now calculated based on skin temperature. * Part internal and skin temperature also conduct between each other. * Part internal temperature is increased by modules that generate heat and is used for part-part conduction. * Skin temperature is the temperature used for radiation and convection, as well as engine exhaust damage. * Parts now have separate internal temperature and skin temperatures. * 1.0.3 features a revised thermal mechanic to better balance heating/cooling between pods and spaceplanes. * Fixed an issue where moving the camera using a 3D mouse would break drag-and-dropping of parts in the editors. * Fixed unfortunate typo in the Docking Tutorial. * Fix for horizontalSrfSpd being incorrectly calculated. * Fixed KSPUtil.PrintLatitude/Longitude giving wrong result for small negative values. (fixes memory leak with temperature overlay) * Disabled flashing highlighter in temperature gauges. * Made part's internal highlighter much more efficient. * Fixed a bug where using the reset button with an Asteroid loaded would break the Mun tutorial. * Added five new Radiator parts, three of which are deployable.
