Read this first: http://www.tasharen.com/forum/index.php?topic=6 ------------------ FreeType Library ------------------ NGUI version 3.5.2 onwards includes the pre-compiled C++ FreeType library, which is an open source project (http://freetype.org/) FreeType license: http://git.savannah.gnu.org/cgit/freetype/freetype2.git/tree/docs/FTL.TXT This library is used only if you choose the "Generate Bitmap" font option in the Font Maker, and it will not be included in the build of your game. It's only used in the editor. ----------------- Version History ----------------- 3.5.7 - NEW: Added OnDragOver/OnDragOut to the Event Trigger. - FIX: Event delegate compilation on platforms that don't support reflection. - FIX: The example tooltip should no longer go off-screen. - FIX: Exposed UISprite's 'flip' option to scripting. - FIX: Context menu 'Attach' options should now work with multiple objects selected. - FIX: 'Attach' menu options should now all be undo-able via CTRL+Z. - FIX: Exposed UIButton.state for those that may need it for any reason. - FIX: UICamera's raycasts can now be clipped by nested panels. - FIX: MakePixelPerfect should not change the width if the label is set to "resize height". - FIX: Made UIButton.isEnabled work with a 2D collider. - FIX: Unity 4.2 compatibility tweaks. - FIX: Clip softness can now be 0. 3.5.6 - NEW: Added basic built-in data binding support (PropertyBinding script). - NEW: All delegates now support any number of parameters that you can set in inspector. - NEW: You can now nest scroll views (scroll views within scroll views).
