Known Issues
On Windows 7, system dialog (File Open/File save) and homescreen/project launcher window, the editor in the background doesn't redraw properly when the window is dragged around
Legacy Light Probes baked coefficients doesn't get upgraded to the new data format, probe coefficient data will be incorrect. New Light Probe Groups will behave correctly.

Changes
Editor: UI improvements to Standard shader emissive color/texture/intensity fields.
Shaders: Renamed UV1/UV2 in Standard shader detail UV selection to UV0/UV1.

Improvements
API Updater: Introduced UnityAPICompatibilityVersionAttribute to allow updater to avoid checking assemblies already updated to / compatible with current Unity API.
Check Plugin Inspector documentation for more info
Deferred Shading: Standard shader outputs occlusion texture into diffuse g-buffer alpha channel.
Documentation: Added documentation for "Optimizing Shader Load Time" and "WebGL Networking" plus lots of improvements and fixes in general
Editor: Fixed undoing changes to light probe group
GI: Exposed modelling tolerance to lightmap parameters. This parameter allows setting the maximum size gap to be ignored by GI calculations.
GI: Clamp AO distance to zero in UI. AO distance of zero means infinite length rays as it did in beast.
GI: Added a baked lightmap tag. This can be used to force instances into specific baked lightmaps.
Plugins: Added default settings for plugins located in:
Editor\x86
Editor\x86_64
WSA\SDK80
WSA\SDK81
WSA\PhoneSDK81
WSA\UniversalSDK81

Plugins: Only relevant Standalone plugin settings will be shown. For ex., OSX and Linux options won't be shown for native dll, because it cannot be used on those platforms
Plugins: Added warning box for native plugins in plugin inspector, once native plugin is loaded by scripts, it cannot be unloaded until Unity is restarted.
Profiler: Stop collecting GPU data when GPU Profiler chart is closed
Profiler: Stop collecting profiler's data on Player's side if recording is disabled
ReflectionProbes: Added QualitySettings.maxRealtimeReflectionBounces, this limits reflection bounces for realtime reflection probes.
ReflectionProbes: When baking Custom probe, game object's name will be appended to the filename
ReflectionProbes: When manually entering position values in the Transform inspector while in Box editing mode, the box will not move.
ReflectionProbes: You can now set bake resolution for default reflection, it can be found in Lightmapping window
TerrainCollider: Removed warning about TerranCollider no longer supports being a trigger from get_isTrigger
Timeline Profiler: Add proper detailed names to Physics Jobs and prefix the names with "PhysX".
Shaders: Added "keepalpha" surface shader directive to not force 1.0 to alpha channel for opaque objects.

Fixes
2D: Sprite Packer page list is now refreshed after packing.
2D: Sprite importer multiediting now works for packing tag, pixels per unit and extrude fields
2D: Sprite name can't be empty, or contain characters that are not supported in assets when created from Sprite Editor
2D: Hotkey for sprite Trim 'T' doesn't intervene with sprites naming anymore
API Updater: After being updated, some assemblies fails PEVerify with message "[MD]: An attempt was made to load a program with an incorrect format."
Editor: Animation Window Add Property button not hiding for new project
Editor: Fixed null exceptions from Animation Window when opening projects
Editor: Shadows working correctly when zoomed in animation preview window
Editor: Fix exception when clicking "Add Behaviour" button
Editor: Remove unsupported OSX menu items (Start Dictation & Special Characters)
Editor: Fixed wrong color for editor progress bar in dark skin
Editor: Fixed repaint issue on Win7 for windows under modal windows
Editor: Recently used projects list now has separate keyboard selection and mouse hover again (hover changing selection was making "enter to reopen" unpredictable)
Editor: Fix Windows repaint issues with windows behind modal windows on Win7
Editor: Fix that undoing when creating assets would cause the temporary asset state to not be cleared
Editor: Fix ctrl+click as context click for audio mixer groups
Editor: Don't show "Fix now" button for legacy cubemaps in shader UI, fixes crash.
Editor: Fixed emissive Standard materials getting same emission color when multi-edited.
Editor: Fixed semaphore issue on OSX
Editor: Reduce serialization depth limit warnings
Editor: Fix crash when executing a menu item from a static constructor
Editor: Remove spurious "Platform modules already initialized" messsage when upgrading projects
GI: Fix issue with too high intensity GI in the players.
GI: Fix issue with lightprobes when baked multiple time in non-continuous mode.
GI: Make sure GI has converged before issuing reflection probe jobs.
GI: Fix skybox appearing very dark in gamma rendering mode.
GI: Fix for creating lightmap data assets larger than 4GB.
GI: Fix spurious errors when converting area lights for GI.
Graphics: Fixed "Tiled GPU perf. warning" in editor resulting in poor performance.
Graphics: Texture2D.SetPixel and friends work with floating point texture formats (TextureFormat.RGBAFloat etc.) now.
Graphics: Floating point texture formats (TextureFormat.RGBAFloat etc.) work on D3D9 now.
Installers: Download Assistant on Mac doesn't ask for credentials again after downloading has completed
iOS: Fixed allocator assert when doing skinning
Linux: Trim device identifier
Metal: Fixed some shaders not compiling properly (if they change global variables from inside of the shader).
ParticleSystem: Fixed regression from Beta 17: Broke editor update of selected particle system.
Plugins: Unity will correctly load native plugins from script even if the letter case won't match like it was in 4.x, for ex., if you write DllImport("plugin"), but on disk it's Plugin.dll (with upper case).
Plugins: Fixed a rare crash when calling into native plugin from finalizer thread.
ReflectionProbes: When baking probes, Unity will no longer bake shadows from objects which are not marked as ReflectionProbeStatic
ReflectionProbes: Fixed a bug, where Unity would sometimes not rebake probes or default reflection, when material has a different cubemap setup.
Reflection Probes: Realtime probes more efficient on mobile GPUs (less framebuffer restores).
Scripting: Fix crash when calling DestroyImmediate in MonoBehaviour constructor
Serialization: Added ability to do automatic fix of invalid references to scripts in scene file (to valid registered scripts)
Serialization: Fixed windows Layout loading if script for previously opened custom window is absent
Shaders: Fixed legacy Diffuse Detail shader when in linear color space.
Shaders: Fixed "Maximum number of shader keywords" error in editor resulting in really bad build-time performance.
Shaders: Fixed Sprites/Diffuse shader not handling transparency properly.
Shaders: Fixed Standard shader using wrong texture scale/offset value.
Shaders: Fixed Standard shader wrongly falling back to VertexLit when lower shader LOD is set.
Shaders: Fixed exceeding maximum shader keywords sometimes resulting in crashes.
Windows: Windows 10 reports SystemInfo.operatingSystem string properly.
Windows Phone/Windows Store Apps: Gyroscope.gravity returns same values as other platforms. It used to be inverted before.
Windows Phone 8: Camera.ViewportToWorldPoint returns correct value in orthographic view.
Windows Store Apps: fix building Universal apps in batch mode

Устанавливаем программу UnitySetup64.exe (в конце установки снимаем галку, чтобы программа сразу не запустилась).
Запускаем от имени администратора Unity 4.x Pro Patch.exe из папки Crack .
Нажимаем на "Browse" и выбираем папку Editor по установленному пути (по умолчанию: C:\Program Files\Unity 5.0.0b18\Editor )
Либо можем сперва скопировать Unity 4.x Pro Patch.exe в папку Editor и уже оттуда запускать от имени администратора.
В центре из раскрывающегося списка выбираем Unity 5.0.0f1 (beta).
Нажимаем на "Patch".
Готово.

Графическая карта с поддержкой DirectX 9 (шейдерная модель 2.0).
Должна работать любая карта, выпущенная начиная с 2004 года.
Для использования функции Occlusion Culling требуется графический процессор с поддержкой Occlusion Query (некоторые графические процессоры Intel не поддерживают ее).
