MAJOR FEATURES & CHANGES
============================
Change 3795481 by Nick.Shin
HTML5 - disable SupportsScreenPercentage() - render the full screen
otherwise, this is causing HTML5 screen to only render a portion of the screen and in black...
- there may be another function is that not getting fired off "to render the screen" properly
- this may be due to IsMobileHDR checks that are not fully accounted for the HTML5 platform
#jira UE-52640 HTML5 only renders a black rectangle in the browser when launched
Change 3807007 by Nick.Shin
HTML5 - remove webgl1 only precompile guards (UE4_HTML5_TARGET_WEBGL2)
toolchain can "fallback" to webgl1 -- webgl2 functions in UE4 code are "if checked"/configured/setup at start up
#jira UE-51267 WebGL1 fails to compile
Change 3822593 by Nick.Shin
#jira UE-27141 Remove all #if PLATFORM_HTML5 from high level code

Change 3835867 by Nick.Shin
HTML5 - code cleanup
origial work was for: UE-27141 (Remove all #if PLATFORM_HTML5 from high level code)
this exposed an issue that i totally forgot about (.../Engine/Source/Developer/... only does builds tools -- which does not make use of PLATFORM_XXX preprocessor)
tested with HTML5 builds with QAGame project :: TM-ShaderModels map
#jira UE-53524 UE4Editor Static Analysis Win64 (MSVC) - 1 repeat warning
Change 3839967 by Mi.Wang

UE-54139 Possible crash with new virtual keyboard on Android if suggestions not disabled
#4.19
#Android
#jira UE-54139
S8 on 7.0 is not hiding suggestions and disabling predictive input. There are cases with this that can cause a crash.
Fix: On text change, downgrade to simple suggestions all the easy correction spans that are not a spell check span (remove android.text.style.SuggestionSpan.FLAG_EASY_CORRECT flags)
Change 3844210 by Nick.Shin
HTML5 - filter out "windows/super" keys - these are not used in UE4
- but, keycode are not the expected "91 or 92" values, SDL keys are "227 & 231" instead...
#jira UE-54056 HTML5 crashes inside browser upon pressing windows key
Change 3844874 by Nick.Shin
HTML5 - detect "SyntaxError: " and do a forced reload
- an actual syntax error would be caught during compile time
- this is usually error condition is usually seen when browser is running "old/partial" cached data and it's fairly safe to just reload the page
#jira UE-54017 QAGame fails to launch properly on HTML5 Firefox 64 bit
Change 3846695 by Nick.Shin
#jira UE-53524 UE4Editor Static Analysis Win64 (MSVC) - 1 repeat warning
Change 3847309 by Nick.Shin
HTML5 - (not to) show virtual joystick
- virtual joysticks are not shown by default-- and the mouse not captured
- this now behaves like the win64 client version
#jira UE-33854 Virtual Joysticks In HTML5 if Mobile/Tablet Project is chosen
Change 3847310 by Nick.Shin
HTML5 - set controller axis and button max value in code instead of relying on emscripten_get_gamepad_status()
- seems emscripten might be uninitialized by the time controlers are used...
#jira UE-28513 - Using a controller in HTML5 causes error
Change 3850606 by Nick.Shin
HTML5 - more static warning fix ups
#jira UE-53524 UE4Editor Static Analysis Win64 (MSVC) - 1 repeat warning
Change 3850624 by Nick.Shin

note: using following jira to track progress:
#jira UE-47066 Packaged HTML 5 Map Prompts for Firefox Update in Chrome
Change 3855610 by Sorin.Gradinaru
UE-49173 Progress bar causes black screen on iOS
#iOS
#4.20
#jira UE-49173
The bug occurs on iOS with Metal, when the last Slate element to be draw in the scene is a ScrollBar with progress between 0 and 1.
As a workaround, adding another widget (eg. button, image) in the Blueprint solves the problem.
The bug can be reproduced by adding OutDrawElements.PushClip & OutDrawElements.PopClip in any SWidget::OnPaint.
The solution is to disable the scissor
RHICmdList.SetScissorRect(false, 0, 0, 0, 0);
in FSlateRHIRenderingPolicy::DrawElements after the batch rendering
Change 3855652 by Sorin.Gradinaru
iOS 3D browser
UE-53248 Web Browser on a Widget Component is 2D when launching on to iOS
#jira UE-53248
#iOS
#4.20
Uses the same WebTexture from the WebBrowser plugin as the Android version.
+ Code contributed by Juan.Belon from Alea S.r.l at https://udn.unrealengine.com/questions/390166/3d-world-space-widget-is-being-rendered-in-screen.html

Change 3889081 by Sorin.Gradinaru
UE-54490 Android Startup Movie audio still playing when app paused, and after app resumed the movie is blackscreen until engine ticked.
#Android
#4.20
#jira UE-54490
Call ForceCompletion for the intial movie player on onPause.
Call App Restart on Resume.
Programmatically restarting an Android application basically consists in killing the current app, then using the launch intent as parameter for startActivity.
This can be done only in onResume , which means that the movie player still has to be manually paused/stopped in onPause.
I╞ve tried to kill the activity on onPause, tested on several devices, with various problems: the app doesn╞t restart anymore (onResume is not called) or the app is automatically sent to background (seems to be crashing when using the multitasking soft key).

UE-57107 Attempting to load a streamed media source causes the app to become unresponsive when device is not connected to internet
#jira UE-57107
#Android
#4.20
The ANR is because the android.media.MediaExtractor.setDataSource(UrlPath) calls an underlying api which retries the download (10-30 times).
Additional issue (all platforms): the MediaFrameworkTest/StreamSource_Infiltrator souce seems to have been removed (no longer at https://docs.unrealengine.com/latest/attachments/Engine/MediaFramework/HowTo/StreamMediaSource/Infiltrator%20Demo.mp4). According to the docs (https://docs.unrealengine.com/en-US/Engine/MediaFramework/HowTo/StreamMediaSource) the new location of the Sample Video is at https://dnnrz1gqa.blob.core.windows.net/portals/attachments/Engine/MediaFramework/HowTo/StreamMediaSource/Infiltrator%20Demo.mp4?sr=b&si=DNNFileManagerPolicy&sig=F%2BBpnYueeQTUTSW0nCRSrXEfr35LIawe7C3MQoe2%2FPI%3D

UE-57120 Lighting needs to be rebuilt error appears on Camera test app on Nexus 9 and Note 4.
#jira UE-57120
#Android
#4.20
Level lightings rebuilt and QA-Media_Camera_BuiltData.uasset added.
The message appeared (rarely and only on certain devices) because the engine tries to load the pre-computed lightmap data on the render thread, then to add it to the scene on the game thread (in FPrecomputedVolumetricLightmap::AddToScene).
Most of the times there is a desync and the data is not yet loaded when the lightmap is validated (in FScene::AddPrecomputedVolumetricLightmap).
Change 4013034 by Sorin.Gradinaru
UE-55427 iOS application crashes when suspending and resuming the startup movie in rapid succession
#jira UE-55427
#iOS
#4.20
Caused by ToggleSuspend waiting for FDefaultGameMoviePlayer::WaitForMovieToFinish()
Renamed InitialMovie to StartupMovie, including the methods related to the Android platform.
Change 4015449 by Sorin.Gradinaru
UE-38306 "Running xxx on yyy" panel Cancel button should terminate app
#jira UE-38306
#Android
#4.10
Run on device: Pressing Cancel on the "Running..." message should stop the application, if running
Cancel Android builds using "adb shell am force-stop <bundle_id> <device_id>"
Note: Using a new AutomationTool command (re-starting the Automation tool after canceling the BuildCookRun task chain) is too slow - takes 3-10 sec depending on the PC configuration.
AutomationTool is used now only to correctly retrieve the bundle id for each Android device. This is done inside the BuildCookRun command when the application is deployed on the device(s). Cannot simply use the current project's properties to retrieve the bundle id, because when using Launch-> Device Launcher, the user can choose to cook&deploy a different project/texture format, also the user can create & use a profile with multiple devices / with different texture formats.

UE-57876 Location accuracy is ignored by ULocationServicesIOSImpl
#jira UE-57876
#iOS
#4.30
In ULocationServicesIOSImpl::InitLocationServices(ELocationAccuracy Accuracy, float UpdateFrequency, float MinDistance) the first param must be converted to CLLocationAccuracy and used as the first param of LocationDelegateinitLocationServices, rather than using the hardcoded kCLLocationAccuracyHundredMeters.
Also fixed a compilation error (!) when enabling The Location Services plugin on iOS

UEMOB-436 Support "All Android" Launch On and Project Launcher options
The main change is in the DeviceProxy class.
A new type ("All devices" proxy) was added, and the proxy now holds a list of physical device IDs for every variant (texture format), instead of a single device ID.
The "All devices" proxy is updated automatically by the device discovery thread.
The change was necessary because the list in the Project Launcher is using the device proxy list.
