Bug fixes when WebGL build. You can download WebGL.zip and test BaseProfiles demo. 

• To start WebGL test you need use IIS or Apache web server. I'm using IIS. Here is some instruction of how to deploy demo to web server.
• Open IIS panel, see how to install it on Windows 10, and on the left side you will see the sites list. 
• To create a new site ypu need to right click on Sites list folder and then Add new site.

After you created new site got to Mime Types section and then click Add link at the right side

You will see Add new MIME type dialog

Input .unityweb and application/unityweb as shown on the screen below

Then go to  C:\Windows\System32\drivers\etc and open hosts file with your notepad or note++ with admin rights.

Insert new local url. If your site url is webgl.loc just insert this url in hosts file as shown on the screen below.

• Save hosts file and then go to your site directory. In my case this directory is located in D:\WWW\WebGL
• Paste all files and folder from WebGL -> WebGL.zip to your site folder
• Start master server with Start Server.bat file from MasterServer.zip
• Try to input your web site local URL to browser starting with http://webgl.loc

If you have done all correctly you will see this window

If you have any question feel free to ask!
