- Remove |accept_lang| parameter from CefJSDialogHandler::OnJSDialog and CefFormatUrlForSecurityDisplay (see https://crbug.com/336973#c36). - Remove remaining NPAPI-related code including functions from cef_web_plugin.h (see https://crbug.com/493212#c55). - Mac: 10.7+ deployment target is now required for client applications. - Mac: Remove CefBrowserHost::SetWindowVisibility (issue #1375). No replacement is required for windowed rendering. Use WasHidden for off-screen rendering. - Windows: Visual Studio 2015 Update 2 is now required when building CEF/Chromium.
