Sparkle 1.27.1-rc.2

• Use px instead of pt when specifying font size to fix default font size in WebView from #1962 (regressed in 1.25.0 with WKWebView adoption) (Daniel Jalkut)
• Fix to prevent Sparkle manipulating the host app's high level WebView defaults from #1961 (affecting only macOS versions before 10.11 in 1.x branch) (Daniel Jalkut)
• Add safer handling of applying binary delta files from #1990 (Zorg)
• Don't use current date unless necessary when scheduling next update to be more resilient against rapid polling from #1991 (Zorg)
• Prevent potential (unlikely) rapid update checks from sleep/wake events using a minimum monotonic delay from #2000 (Zorg)
• Whitelist about:srcdoc as a safe web URL from #1938, #2007 (Louis Pontoise, Zorg)
• Backport not hiding update window on deactivation from #2008 (Zorg)

If you use Sparkle's Delta Updates support, you must create new delta files using Sparkle 1.27.0 or later. Newly generated delta files will still be patchable from older versions of Sparkle however.
