Winsparkle Versions Save

• Fixed release notes not shown if <sparkle:releaseNotesLink> is malformed and has whitespace around the URL (#177).

What's new:

• Added support for modern Edge/WebView2 browser for release notes.
• Added win_sparkle_set_update_dismissed_callback() and win_sparkle_set_update_postponed_callback().
• Added partiaul support for <sparkle:criticalUpdate> tag.
• Links in release notes now open in user's default browser as they should.
• Added support for Visual Studio 2019 and 2022.
• Added official NuGet package.
• Added support for ARM64 architecture.

⚠️ IMPORTANT: This version drops official support for Windows XP. It may still be possible to target it with vs*_xp toolsets, but would probably require at least disabling WebView2. Prebuilt binaries and NuGet package don't support XP. If you still ship to XP, you need to either build WinSparkle yourself or use v0.7.0.

• Added support for providing custom HTTP headers when fetch appcast feeds.
• Added support for overriding WinSparkle config functions.
• Reduced size of WinSparkle.dll.

This version adds support for validating DSA signatures, implemented by @Youw (huge thanks!).

Signatures are compatible with Sparkle and you can use either its tools or scripts in the bin directory for signing. Public key is set with win_sparkle_set_dsa_pub_pem() or in the DSAPub resource; please refer to the documentation and/or examples for details.
