v2.4.0-pre1

Pre-release for testing -- not a public build.

Do not install unless you're prepared for bugs and will report them on GitHub. YWC's in-app auto-updater ignores pre-releases, so existing users will not be prompted to upgrade to this build.

Please send feedback via GitHub Issues (or mm5agm@outlook.com). Mention the v2.4.0-pre1 tag when reporting.
