LightBulb Portable 新版更新日志：
- Added gamma polling option. When enabled, LightBulb will force-refresh gamma every few seconds to make sure it's in sync. In most cases, you should not need to enable it, but if you're experiencing issues then this option may help.
- Added an option to disable auto-updates. If you prefer not to have the latest version of LightBulb, you now have the option to do so.
- Fixed an issue where LightBulb didn't pick up new monitors if they were connected after it was launched.
- Fixed an issue where the time was shown using the invariant culture, instead of the current system's locale. Now the time format should reflect what's configured on the system.
- Fixed an issue where the application would work abnormally or crash when there was no full sunrise/sunset for that particular day.
- Minor UI improvements.
- LightBulb installer will now detect if the required .NET Core Runtime installation is missing and download and run the appropriate installer if so.
