libsgfc++ 2.0.1 contains changes (specifically: the use of std::filesystem::temp_directory_path()) which require the iOS SDK 13. This would require changing the deployment target from 9.0 to 13.0, i.e. dropping support for iOS 9-12.
However, according to the Wikipedia device support articles for iPhone, iPad and iPod the two iOS versions 13 and 14 do not drop support for any additional devices. This means we can change the deployment target directly to 15.0.
By changing the deployment target to 15.0 we drop support for the following devices:
iOS/iPadOS 9
iPhone models: iPhone 4S
iPad models: iPad Mini 1st generation, iPad 2 and iPad 3rd generation
iPod models: iPod Touch 5th generation
iOS/iPadOS 10
iPhone models: iPhone 5 and iPhone 5C
iPad models: iPad 4th generation
iPod models: None
iOS/iPadOS 11
None
iOS/iPadOS 12
iPhone models: iPhone 6, iPhone 6 Plus and iPhone 5S
iPad models: iPad Air 1st generation, iPad Mini 2 and iPad Mini 3
iPod models: iPod Touch 6th generation
iOS/iPadOS 13 + 14
None
Apple discontinued the newest of these devices in 2016/2017, so 6-7 years ago. Although the list is quite long, this also provides a chance for getting rid of old cruft in the code. The planned jump to a new major version is also a good point in the project development cycle to announce such a change.
