We’re aware Github has (unfortunately) been blocking access to some countries, which is restricting people’s access to Quelea. At present we’re unsure as to if this will be permanent or not, but for now we’ve just uploaded the releases separately to the Quelea server:
https://quelea.org/mirror/quelea-2019.1-crossplatform-install.jar
https://quelea.org/mirror/quelea-2019.1-mac.zip
https://quelea.org/mirror/quelea-2019.1-x64-windows-install.exe
Hopefully if the situation continues, we’ll look to get a more permanent mirror in place.
