Original upstream Git repository was archived on March 3rd 2022 (https://github.com/CDrummond/cantata/commit/af04723c0ca7854df53562ed8226fd324d6a23cd#diff-b335630551682c19a781afebcf4d07bf978fb1f8ac04c6bf87428ed5106870f5R4). A maintained fork can be found at https://github.com/fenuks/cantata An open pull request to port the program to Qt6: https://github.com/fenuks/cantata/pull/1 While the current package (2.5.0-r1) still works fine for now, it would be nice to use the actively maintained fork instead. Thanks.
We are not going to switch to a random fork on GitHub. It should be an "official" fork, one that is blessed by upstream and with some future stability promise.
