Dear Developers,
The band structures produced for the versions up to November 10, 2023 are fairly matches with the reported literature while after introducing "Abcof refactoring" on November 12 in development package, the band structures greatly changes (not meaningful). I am attaching a sample input file for your attention. The band structures with the development package until November 10 are insulators while just after that are metals for the sample Bi2Se3, which is a well known topological insulator. I have checked for other systems too but the issue is same.
