This release is focused on improving the import module and implementing the recently introduced filtering approach based on counting reoccurrences of peaks in MS-scans and MS/MS-scans conceptually following Schuhmann et al. [1]. All other general functionalities of the former releases should not be affected [2-5]. Further changes were made for better documentation and simpler user guidance. Some experimental and/or unused options were deactivated (grouping samples, heuristic hierarchical alignment, dta/csv import). Details are available in the official release notes.
