Dear XDS users in the Phenix community, as reported by users, and confirmed in a larger-scale comparison by GlobalPhasing, the BUILT=20240723 of XDS Version 20240630 leads to problems for some datasets when compared with (the expired) XDS Version 20230630. (it may be better than the 20230630 version for other datasets!). An improved BUILT=20241002 of the 20240630 version is available (all platforms) from https://xds.mr.mpg.de/html_doc/downloading.html for non-commercial (academic) users (commercial users have their own arrangements). In my/our testing, it is at least as good as version 20230630, and often better. Please install and use this instead of BUILT=20240723. If you still find deficiencies, please contact me or Wolfgang Kabsch - but be prepared to share the raw data (confidentially, of course). To enable comparisons, the old XDS version 20230630 was re-released for Linux by Wolfgang Kabsch with expiration date 2025-Mar-31; the link to its XDS_old.tar.gz is at https://xds.mr.mpg.de/ . Best wishes, Kay
