Changelog: http://support.saleae.com/hc/en-us/articles/210245593-Saleae-Logic-Beta-Software-Changelog (Yes, the changelog title contains the word 'beta', but as of version 1.2.9 the beta branding is removed from the software as the beta branch was merged to master.) This software update is required for newer logic analysers (e.g. Logic Pro 8). (The original Logic is still supported, although it's difficult to find info about it on their website.) v1.2.9 grew new dependencies: libxcb, zlib, pciutils, xkeyboardconfig. The LD_PRELOAD library hack, used to divert writes from $out/Settings/settings.xml to $HOME/.saleae-logic-settings.xml, has been updated. The new software writes more paths ($out/{Settings,Errors,Databases,Calibration}) and uses a few extra library calls to access those paths (open,openat,stat,access,unlink,...). So instead of single file redirect, the library now redirects accesses to all those directories, mirrored in $HOME/.saleae-logic/. (Existing $HOME/.saleae-logic-settings.xml files will be automatically migrated to $HOME/.saleae-logic/Settings/settings.xml.)
