Hi Ondřej, You have recently released lm-sensors 3.5.0 with a new soname for libsensors: -LIBMAINVER := 4 -LIBMINORVER := 4.0 +LIBMAINVER := 5 +LIBMINORVER := 0.0 -#define SENSORS_API_VERSION 0x440 +#define SENSORS_API_VERSION 0x500 This is declaring the new library as incompatible with the previous version, meaning that distributions will have to build and ship both libsensors4 and libsensors5 for a long time until all applications have been updated and rebuilt to link with the new library. This is a significant effort for the whole community and should only be done when necessary. In this specific case, I can't see what warranted such a change of major library version change. From lm-sensors/doc/developers/release_checklist: Remember: update main number when interface changes, minor if new functionality is added, and patch if only bugs are fixed. In this case I can only see new functionality added, there is no interface change. Therefore the correct value for SENSORS_API_VERSION was 0x450, not 0x500. This would avoid the parallel maintenance and installation of 2 versions of the library for several years to come. Would you consider quickly releasing lm-sensors 3.5.1 with the proper library version number, to save all that work to all application authors/maintainers and distribution package maintainers?
