I think it would be dangerous to assume this holds true for other packages too. In the semantic versioning world as npm packages expectexd to behave - and nodejs itself certainly does! - a change in the major version means a breaking change of some kind. > > Regards > Stefan > -- > _______________________________________________ > yocto mailing list > yocto@yoctoproject.org > https://lists.yoctoproject.org/listinfo/yocto -- ——————————————— Josef Holzmayr Software Developer Embedded Systems Tel: +49 8444 9204-48 Fax: +49 8444 9204-50 R-S-I Elektrotechnik GmbH & Co.
