FYI: The status of the rust-core-arch source package in Debian's testing distribution has changed. Previous version: 0.1.5-4 Current version: (not in testing) Hint: <https://release.debian.org/britney/hints/auto-removals> Bug #976467: rust-core-arch FTBFS error[E0635]: unknown feature `mmx_target_feature` The script that generates this mail tries to extract removal reasons from comments in the britney hint files. Those comments were not originally meant to be machine readable, so if the reason for removing your package seems to be nonsense, it is probably the reporting script that got confused. Please check the actual hints file before you complain about meaningless removals. -- This email is automatically generated once a day. As the installation of new packages into testing happens multiple times a day you will receive later changes on the next day. See https://release.debian.org/testing-watch/ for more information.
