 [toolchain]
 # We try to stick to a toolchain version that is widely available on popular distributions, so that most people
 # can use the toolchain that comes with their operating system. But if there's a feature we miss badly from a later
-# version, we can consider updating. As of this writing, 1.60 is available on Debian 'experimental' but not yet on
-# 'testing' or even 'unstable', which is a bit more cutting-edge than we'd like. Hopefully the 1.60 packages reach
-# 'testing' soon (and similarly for the other distributions).
-# See https://tracker.debian.org/pkg/rustc for more details on Debian rustc package.
