New description:

 A new release of attrs has deprecated some APIs Tahoe-LAFS was using.

 I believe these are the relevant warnings:

 {{{
 /.../allmydata/test/storage_plugin.py:107: DeprecationWarning: The usage
 of `cmp` is deprecated and will be removed on or after 2021-06-01.  Please
 use `eq` and `order` instead.
 /.../allmydata/test/storage_plugin.py:110: DeprecationWarning: The usage
 of `cmp` is deprecated and will be removed on or after 2021-06-01.  Please
 use `eq` and `order` instead.
 }}}
