smuxi is obviously not maintained anymore. I am orphaning the package now.

Description:
  Smuxi is an irssi-inspired, flexible, user-friendly and cross-platform IRC
  client for sophisticated users, targeting the GNOME desktop.
  .
  Smuxi is based on the client-server model: The core application (engine) can
  be placed onto a server which is connected to the Internet around-the-clock;
  one or more frontends then connect to the core. This way, the connection to
  IRC can be kept up even when all frontends have been closed. The combination
  of screen and irssi served as example for this architecture.
  .
  Smuxi also supports the regular single application mode. This behaves like a
  typical IRC client; it doesn't need separate core management and utilizes a
  local engine that is used by the local frontend client.

As the maintainer of a build-dependency of smuxi (src:mono), I plan to
soon remove a binary package it relies on,
https://bugs.debian.org/1093237

Unless its build recipe is updated to rely on another package (I
suggested one in the linked bug report), that would probably lead to
the removal of smuxi from the Debian archive.

This is the first time I am in such a situation, and I would not want
to cause a surprise removal of a package I am not maintaining. So
please tell me if anything should be done prior to the actual binary
package removal, in addition to the bug report I already opened.

A new upload of src:mono targeting experimental is currently being
built, that no longer provides mono-runtime-boehm.

Since this is a build-dependency of smuxi, this is going to make it
unbuildable once this src:mono update reaches unstable. This should
happen soon after Trixie release.
