## 0.11.1-rc1

Released 2022-04-04.

New

* The `dump` command now also copies the stored trust anchor certificates.
  The certificates are named in the same way as they are internally using
  the hash over their URI. Please consult the [manual][dump-manual] for
  details. ([#740])

Bug Fixes

* The `dump` command now removes the internal header before copying
  the objects retained by the RRDP collector, i.e., the files copied into
  the `rrdp` sub-directory now contain the actual DER encoded data only.
  ([#735])
* Correctly set the idle time for TCP keepalives on incoming RTR
  connections on systems that support it. ([#736])
* Fix an encoding error in the `/delta-json` output. ([#737])
* Truncate the PID file before writing the current PID to it. ([#738])
* Exit with a status of 1 if an error happened. ([#739])
