Released 2025-06-18.

With this release, Rotonda switches to version 0.6.0 of the roto library. While many things have improved behind the scenes and under the hood, there are no breaking or otherwise noticeable changes for Rotonda users.

An overview of the changes in roto 0.6.0 can be found here.

Released 2025-05-20.

New

• VRP information coming in via RTR updates (both full Cache Resets and Serial responses) now triggers reevaluation of stored prefixes.
• The new vrp_update filter can be used to act upon incoming VRP updates, for example for logging purposes.
• The new rib_in_rov_status_update function can be used to act upon changes with regards to the ROV status of stored routes.
• In roto, lists of ASNs and prefixes can be defined in the new compile_lists function. These lists can be used from all other filters to match on, for example for logging and monitoring purposes.
• A new timestamped_print method is added on the output type in roto.

Other changes

• The file-out logging target now periodically flushes to disk, to prevent information from waiting in the buffer in low traffic scenarios.

Released 2025-04-24.

Breaking changes

• Roto filter names have changed, as dashes are replaced with underscores.

New

• An RTR component is introduced, enabling Rotonda to receive RPKI information from RP software via the RTR protocol.
• Route Origin Validation is available on incoming routes in the 'rib_in_pre' filter using a new rpki.check_rov(..) method. The ROV result is included in responses from the RIB's HTTP endpoint.

Bug fixes

• In some cases, log entries would not actually be written to the output file.
• Under certain circumstances existing more specific prefixes, that were not covered by a requested prefix were returned. This is now fixed.

Known issues

• Performing ROV from roto scripts currently only works on incoming routes, using the VRP data that is available at that moment. New VRP data coming in via VRP does not trigger reevaluation of stored routes yet.

Other changes

• Parsing of certain BMP/BGP fields, specifically BGP Capabilities, are more forgiving to prevent reconnection loops.

Released 2025-01-30.

Breaking changes

• In the embedded roto the define and apply blocks are gone. Users can now define variables and functions throughout the script.

• Arguments to filter-maps in roto have changed: some of them are now implicit.

  See the bundled example in etc/examples for more details.

New

• In the roto language users can now assign variables and functions through the use of let statements anywhere in a roto script.
• In roto, in addition to the breaking changes, there now is support for constants and strings. This enables, amongst other things, customizable logging.
  Several other helper methods on the various types, including ones to format fields to strings, are introduced.
• The new file-out target enables logging to a file in JSON or CSV format.
  Several helpers to log specific features are available, as well as the aforementioned custom logging via strings.
• The mrt-file-in unit can now be configured to process multiple files in sequence, and is able to process the most common message types seen in update MRT files. Furthermore, .bz2 compressed archives can be processed.
  A new API endpoint enables queueing of files.
• Upon re-establishment of a previous BMP session, the previous session information is looked up and re-used. This should reduce memory use, and moreover, prevent confusing results when querying prefixes.
• BMP messages originating from a LocRib are now recognized and stored.

Bug fixes

• Several metric counters were not increased properly.

Known issues

• The "more_specifics" field in a query result may include wrong prefixes.

Other changes

• We no longer build binary packages for Debian 9 "Stretch" and Ubuntu 16.04
  LTS "Xenial Xerus".

Acknowledgements

We would like to very much thank the following people for their (ongoing) input and support in various ways: Tobias Fiebig, Ties de Kock, Lisa Bruder, Ralph Koning, Bruno Blanes.

Bug Fixes

• A non-monotonic clock measurement caused some threads to panic (under
  unknown conditions). These measurements now use a monotonic clock, that can
  not panic.
• The packaged filters.roto.example contained wrongly ordered parameters in
  its filter definitions, resulting in them not being executed. The orders are
  fixed and logging is added.

New

• The MRT component can now read gzipped files. Decompression is triggered for
  files with the '.gz' extension.

Other changes

• A zero-length sysName in a BMP InitiationMessage caused all subsequent
  messages to be marked as hard fails. We now warn on such empty values but
  proceed as usual, because the sysName is not crucial to the process in
  any way.

What's Changed

• Dev Aware PR by @density215 in #95
• Bugfix: use monotonic clock instead of chrono::DateTime in Payload by @density215 in #96
• Merge in recent changes from dev by @DRiKE in #102
• Update Changelog by @DRiKE in #103
• Release 0.2.1 merge by @density215 in #104

Full Changelog: v0.2.0...v0.2.1

Breaking changes

This release contains mostly refactored components, aiming at better
performance and reduced resource requirements.

Most notably, our filter language Roto is now compiled to machine code and
offers user friendly error messages.
