Version 5.7.6 released 27-Jul-2022
- added a low priority option when subscribing via websocket. This allows the yamcs-web to keep connected if there is high incoming data rate, at the expense of some of the messages not displayed.
- bug fix parameter archive retrieval end conditions (sometimes it would send data that was past the stop time of the request)
- allow java algorithms to specify their input list (if for any reason is not available in the xtce definition)
Version 5.7.5 released 24-Jul-2022
- CFDP fixes
- the pendingAfterCompletion parameter can be specified now
- when starting a new download the number of pending downloads excludes the ones just finished and also the uploads. The number is used to compare with the maxNumberDownloads parameter - if the maximum would be exceeded a new download transfer would not be initiated and the respective PDU dropped
Version 5.7.4 released 15-Jun-2022
- added an option to the /api/stream-archive/{instance}:streamParameterValues (which extracts parameters using replays) to filter the packets based on the tm links
on which they have been originally received.
For example typically a different link is used to receive dump (recorded on-board) packets; This option can be used to extract parameters only from those. Or could be used to retrieve only from the realtime packets skipping the dump.
Version 5.7.3 released 9-Jun-2022
- CCSDS TM/TC randomizer: fixed the interpretation of offset/length parameters (may affect custom encoders which want to randomize/derandomzie only parts of the frames).
- Allow custom (Java) algorithms to provide the list of output parameters at runtime (rather than in the MDB definition) such that the algorithms are not skipped at replay time if no output parameter has been declared in the MDB def.
- MDB: added internal support for ToString allowing to define how to display the values of parameters (will be implemented in the future in yamcs-web and Yamcs Studio)
- yamcs-web:
- Show favicon badge when there is an alarm
- Add group action for queues
- Show process tree on system page
- Add Command detail page
Version 5.7.2 released 3-Jun-2022
- yamcs-web: fix render issue with enumerated and command aggregate arguments
Version 5.7.1 released 30-May-2022
- Allow 200 aliaes in the yaml files (used to be 50). The number can be configured via the java property org.yamcs.yaml.maxAliases
- yamcs-web: Show detail field on links page
- yamcs-client: fix generation of command source for command with binary arguments
- fixed units in the data links synthesized parameters (e.g. /yamcs/<hostname>/tm_realtime/packetRate)
Version 5.7.0 relased 27-May-2022
- implemented backend support for raw TCs (telecommands which are not generated from the mission database) and bypassing the postprocessor.
- Renamed several java packages to avoid having the same package in different jars (this practice has been discouraged since the introduction of java modules)
The "org.yamcs.xtceproc" and "org.yamcs.xtce" in yamcs-core has bene renamed to "org.yamcs.mdb". May require update of custom plugins if they use classes from those packages.
- Various tweaks and fixes

- Old-style websocket is now fully removed (use new-style)
- Tags are gone (use timeline)
- Various tweaks and fixes
Version 5.5.7 released 3-Feb-2022

- minor tweaks and fixes
Version 5.5.2 released 22-Jun-2021
- Fixed XTCE reference solver of types para->Type->BaseType which were defined in reverse order in different files.
- Fixed parameter archive retrieval of raw values only.
- yamcs-web: fixed replication page not showing info.
Version 5.5.1 released 8-Jun-2021
- Fixed (again) the name of the packets shown on yamcs-web front page (TM statistics)
- Fixed an XTCE reference solving bug
- Fixed the retrieval from parameter archive with the option useRawValue=true
Version 5.5.0 released 1-Jun-2021
- Added algorithm status and tracing (currently only working for global algorithms)
- Added support for XTCE transmission constraints and verifiers (using MatchCriteria, BooleanExpression...)
- Added java-expression algorithms
- Added types to system parameters
- Fixed the realtime parameter archive - it can now be used as a preferred configuration for all systems receiving only realtime data (e.g. testing in an EGSE/Lab setup)
- CCSDS Frame Processing: allow plugging user defined virtual channels handlers
- Fixed the Parameter Archive to reconstruct aggregate and array parameters out of their components (which are stored separately in the archive)
- minor tweaks and fixes
Version 5.4.5 released 5-Apr-2021
- Fixed a bug causing the rejection of aggregates with enumeration members when used as command arguments
Version 5.4.4 released 2-Apr-2021
- Fixed a bug in the TM partitioning flags causing the homepage of Yamcs to not display the packets beyond the top level.
- Fixed a typo in reading the TCO configuration causing the defaultTof option to be ignored.
Version 5.4.3 released 16-Mar-2021
- Added some REST calls for getting more detailed information about parameter archive (can be used to investigate problems of missing data).
- Added possibility to trace algorithm executions.
- minor tweaks and fixes
Version 5.4.2 released 9-Mar-2021
- Fixed the container name used as partition in the tm table. XtceTmRecorder will only use as partition (pname column in the tm table) the containers directly inherited from the root container defined on the stream on which the TM packet is received. Previously, if a container included another container inside, this last one would have been used as partition and also appear as the name of the packet in the home page of yamcs-web.
- Added a maxValues parameter to the parameter range request
- Added an API for instance reconfiguration - the instances created from templates can now be updated following template changes, or with modified template variables.
- Allow aggregate values (not only members) to be used in Java algorithms (not yet available in Python or Javascript algorithms - these have to make reference to aggregate members)
- minor tweaks and fixes
Version 5.4.1 released 17-Feb-2021
- CFDP: allow to configure the inactivityTimeout
- changed yamcs systemd script to not depend on bash being the system shell
- add support for web response filtering
- added a minRange option to the parameter range request allowing to limit the number of ranges returned. This is done by aggregating data into multi value range.
Version 5.4.0 released 10-Feb-2021
- Generalized file transfers: allow different than CFDP file transfer services to be implemented offering the same external API.
- Added displayName/email attribute support to YamlAuthModule
- Added queueing support to CFDP - files can be queued for later upload
- Allow multi-purpose links (e.g. both TM and TC)
- Added a perftest example useful to asses the performance of Yamcs
- Added a bidirectional TCP TM/TC link
- Save the link name in the tm table - this allows later to find out packets received via a certain link
- The usage of time of flight estimatro (TOF) in the time correlation service (TOC) has been made optional (a config setting can be used to set the tof to a fixed value)
- yamcs-web: show an view of the replication status
- yamcs-web: moved the buckets out of the admin area
- various other tweaks and fixes
Version 5.3.5 released 20-Dec-2020
- Fixed a bug related to CFDP transfer storage in archive (the entity id was not saved for the incoming transfers)
Version 5.3.4 released 17-Dec-2020
- Fixed a bug in replication introduced in version 5.3.2 when allowing tuples to contain null values.
- Improved XTCE support for command verifiers, demonstrated with the PUS simulator.
Version 5.3.3 released 14-Dec-2020
- Added a simple PUS simulator to exemplify the usage of the time correlation (TCO) service with a free running on-board clock.
- Save the OBT (value of the free running on-board clock) in the tm table.
- TCP and UDP packet links populate the ERT (Earth Reception Time) field of the TM packets with the local mission time as this is required by the TCO service.
Version 5.3.2 released 11-Dec-2020
- Reorganized the service creation and initialization such that a pre-processor (which used to be initialized earlier) can have access to them.
- CfsPacketPreprocessor can optionally use the time correlation service to verify the time extracted from the packet.
- Removed the clock name from the time correlation service, use the serviceName instead.
Version 5.3.1 released 8-Dec-2020
- CFDP improvements
- minor tweaks and fixes
Version 5.3.0 released 25-Nov-2020
- Added a bulk load option to be used by the command yamcs tables load. It does not update the histograms and also disables the RocksDB WAL (write ahead log) resulting in faster loads.
the histograms have to be rebuilt manually after this.
- Introduced a table format V3 which sorts properly the negative numbers and also the strings
- most Yamcs tables use a timestamp as primary key and the timestamps before 1970 are represented as negative numbers and thus were not sorted properly
- the old format V2 is still supported but new tables created with this Yamcs version will not be readable by a previous Yamcs vsersion.
- Preview feature: secondary indices on tables; not used for regular Yamcs tables (tm, events, cmd_history, etc) but it will be used for the soon to come Yamcs timeline.
- Preview feature: time correlation service; can be used to correlate a free running on-board clock with the ground time.

- yamcs-xtce:
all parameter and argument types need to be constructed through builders.
all data encodings need to be constructed through builders.
support the baseType XTCE property which allows a type to inherit properties from another type.
AbsoluteTimeParameterType uses java Instant as initial value (rather than Yamcs times)

calibrate (raw->eng value) them inside the processor rather than before being injected in the stream.
This means the parameters are stored in the L0 archive also in the initial form (could be raw+eng,only raw or only eng) and they are calibrated (using the current MDB) for each replay
Of course ParameterArchive will store them calibrated.
