  • Support incoming SRM^S04 and SRM^S05 messages (appointment cancellation)

0.16.0 – 2019-10-15

0.14.0 – 2019-08-07

  • Support for configuring receiving_application and receiving_facility (MSH-5, MSH-6) per connection for outgoing HL7 messages.

0.13.7 – 2019-06-20

  • FIXED: patients where zip, phone numbers or insurance number encrypted as integers would crash the gateway.

0.13.6 – 2019-06-03

  • Use 99SAMEDI-RESOURCE instead of SAMEDI-RESOURCE in AIG-3-3 to not generate invalid HL7 messages. SAMEDI-RESOURCE is still accepted in incoming AIG/AIL/AIP segments.

  • FIXED: patients with “insurance_company” set to “public” or “private” would break during ADT message handling.

0.13.5 – 2019-05-21

  • Support AIP/AIL/AIG segments in SRM messages: When updating an existing appointment in samedi with an SRM message, it’s now possible to override the booking logic by sending appropriate resource segments. This updates the booked resources on that appointment to be exactly as sent.

0.13.4 – 2019-05-20

  • Add a configuration option mllp.sender.peer_error_handling = "ignore". If set, the program will not terminate when it receives a MSA message with AE or CE status and the message will not be retried.

0.13.3 – 2019-05-15

  • hl7gateway instances now periodically announce their status when running normally.

0.13.2 – 2019-05-14

  • Moved default configuration into non-roaming %ProgramData%.

  • FIXED: multiple incoming connections on the same channel work now.

  • FIXED: service restart would sometimes not work when there were network errors during program initialization.

  • FIXED: logging to the windows event log didn’t work.

0.13.1 – 2019-05-02

  • Note: existing integrations that send SIU messages to samedi with AIG-3-4, AIL-3-4 or AIP-3-4 need to be updated to keep this field empty or to have an actual resource xref there (this field was previously ignored).

  • Change parsing of incoming AIG/AIL/AIP segments.

    • AIG-3-1 can now describe a samedi Resource ID. For this AIG-3-3 must have the value SAMEDI-RESOURCE
    • If AIG-3-4 is set, it will be interpreted as samedi resource xref. This will always take precedence over AIG-3-1. (the same applies to AIL and AIP segments)
    • Accordingly, in outgoing SIU messages, AIG-3-3 is now set to SAMEDI-RESOURCE to indicate that AIG-3-1 is a resource ID, not a resource xref

  • Save access token in the state file by account name instead of user name

0.13.0 – 2019-04-29

  • hl7gateway instances now use an access token to authenticate themselves with app.samedi.de

0.12.9 – 2019-04-17

  • Duration is calculated differently for appointment types that are configured with negative start offsets
  • Moved the public website to repo.samedi.de/hl7gateway

0.12.6 – 2019-04-05

  • FIXED: do not send patients birthdate in outgoing PID segments when it is before the year 1900.

  • FIXED: when an xref was used in different resources across multiple samedi accounts it would only be associated with a single account.

  • Support multiple independent MLLP connections.

  • Remove dump_dir configuration option to write HL7 messages to a directory. Use samedi.log_file to log messages.

0.12.5 – 2019-04-02

  • Skip patient birthdate in PID, when the year is less than 1900

0.12.4 – 2019-03-26

  • Use “.br” escape sequence instead of newlines when sending messages to KIS

0.12.3 – 2019-03-21

  • Do not attempt to book appointments into ressources that are shared from another account.

0.12.2 – 2019-03-20

  • Add samedi.log_file configuration option.

0.12.1 – 2019-03-06

  • Support more fields in SRM-S02 messages:
    • Allow ignoring availability calculations when updating appointments with force^yes in APR-5.
    • Support updating appointment duration with ARQ-9/ARQ-10.

0.12.0 – 2019-02-26

  • Support incoming SRM^S02 messages for updating appointments in samedi.
  • Don’t send U+200C characters in NTE fields of appointment comments.
  • Make UTF-8 the default MLLP message encoding for new installations

0.11.0 – 2019-02-05

  • Use MSH-9-1 and MSH-9-2 exclusively for recognizing messages. Stop using MSH-9-3 (Message Structure)
    • SIU-Messages now don’t need to include SUI_S12 in MSH-9-3 any more.
    • Only S12 - S15 messages are now handled. Older versions would silently accept other types of SIU-Messages.
  • outgoing SIU messages now send AIG||X segments inside an RGS||X group for each unchanged resource in an appointment.
  • FIXED: SIU messages now always contain at least one RGS segment.

0.10.4 – 2019-01-15

  • FIX: listen for shutdown signal even while syncing is not yet finished
  • Send recreate_if_exists parameter for events when creating them. When gateway sends a request to create an event, in case the event with such xref already exists, platform will cancel it and create a new event with that xref.

0.10.3 – 2018-11-20

  • FIX: put outgoing appointment namespace in SCH-2-2 as described, not SCH-2(2)-1

0.10.2 – 2018-11-20

  • Add a configuration option patients_polling_enabled to disable sending of ADT messages
  • Add a configuration option appointments_polling_enabled to disable sending SIU messages
  • deprecated polling_enabled configuration option, which now disables outgoing ADT and SIU messages.

0.10.1 – 2018-11-15

  • Add a configuration option “appointments_namespace” to “samedi” section. When present, this will be put to SCH-2-2 of outgoing SIU messages.

0.10.0 – 2018-11-06

  • Drop support for service installation in Unix/macOS.
  • Make windows service handling more robust:
    • Add a command line option “workingDirectory” to make relative paths in configuration work. (they would be relative to “%WINDIR%/System32” before)
    • Log errors during startup to Windows EventLog.
    • Configure automatic restart of the service during installation.
  • MLLP: don’t attempt to connect automatically during startup. Connect when the first message needs to be sent.

  • retry network requests to make the program more robust
  • Support “enhanced mode” for Acknowledgements, allow outgoing messages to be acknowledged with CA/CR/CE codes in addition to AA/AR/AE.
