Release Notes

7.0.0

New Features:

  • For security reasons, Node.js has been updated to version 22.13.1. (LSP-41)

  • As of version 7.0.0, SAP Spool printing has been improved to fully comply with the SAP specifications. On how to use it, refer to Configure Output from SAP Spool on Windows or on Linux. The following changes have been implemented:

    • The seal-co-notifier service can send job and device notifications to multiple SAP systems. (PLS-2055)

    • Masterlock of the seal-co-notifier has been abolished. Instead it is locked per rmgId (per LOMS). This enables correct horizontal scaling of the service. (PLS-2102)

    • Device notifications are supported according to the BC-XOM specification. (PLS-2106)

    • In the event of a problem with a printer, the feedback is sent to SAP in an SAP-compliant manner. This makes it clear that the problem was with the printer and not the job. (PLS-2135)

    • SAP ROMS reconfiguration settings are evaluated by the seal-co-notifier service and logged. (PLS-2137)

    • For the BC-XOM certification, job notifications have been modified according to the SAP requirements. (PLS-2138)

    • Device feedback with interval control works according to the BC-XOM specification. (PLS-2143)

    • In a cluster, multiple instances of seal-co-notifier service share their workload. For customers with several IPP or SAP systems, this results in load distribution. (PLS-2167)

    • For the seal-co-notifier service, two new service keys KV_HISTORY_SIZE and KV_STORAGE_TYPE are available to configure the NATS key-value store. (PLS-2171)

    • The seal-co-notifier service uses nwrfcsdk 7.50.15. (PLS-2172)

  • The seal-co-notifier service provides the new Prometheus metric out_ngn_sap_function_calls_total to monitor communication with SAP. For the existing metric out_ngn_sap_notifications_total the label notification_type has been added. (PLS-2168)

  • For container based installations distroless images are available via Github. (PLS-2191)

Bug-Fixes:

  • The firewall.sh script will not start the firewall anymore. (LSP-23)

  • Sometimes BC-XOM notifications to SAP were lost. This error has been fixed. (PLS-1476)

  • The directory of the sapnwrfc.ini file is explicitly set in seal-co-notifier service via the SAPNWRFCINI_PATH environment key. (PLS-2013)

  • The bug has been fixed, where PLOSSYS 4 scaling parameter were not evaluated if not received via IPP. (PLS-2058)

  • If job metadata have been changed by a converter service, the job parameter job.metadata is updated accordingly to be used in the flow of seal-convert-dispatcher service. (PLS-2147)

  • SAP device notifications are fail-safe like job notifications. (PLS-2165)

  • Special characters like umlauts in printer names do not cause errors in the seal-co-notifier service. (PLS-2178)
