Release Notes for system:inmation 1.26

1.26.7 - September 26, 2017

system:inmation 1.26.7 is now signed with a new code-signing certificate: This affects the automatic update of DataStudio, requiring a manual validation of the new code-signing certificate. Please visit here for more information.

Rectify object locking: Fixes potential unnecessary locking of objects during some operations (checking object existence, fetching certain properties).
Update certhash to match the build certificate
Update digital signature timestamping and verification code to use Comodo’s certificate authentication
Increase parallelism in SQL catalog: Improvements in scaling of cv waits and notifications to number of threads involved.

Fix empty tracking context modifier and missing SCI call user context: Objects created by script could have empty 'created' and 'modified' date fields. TFS #3897
Disconnect data sources on shutdown (e.g. remove OPC groups, etc.): Prevents improper shutdown of OPC servers after Connector disconnection TFS #3950
Safe-guard against same OPC group names between service restarts
Leak the MongoDB connection pool on shutdown: So concurrent operations during shutdown (e.g. incoming network requests for historical data) can still rely on MongoDB functionality.
Fix time series query frame calculation (remove an old historian artefact): Potential for history queries made using Lua to retrieve entire history regardless of time boundries. Could lead to performance issues. TFS #3957
Fix memory leak in time series query code: Clean up of map structures in the rolling history mode in DataStudio. TFS #3962
Confine the shutdown timeout to IO facility only
Fix potential loss of data in time series production store: Purge of time series production store data of objects not yet loaded in I/O model could lead to data loss after Core restart. TFS #3963
