Release LoadGen Api, Appliance and MCP Server: 1.0.0.11851

LoadGen General

• No general changes in this release.

LoadGen Api

• [#8546] Fixed Webrecorder / Web Testing load tests against a Core agent never starting — the agent looped its heartbeat indefinitely with no WebTesting Started line and users stuck at 0 ok / 0 fail / N wait. The API now floors a Core agent's session-stream count at one when the configured value is zero (with a warning in the log if the floor kicks in), and it now extracts data sources (Sheets and Text Blocks) directly from the recorded script bundle and forwards them to the Core agent in the user payload, so recorded steps that reference a sheet column or text block no longer fail with "Datasource does not exists" once the test starts dispatching.
• Added Sheets=N, TextBlocks=M to the API-side dispatch log so the per-test counts can be cross-checked against the agent's Set DataSources (N) line for future triage.
