Monthly summary for 2025-11 focusing on the databricks/terraform-provider-databricks work. Delivered a stability-focused fix in integration tests by implementing user agent deduplication to prevent the Terraform version from being appended multiple times to the global user agent string. The change uses sync.Once to ensure the Terraform version is added only once, addressing duplication observed during provider initialization in the muxed provider architecture (SDKv2 + Plugin Framework). This reduces test noise, improves CI reliability, and ensures more accurate usage analytics. Related commit highlights the exact changes: 4e0d459a0911d436ad3e94befebe52716a888cdc. Business value includes more stable test results, faster feedback loops, and clearer logs for end users and developers.
