Exporter release 1.0.0b56

[Radhika Gupta (rads-1996)]

1.0.0b56 (2026-08-05)

Features Added

• Retry payloads for which request is sent successfully but no response is received, per SPEC.
  (#47870)

Bugs Fixed

• Propagate main agent attribute to child spans
  (#47950)
• Live Metrics now honors the APPLICATIONINSIGHTS_AUTHENTICATION_STRING environment variable for AAD
  authentication as a fallback when no explicit credential is supplied and local authentication is disabled.
  (#48284)
• Fix a memory leak where exporters registered as OneSettings configuration callbacks were retained for the
  process lifetime; bound-method callbacks are now held via weak references so discarded exporters can be
  garbage collected.
  (#48379)

Other Changes

• Simplify OneSettings change detection to use ETag-based mechanism instead of change version tracking to reflect spec update
• Change OneSettings log messages from warning to debug level to reduce noise for users with firewalls
  (#47949)
• Harden OneSettings configuration manager and worker: handle non-retryable HTTP errors by slow-polling instead of retrying, fix worker holding its lock across network I/O, make shutdown a soft reset that leaves the singleton reusable, and make callback registration thread-safe and initialization-independent
  (#48027)
• Align OneSettings feature-flag evaluation with the control-plane schema: use full-name os/rp/attach values, add ikey and region conditions, require exact single-value matches (removing list and version-range support), and only honor a ver condition when a matching component is also present
  (#48059)
• Support remote toggling of local (offline) storage via the OneSettings FEATURE_LOCAL_STORAGE feature flag: the control plane can disable or re-enable disk-backed retry storage at runtime, but never overrides an explicit disable_offline_storage=True user opt-out. Statsbeat storage is decoupled from the user setting (always off), while customer-sdkstats honors the user setting and follows the remote toggle.
  (#48379)
• Enable the OneSettings control plane in the base exporter: it now starts the configuration worker and registers the process profile (os/rp/attach/component/version/region/ikey) so feature flags can be evaluated. _ConfigurationManager.initialize merges profile fields first-wins across calls, letting a dependent component (e.g. the Azure Monitor distro) set component before the exporter contributes ikey/region.
