Exceptionless 8.7.0

Exceptionless 8.7.0 adds JavaScript source map symbolication, modernizes the web API implementation with Minimal APIs and Foundatio.Mediator, and improves event investigation, saved views, OAuth reliability, documentation search, and production operations.

JavaScript Source Map Symbolication

  • Symbolicates JavaScript error frames before stack signatures are calculated.
  • Automatically discovers public source maps from response headers, sourceMappingURL, and conventional .map URLs.
  • Adds project-scoped upload, list, and delete APIs plus a Svelte Project Settings experience for private source maps.
  • Adds least-privilege source-maps:write tokens for CI/CD uploads.
  • Applies bounded downloads, validation, storage quotas, caching, cleanup, and public-network protections.

API, Security, And Reliability

  • Migrates the web API from MVC controllers to Minimal API endpoint adapters and Foundatio.Mediator while preserving existing routes and HTTP behavior.
  • Allows recently rotated MCP OAuth refresh tokens to be reused during a bounded grace period without weakening grant-family revocation.
  • Prevents sensitive startup configuration from being destructured into logs while preserving sanitized operational diagnostics.
  • Refreshes event, session, stream, and stack grids after deletions and reconnects.
  • Fixes idle-resume visibility listener churn.

Event Investigation And Saved Views

  • Improves event detail layout and adds project, tag, and stacking diagnostics.
  • Adds optional Project and Tags columns and simplifies column-picker and tag interactions.
  • Fixes predefined saved-view synchronization, filter reset and navigation, and legacy stack saved-view comparison.

Website And Operations

  • Improves generated documentation search, keyboard navigation, mobile layout, and error reporting.
  • Adds a discoverable Client Setup path with quick-copy server URL and API key values.
  • Fixes production synthetic monitoring and configures the production contact recipient.
  • Avoids local Aspire port conflicts.
  • Aligns production Redis storage and adds Redis metrics collection in SigNoz.
