Exceptionless 8.7.2

Exceptionless 8.7.2 improves saved views and event exploration, upgrades the MCP integration, reduces unnecessary telemetry volume, and strengthens billing, validation, and account reliability. It also includes a series of UI polish, accessibility, and operational improvements.

Event Exploration And Saved Views

  • Adds resizable saved-view columns and improves detection and publication of column-bound changes.
  • Creates missing predefined saved views during force updates and hardens migration execution for legacy data.
  • Prevents duplicate event-list refreshes during reconnects, focus changes, route transitions, and other reactive lifecycle events.
  • Fixes event and stack detail navigation, nested session event links, and stale stack details when switching projects.
  • Preserves truncated tag values and improves long-tag overflow, tag interactions, and event-query behavior.
  • Updates the event-list implementation to TanStack Query and refreshes frontend dependencies.

MCP And API Reliability

  • Upgrades the MCP C# SDK to v2 and adopts the native stateless MCP v2 transport.
  • Improves MCP scope resolution, context isolation, project resolution, and stateless tool contracts.
  • Validates MCP tool metadata and filter fields more strictly while preserving supported event filters.
  • Improves predefined saved-view validation and prevents queued saved-view slug collisions.
  • Fixes organization and project name validation and repairs invalid verified-user email state.

Billing And Operations

  • Ensures billing credits are reused correctly across plan changes.
  • Fixes a billing downgrade, recharge, and suspension race.
  • Reduces OpenTelemetry ingestion volume by removing unused scraped metrics and unnecessary messaging spans.
  • Upgrades the SigNoz Kubernetes infrastructure chart and keeps metric collection focused on useful signals.
  • Updates saved-view HTTP samples and migration behavior for more reliable deployments.

User Interface And Accessibility

  • Improves long-tag popover interactions and table column sizing.
  • Fixes ghost-button hover contrast in light and dark themes.
  • Improves premium-search enforcement and Svelte upgrade guidance.
  • Expands Playwright coverage for operator workflows.
  • Adds locale-specific coverage for memory formatting.
