Quartz.NET 3.18.2 is a maintenance release that stabilizes the dashboard introduced in 3.18.0, fixes several scheduling correctness bugs, and speeds up cron next-fire-time computation. It is a drop-in upgrade from earlier 3.18.x releases — no breaking changes and no database schema migrations.

Highlights

• Type-load failures no longer stall the whole scheduler — a trigger or job whose type failed to load could throw inside AcquireNextTrigger and block acquisition of every other trigger. The faulting trigger is now isolated so the rest keep firing. (#3108)
• "Reschedule next" misfire policies no longer fire immediately — after a misfire, the reschedule-next policies could fire once right away instead of waiting for the next scheduled time. (#3100)
• Named-scheduler JSON config is honored — schedules defined under the root Quartz configuration section were not loaded for named schedulers. (#3113)
• Dashboard fixes — authorization policy no longer leaks to host-app endpoints (#3067); static assets and a custom DashboardPath work under a fail-closed FallbackPolicy, and the Blazor circuit is allowed anonymous access under the same policy (#3098, [#3120]); trigger and calendar JSON deserialization is fixed (#3102); and JobDataMap and SimpleSchedule trigger details now display correctly (#3132).
• MySQL FORCE INDEX fix — schema-qualified table prefixes produced a malformed FORCE INDEX hint. (#3086)
• Faster cron scheduling — cron next-fire-time computation gains a bitmask fast path and avoids needless DateTimeOffset churn in the hot loop. (#3126, [#3129])
• Smaller enhancements — health-check tags can now be passed to AddQuartzServer (#3112), and new public helpers make plugin configuration extensible (#3104).
