+## [v492.0](https://github.com/VERITAS-Observatory/EventDisplay_v4/releases/tag/v492.0) - 2025-10-21
+
+### Bugfixes
+
+- Fix segmentation fault when exiting on error due to an empty tree in anasum. ([#286](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/286))
+- Limit number of errors printed when reading faulty VBF files to avoid TB large log files. ([#298](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/298))
+
+### New Feature
+
+- Introduction of average zenith angle calculation per run in VTMVAEvaluator (fAverageZenithPerRun, calculate_average_zenith_angle()). ([#281](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/281))
+- Introduced new functionality for reconstructing events using any three telescopes out of four (primarily for Monte Carlo data and effective area calculations).
+  Added new class: `VMeanScaledVariables` for mean scaled variable calculations.
+  Updated VDispAnalyzer and VSimpleStereoReconstructor to support new reconstruction modes and calculation methods.
+  Updated VInstrumentResponseFunctionRunParameter and related code to include new parameters for 3-telescope reconstruction. ([#289](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/289))
+- Add new command line parameter `--minpedestalevents` to set the minimum number of required pedestal events (default: 50). ([#298](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/298))
+
+### Maintenance
+
+- Update SOFA to version 2023-10-11. ([#284](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/284))
+- Changes in tree structure and variable types to reduce size of output trees (mostly due to change of doubles to floats; removal of unused variables); reduction is on storage requirements is ~25%. ([#288](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/288))
+- Replaced many ROOT auto-generated header/source files (e.g., CData.h, CEffArea.h, CRunSummary.h, Cshowerpars.h, Ctpars.h, Ctelconfig.h) with hand-edited or cleaner C++ code, improving maintainability and readability. Moved implementation code from `.C` files to `.cpp` files, and deleted the old `.C` files.
+  Adjusted several functions and constructors to reflect changes in how data and reconstruction methods are handled (e.g., CData and related classes now use cleaner, more explicit constructors).
+  Functions that previously accepted "version" or "short" flags via integers now use explicit booleans for clarity.
+  Removed the CEffFit class and related files.
+  Pruned unused variables and methods, including some internal variables in VTMVAEvaluator, VTableLookupDataHandler, and others.
+  Removed outdated warnings, TODO comments, and deprecated features. ([#289](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/289))
+- Introduce towncrier for changelogs. ([#300](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/300))
+- Fix github action worklows to compile Eventdisplay. Add cpp11 workflow. ([#307](https://github.com/VERITAS-Observatory/EventDisplay_v4/issues/307))
