# Release notes
### 2025.11.21
### New Features:
- Added SPDX-License-Identifier: MPL-2.0 to source files
- Calculate Eta3 supports all cluster types
- interpolation class supports using cross eta3x3 and eta3x3 on full cluster as well as eta2x2 on full cluster
- interpolation class has option to calculate the rosenblatt transform
- reduction operations to reduce Clusters of general size to 2x2 or 3x3 clusters
- `max_sum_2x2` including index of subcluster with highest energy is now available from Python API
- interpolation supports bilinear interpolation of eta values for more fine grained transformed uniform coordinates
- Interpolation is documented
- Added tell to ClusterFile. Returns position in bytes for debugging
### Resolved Features:
- calculate_eta coincides with theoretical definition
### Bugfixes:
- eta calculation assumes correct photon center
- eta transformation to uniform coordinates starts at 0
- Bug in interpolation
- File supports reading new master json file format (multiple ROI's not supported yet)
### API Changes:
- ClusterFinder for 2x2 Cluster disabled
- eta stores corner as enum class cTopLeft, cTopRight, BottomLeft, cBottomRight indicating 2x2 subcluster with largest energy relative to cluster center
- max_sum_2x2 returns corner as index
### 2025.8.22
Features:
- Apply calibration works in G0 if passes a 2D calibration and pedestal
- count pixels that switch
- calculate pedestal (also g0 version)
- NDArray::view() needs an lvalue to reduce issues with the view outliving the array
Bugfixes:
- Now using glibc 2.17 in conda builds (was using the host)
- Fixed shifted pixels in clusters close to the edge of a frame
### 2025.7.18
Features:
- Cluster finder now works with 5x5, 7x7 and 9x9 clusters
- Added ClusterVector::empty() member
- Added apply_calibration function for Jungfrau data
Bugfixes:
- Fixed reading RawFiles with ROI fully excluding some sub files.
- Decoding of MH02 files placed the pixels in wrong position
- Removed unused file: ClusterFile.cpp
### 2025.5.22
Features:
- Added scurve fitting
Bugfixes:
- Fixed crash when opening raw files with large number of data files
