This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use. * **rugnux: significantly better quality of results, and faster.** A large rework of integration, scaling, merging, geometry refinement and space-group determination, together with measurements the program previously made no attempt at - the direct beam before indexing, the beam stop, the goniometer rotation scale, and the stretches of a sweep the crystal did not deliver. A rotation dataset typically gains observations at better <I/sigma> and R_meas, and every `mx` and `scale` run writes a `<prefix>_report.txt` results report modelled on XDS's `CORRECT.LP`. Many defaults moved with it: spot detection is self-calibrating, beam-stop detection and rotation geometry post-refinement are on, resolution limits default to as far as the detector reaches, and ice-ring handling engages only where the crystal is measured to have ice. * **jfjoch_viewer:** the beam-stop shadow, the detector calibration and the beam-centre measurement are reachable from "Analyze dataset"; the settings panel reports how the sample moved and how polarized the beam was; image rendering and interaction are faster. * **Performance:** bitshuffle+LZ4 images are decoded on the GPU rather than on the host, with the bitshuffle inverse fused into preprocessing so the decompressed frame is never held in device memory. * **Broker, writer, packaging and build:** image-slot lifetime and locking fixes, per-image datasets sized by the images actually written, the Debian/Ubuntu broker package renamed to `jfjoch`, and `image_analysis` compiling under MSVC again. **Breaking change to the rugnux command line:** * `--azint-only` and `--scale` are **removed**, replaced by `--mode azint` and `--mode scale`; the full pipeline is `--mode mx` and remains the default. A script passing the old flags now fails with the list of valid modes rather than silently running the wrong one. * `-t`/`--stride` is **refused on rotation data**: skipping frames cuts every reflection's rocking curve, so the combined fulls and their partiality would be measured over frames the sweep never recorded. Select a contiguous range with `-s`/`-e` instead. `--mode azint` and `--force-still` still take a stride. **Breaking changes to OpenAPI** - regenerate the client (`jfjoch-client` 1.0.0-rc.161, `frontend/src/client`) or read the affected fields as optional: * `image_scale_b` is removed from the `plot_type` enum, so a client requesting that plot now gets an error rather than a curve. * `azim_int_settings.high_q_recipA`, `spot_finding_settings.high_resolution_limit` and `spot_finding_settings.low_resolution_limit` are no longer `required`. All three mean "no limit at that end" when unset and are omitted from the response instead of carrying a placeholder value, which raises in a client generated from an rc.160-or-earlier spec. A value of 0 is still accepted and means the same thing. **Breaking changes to the stored formats** - a consumer reading these fields must treat them as optional: * The per-image image-scale B factor is no longer computed, so `/entry/MX/imageScaleBFactor` is absent from newly written HDF5 files and the corresponding key is absent from the CBOR DataMessage and END blocks. Files written by rc.160 and earlier still contain it and still open; nothing in the pipeline reads it any more. * `_reflns.jfjoch_diffrn_ISa` now carries the whole-range `1/sqrt(a*b)` that XDS's ISa denotes, and the error-model `a` and `b` are reported in XDS's convention; the strong-reflection asymptote moves to `_reflns.jfjoch_diffrn_ISa_asymptotic`. **A file written by an earlier version carries the asymptote under the plain `ISa` name.** Reviewed-on: #71 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch>

third-party components, acknowledged below as required by their licenses.
This file is the human-readable manifest. The verbatim license texts live in the

These are downloaded by CMake (FetchContent / ExternalProject) during the first configure and
linked into the Jungfraujoch executables.

Frontend (npm) dependencies
The React/TypeScript frontend (frontend/) bundles a large transitive tree of npm packages,
overwhelmingly MIT/ISC/BSD/Apache-2.0 licensed. Their full notices are generated automatically:
cd frontend && npm run licenses # writes dist/THIRD_PARTY_LICENSES.txt
The generated file is produced as part of the frontend build target and installed alongside the
served frontend, so the shipped web UI carries its own attribution.
Notes on weak-copyleft and attribution-sensitive components
- MPL-2.0 (Eigen, GEMMI, libzmq, traccc): file-level copyleft. GEMMI is vendored in
gemmi_gph/in trimmed form; libzmq is fetched at build time; Eigen is provided externally (header-only). The corresponding source is available from each project upstream. - traccc is the one entry that is not a vendored directory. Its sparse connected-component
labelling enters two otherwise first-party files:
StrongPixelSet.cppadapts the SparseCCL source, andSpotExtractorGPU.cufollows the design of its GPU counterpart. MPL-2.0 is file-level, so both files name the origin at the top and are covered bylicenses/traccc.txt. See ACKNOWLEDGEMENT.md for the citation. - FFTW is GPL-2.0-or-later — compatible with, and absorbed by, this project's GPL-3.0 license.
- Apache-2.0 components: where upstream ships a
NOTICEfile, it is reproduced in the correspondinglicenses/text. - Qt (LGPL-3.0) and NVIDIA CUDA (EULA) carry redistribution conditions beyond a copyright
notice; see their dedicated notice files. The verbatim LGPL-3.0 and CUDA EULA texts are bundled
(
licenses/Qt6-LGPL-3.0.txt,licenses/NVIDIA-CUDA-EULA.txt); the CUDA EULA is the one shipped with CUDA Toolkit 12.8 — replace it if you build against a different toolkit version.
