What is jwst?

JWST's calibration pipeline extended adaptive trace modelling across its spectrographs

Version 3.0.0, the DMS B13.0 operational build, is the substantive release in this window. It extends the adaptive_trace_model step to NIRSpec MOS, fixed-slit and BOTS modes plus MIRI LRS, adds multiprocessing that cut one NIRSpec IFU case by roughly a factor of seven, and introduces chromaticity correction for NIRSpec IFU data via a new reference file type. It also removes several internal-only step parameters as breaking changes. The four release candidates preceding it contain only dependency pins and changelog freezes.

What is Meshes.jl?

Meshes.jl ships one pull request at a time, and most of them are geometry correctness

The library releases at a rate of several patch versions a week, each carrying a single merged pull request. The current run is evenly split between performance work - an optimised centroid and measure for planar polygons, further GJK tuning, a neighbour-search refactor - and correctness fixes to the same primitives, including a wrong centroid calculation and PolyArea incorrectly adding inner-ring area.

JWST's calibration pipeline extended adaptive trace modelling across its spectrographs

◆ Current state

Version 3.0.0, the DMS B13.0 operational build, is the substantive release in this window. It extends the adaptive_trace_model step to NIRSpec MOS, fixed-slit and BOTS modes plus MIRI LRS, adds multiprocessing that cut one NIRSpec IFU case by roughly a factor of seven, and introduces chromaticity correction for NIRSpec IFU data via a new reference file type. It also removes several internal-only step parameters as breaking changes. The four release candidates preceding it contain only dependency pins and changelog freezes.

◆ Where it's heading

Development is organised around periodic DMS operational builds rather than continuous delivery, with release candidates used purely to freeze dependencies. The direction inside the pipeline is toward per-mode calibration sophistication - trace modelling and chromaticity corrections that were previously unavailable or mode-limited - alongside a steady cleanup of parameters that only ever existed for internal plumbing.

◆ Prediction

Expect adaptive trace modelling to keep expanding across the remaining instrument modes, and the multiprocessing work applied there to spread to other slow steps. Further breaking removals of internal-use parameters are likely while the 3.x major version is open.

Meshes.jl ships one pull request at a time, and most of them are geometry correctness

◆ Current state

The library releases at a rate of several patch versions a week, each carrying a single merged pull request. The current run is evenly split between performance work - an optimised centroid and measure for planar polygons, further GJK tuning, a neighbour-search refactor - and correctness fixes to the same primitives, including a wrong centroid calculation and PolyArea incorrectly adding inner-ring area.

◆ Where it's heading

The pattern of optimising a function and then correcting its definition a release later suggests the core geometric predicates are being systematically revisited rather than extended. This is depth work on a settled API: the same handful of operations getting faster and more numerically defensible, including on non-standard number types like BigFloat.

◆ Prediction

Expect the single-PR cadence to continue through the remaining core predicates, with measure and centroid variants for further geometry types the most likely targets. Nothing in these entries points to new geometry abstractions.
