Gradle vs jwst: at a glance
What is Gradle?
A 9.8 milestone arrives before 9.7 ships a final, and the RC train keeps rolling
Gradle's 9.x line is a sustained push on configuration-time performance, and 9.7 is its landmark release: Isolated Projects graduates to incubating, alongside broader Configuration Cache compatibility and more source locations in problem reports. That feature set was fixed at RC1 in mid-July and restated unchanged through RC2 and RC3. The newest tag is not a 9.7.0 final but v9.8.0-M1, a milestone whose one visible change reports invalid toolchain installation paths as warnings through the Problems API.
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.

A 9.8 milestone arrives before 9.7 ships a final, and the RC train keeps rolling
◆ Current state
Gradle's 9.x line is a sustained push on configuration-time performance, and 9.7 is its landmark release: Isolated Projects graduates to incubating, alongside broader Configuration Cache compatibility and more source locations in problem reports. That feature set was fixed at RC1 in mid-July and restated unchanged through RC2 and RC3. The newest tag is not a 9.7.0 final but v9.8.0-M1, a milestone whose one visible change reports invalid toolchain installation paths as warnings through the Problems API.
◆ Where it's heading
The release machinery here is unusually legible: milestones cut a feature set, RC1 announces it, and later candidates repeat the same three highlights while stabilising, with only the contributor list changing between them. Worth noting now is that a 9.8 milestone appeared before a 9.7 final did, so the two lines overlap and the feed will keep interleaving them. The Problems API is the quiet through-line under the Isolated Projects headline — problem-report source locations in 9.7, toolchain path warnings in 9.8-M1.
◆ Prediction
Expect 9.7.0 final to ship with its three highlights unchanged, and the 9.8 milestones to keep routing more diagnostics through the Problems API while Isolated Projects moves toward stable.

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.
