CoolProp vs uproot5: at a glance
What is CoolProp?
CoolProp 8.0 bought sub-microsecond property lookups — and shipped a desktop app alongside it.
CoolProp released 8.0.0 in June 2026 after a long 7.x period, and paired it the same day with the first signed release of a Desktop GUI that had spent two months in unsigned alphas. The library release is dense: an SVD-compressed tabular backend giving sub-microsecond per-probe evaluation in the batched path, mass-basis vapor quality across HEOS and REFPROP, Chebyshev superancillaries for the SRK and Peng-Robinson cubics, a large fluid and mixture library expansion including the 2026 ASHRAE Standard 34 blends, and thread-safety work.
What is uproot5?
Uproot quietly made RNTuple the default write format — filed under 'chore'.
Uproot ships small, frequent 5.7.x releases in which the RNTuple work dominates and is often buried below the feature list. Since switching the default write format to RNTuple in 5.7.0, the releases have been about making that path complete: entry bounds and report=True for RNTuple.iterate, GPU interpretation of RNTuple data with nvCOMP decompression, support for the v1.0.1.0 format, and the library kwarg finished. Two of the six releases in this window list no new features at all.

CoolProp

CoolProp 8.0 bought sub-microsecond property lookups — and shipped a desktop app alongside it.
◆ Current state
CoolProp released 8.0.0 in June 2026 after a long 7.x period, and paired it the same day with the first signed release of a Desktop GUI that had spent two months in unsigned alphas. The library release is dense: an SVD-compressed tabular backend giving sub-microsecond per-probe evaluation in the batched path, mass-basis vapor quality across HEOS and REFPROP, Chebyshev superancillaries for the SRK and Peng-Robinson cubics, a large fluid and mixture library expansion including the 2026 ASHRAE Standard 34 blends, and thread-safety work.
◆ Where it's heading
The project is moving on two fronts that reinforce each other: making evaluation fast enough to sit inside simulation inner loops, and putting a real application in front of engineers who previously had to write Python to use it. The new tabular backend being off by default in PropsSI says the maintainers are treating accuracy conservatively while the fast path proves out. The GUI's progression from unsigned alpha to notarized and SignPath-signed release in two months is the clearest sign it is meant as a product, not a demo.
◆ Prediction
Expect the SVDSBTL backend's default-off flag to be revisited once conformance data accumulates, and the GUI to continue on its own version line now that the signing and auto-update pipeline is live.
uproot5
0.0DEVOPS
Uproot quietly made RNTuple the default write format — filed under 'chore'.
◆ Current state
Uproot ships small, frequent 5.7.x releases in which the RNTuple work dominates and is often buried below the feature list. Since switching the default write format to RNTuple in 5.7.0, the releases have been about making that path complete: entry bounds and report=True for RNTuple.iterate, GPU interpretation of RNTuple data with nvCOMP decompression, support for the v1.0.1.0 format, and the library kwarg finished. Two of the six releases in this window list no new features at all.
◆ Where it's heading
This is a migration project wearing patch-release clothing. The direction is that RNTuple, ROOT's newer columnar format, becomes what Uproot writes and reads by default, with the older TTree path maintained rather than developed. The GPU decompression work points further out: reading physics data straight into accelerator memory rather than staging it through the CPU. Expect the remaining gaps to keep surfacing as bug fixes in the RNTuple path as more of the field writes in the new format.
◆ Prediction
Continued 5.7.x patches closing RNTuple feature parity with TTree, with the GPU and nvCOMP path the most likely area to gain rather than just get fixed.
