A side-by-side editorial comparison of CoolProp and Manticore Search — release velocity, themes, recent moves, and the top alternatives to consider.
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.
The 29.0 line is stabilizing in public; 29.1 opens with load-tool work rather than engine work.
Manticore shipped 29.0.3 through 29.0.6 across four days after the 29.0.2 release notes consolidated the sharding work, and has now opened the 29.1 line. The patches are shaped by what 29.0 exposed: internal sort helper columns leaking into LEFT JOIN output, NEAR and proximity distances reset by repeated JSON query fixup, malformed binary-API search counts allocating before validation, and fatal binlog replay errors that failed to name the --replay-flags value an operator needs. The 29.1.0 opener is not engine work at all — it bumps the bundled manticore-load tool and gives it worker init and finalize hooks.

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.
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.
Manticore shipped 29.0.3 through 29.0.6 across four days after the 29.0.2 release notes consolidated the sharding work, and has now opened the 29.1 line. The patches are shaped by what 29.0 exposed: internal sort helper columns leaking into LEFT JOIN output, NEAR and proximity distances reset by repeated JSON query fixup, malformed binary-API search counts allocating before validation, and fatal binlog replay errors that failed to name the --replay-flags value an operator needs. The 29.1.0 opener is not engine work at all — it bumps the bundled manticore-load tool and gives it worker init and finalize hooks.
The pattern after a major line opens is holding: the commit-level train runs at multiple releases a day while the newly exposed surfaces — sharded tables, LEFT JOIN, JSON query parsing — report their edge cases back, each fix arriving with regression coverage attached rather than accumulating into a batch. The 29.0.6 binlog change is a small tell about where the team's attention sits: improving the error text an operator reads at 3am is the kind of fix that only gets prioritised once real clusters are running the new line.
The patch cadence should keep compressing toward the ordinary rhythm as the 29.0 edge cases drain. The next substantive engine item is more likely to come from the columnar and KNN thread than from sharding, which has just had its release.
