CoolProp vs stringr: 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 stringr?
stringr keeps trading convenient guesses for predictable errors.
stringr is at 1.6.0, which preserved names across the function set, made str_like() case sensitive to match the SQL operator it is named after, and changed str_replace_all() so a replacement function receives one vector of all values — faster, and breaking for anyone relying on the old call pattern. It also added str_ilike() and the programming-case helpers str_to_camel(), str_to_snake() and str_to_kebab().

◆ 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.

stringr keeps trading convenient guesses for predictable errors.
◆ Current state
stringr is at 1.6.0, which preserved names across the function set, made str_like() case sensitive to match the SQL operator it is named after, and changed str_replace_all() so a replacement function receives one vector of all values — faster, and breaking for anyone relying on the old call pattern. It also added str_ilike() and the programming-case helpers str_to_camel(), str_to_snake() and str_to_kebab().
◆ Where it's heading
Every substantial release in this window removes an accommodation. 1.5.0 enforced tidyverse recycling rules so only length-1 vectors recycle, turned many warnings into errors, and made str_detect() with an empty string an error rather than a silent TRUE. 1.6.0 continues that: the functions guess less and reject more, and each round trades a convenience for a predictable failure.
◆ Prediction
With str_like(ignore_case) newly deprecated, the next release most likely completes that removal and continues aligning behaviour with SQL string operators rather than adding a new function family.
