Rancher vs tealeaves
A side-by-side editorial comparison of Rancher and tealeaves — release velocity, themes, recent moves, and the top alternatives to consider.
Rancher vs tealeaves: at a glance
What is Rancher?
Rancher's public feed is a build-tag stream: three branches bumped the same Go image on one afternoon
Rancher's public release feed is a tag stream rather than a changelog. The newest activity is three alpha tags cut within eight minutes on August 19 across the 2.12, 2.13 and 2.14 branches — two bumping the same SUSE Go base image to 1.25.13 via a bot, one pulling in a Fleet release candidate. The two maintenance releases before them, 2.12.12 and 2.11.16, each carry a single line pointing readers to the Prime documentation for the actual notes.
What is tealeaves?
A leaf-temperature model that finished its job in 2020 and has stayed finished
tealeaves solves for leaf temperature from an energy balance, using explicit units to keep parameters consistent and modelling lower and upper leaf surfaces separately so sensible and latent heat loss are computed for each. The package reached its current form in 2020 across versions 1.0.2 to 1.0.5, which added direct or functional sky temperature, dplyr 1.0.0 compatibility, and fixes to a parameter-crossing bug that the new sky temperature function had introduced. The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.

Rancher's public feed is a build-tag stream: three branches bumped the same Go image on one afternoon
◆ Current state
Rancher's public release feed is a tag stream rather than a changelog. The newest activity is three alpha tags cut within eight minutes on August 19 across the 2.12, 2.13 and 2.14 branches — two bumping the same SUSE Go base image to 1.25.13 via a bot, one pulling in a Fleet release candidate. The two maintenance releases before them, 2.12.12 and 2.11.16, each carry a single line pointing readers to the Prime documentation for the actual notes.
◆ Where it's heading
Four branches are now tagged in parallel, with 2.11 and 2.12 taking maintenance while 2.15 works through release candidates. The August alpha cluster is automated dependency traffic, not product work, and because notes for the supported branches live behind the Prime docs this feed will keep showing cadence without content. The only readable signals stay structural: which branches get tagged, and how far the 2.15 candidates have progressed.
◆ Prediction
The 2.15 line still looks closest to shipping, so the next visible move is a 2.15.0 general release tag — again with its notes pointing to Prime documentation rather than appearing here.
tealeaves
0.0INFRA · APIS
A leaf-temperature model that finished its job in 2020 and has stayed finished
◆ Current state
tealeaves solves for leaf temperature from an energy balance, using explicit units to keep parameters consistent and modelling lower and upper leaf surfaces separately so sensible and latent heat loss are computed for each. The package reached its current form in 2020 across versions 1.0.2 to 1.0.5, which added direct or functional sky temperature, dplyr 1.0.0 compatibility, and fixes to a parameter-crossing bug that the new sky temperature function had introduced. The only release since, v1.0.6 in July 2022, corrects a name in the citation file, stops parallel evaluation in a vignette and fixes README links.
◆ Where it's heading
This is finished scientific software. The arc runs from a 1.0.0 that already described the full model, through a usability decision in 1.0.1 to accept unitless values and assign units rather than demand them, to a 2020 cluster of compatibility and correctness work around publication. Nothing since has touched the model, and the 2022 release is pure paperwork. Its most instructive entry remains 1.0.5, where a new feature silently produced incorrect parameter crossing and the fix arrived with tests to pin the behaviour.
◆ Prediction
Expect nothing unless a dependency or CRAN check forces a release; on this record any such release will be documentation and packaging rather than a change to the energy balance.
