What is Merge?
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
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.
Merge vs tealeaves: editorial side-by-side
Merge
6.3INFRA · APIS
Merge is turning its weekly integration digest into an agent control plane — the news is always at the bottom.
◆ Current state
Merge publishes one dated digest a week, and the structure is consistent: unified Accounting, ATS, CRM, File Storage and HRIS reliability work up top, then Agent Handler and Gateway at the end, where the directional changes live. The feed now also carries per-product breakout entries (Gateway, Unified, Agent Handler) that restate the same week's items in more detail rather than adding new ones. The Agent Handler catalog carries hundreds of generic MCP connectors alongside Merge's own, on shared authentication and policy, and Gateway has been accumulating model coverage, routing controls and guardrails over the same period.
◆ Where it's heading
The through-line is that Merge is repositioning from data plumbing to the layer agents pass through. Each week adds either reach (more connectors, more tools per connector, more models) or control (guardrails, per-project policy, access configuration). This window is reach-and-efficiency: the GitHub connector expanded to 145 tools, Outlook payloads were cut substantially, and Gateway guardrails became configurable per project rather than per account.
◆ Prediction
Expect the per-project granularity applied to guardrails to spread to the rest of Gateway's controls, and the connector catalog to keep absorbing hosted third-party MCP servers the way Axiom was added.
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.
