What is epiworldR?

epiworldR is a thin R shell whose releases track the C++ simulator underneath it

Almost every release here is a version bump of the underlying epiworld C++ library, wrapped and pushed to CRAN. The substantive R-side work is narrow and consistent: exposing simulation outputs that were already computed but not reachable from R — outbreak size, active cases, hospitalizations and their savers. The newest release addresses an AddressSanitizer finding, which is the kind of thing CRAN checks surface on a compiled package.

What is OpenObserve?

After the 836-commit 0.92 release, OpenObserve is quietly moving its MCP server into the free tier

OpenObserve is in the settle-down phase after v0.92.0, the largest release the project has shipped, which added synthetic monitoring, Workflows v1, an expanded AI observability set, per-group and per-series alerting with SLOs, and moved Vortex and the MCP server into open source. The v0.92.1 patch that followed is small but pointed: the MCP Server setup page now renders on the OSS build, and an alerts bug where the HAVING clause was typed from the column rather than the aggregate is fixed. The 0.91 line continues to receive backported fixes in parallel.

epiworldR is a thin R shell whose releases track the C++ simulator underneath it

◆ Current state

Almost every release here is a version bump of the underlying epiworld C++ library, wrapped and pushed to CRAN. The substantive R-side work is narrow and consistent: exposing simulation outputs that were already computed but not reachable from R — outbreak size, active cases, hospitalizations and their savers. The newest release addresses an AddressSanitizer finding, which is the kind of thing CRAN checks surface on a compiled package.

◆ Where it's heading

The R package's job is staying current with the simulator and satisfying CRAN, not evolving its own interface. What direction it has shows in which model outputs get exposed next, and in a steady tidy-up of the build — the custom configure script was dropped in favour of R's built-in C++17 and OpenMP settings, and test coverage has been filled in across several releases with automated assistance.

◆ Prediction

Expect the next release to track another epiworld version bump, with any R-side addition most likely being one more exposed metric or saver, following the pattern of get_hospitalizations and get_outbreak_size.

After the 836-commit 0.92 release, OpenObserve is quietly moving its MCP server into the free tier

◆ Current state

OpenObserve is in the settle-down phase after v0.92.0, the largest release the project has shipped, which added synthetic monitoring, Workflows v1, an expanded AI observability set, per-group and per-series alerting with SLOs, and moved Vortex and the MCP server into open source. The v0.92.1 patch that followed is small but pointed: the MCP Server setup page now renders on the OSS build, and an alerts bug where the HAVING clause was typed from the column rather than the aggregate is fixed. The 0.91 line continues to receive backported fixes in parallel.

◆ Where it's heading

The MCP thread is the one to watch. Open-sourcing the server in 0.92.0 was the architectural move; serving its setup page on the OSS build a week later is what makes it reachable without an enterprise license. That points at agent clients as a first-class consumption path rather than an enterprise upsell, which is a different distribution bet than the synthetic-monitoring and Workflows surfaces that headlined the same release. Everything else in this window is stabilization — RC backports, memtable rotation, RBAC migrations — consistent with a project digesting a release that spanned two repositories and a large-scale crate reorganization.

◆ Prediction

Expect a run of 0.92.x patches concentrated on the three new surfaces, since synthetic monitoring, Workflows and eval scheduling all shipped at once with limited production exposure. The alerts fix suggests the aggregation path is a likely source of further corrections.
