A side-by-side editorial comparison of SimInf and wasserportal — release velocity, themes, recent moves, and the top alternatives to consider.
SimInf 10.0 turns an epidemic simulator into a tool that fits models to real time series
SimInf simulates stochastic disease spread over networks of nodes, with a model parser that compiles user-specified transitions to C. Version 10.0.0 was a deliberate major break: the SimInf_pfilter S4 class and the bootstrap filtering interface were redesigned, a replicates slot was added to SimInf_model, a multi-particle variant of the split-step solver arrived, and the package gained Particle Markov Chain Monte Carlo fitting against observed time series. The follow-up 10.1.0 is a single zero-length memcpy fix found by CRAN's M1 checks.
A Berlin groundwater scraper grew a full IoT publishing pipeline in two days.
wasserportal scrapes groundwater and surface water monitoring data from Wasserportal Berlin — station metadata, water levels, quality series. For its first four years that was the whole product, with releases tracking the portal's own churn: a new API version in 2023, new three-letter variable codes, and a 2026 fix decoding pages as windows-1252 because the server declares UTF-8 but emits Latin-1. In June 2026 it added a ThingsBoard integration, then extended it to self-hosted instances two days later.

The package has been moving from simulation toward inference for several releases. The 9.x line built the input side — utilities for cleaning raw individual event data, variables and enumeration constants in the model parser — and 10.0.0 closed the loop by making the simulator fittable to data through PMCMC. The version number was incremented precisely because that required breaking the particle filter interface.
Fitting machinery this new usually needs a second pass on usability, so the next releases most likely focus on diagnostics and documentation around PMCMC rather than on the simulation core, which has been stable across the whole 9.x and 10.x history.

In June 2026 it added a ThingsBoard integration, then extended it to self-hosted instances two days later.
The package is repositioning from a data-access library into the first half of a monitoring pipeline. 0.6.0 shipped push helpers, device discovery and cleanup, an importable dashboard and a GitHub Actions workflow; 0.7.0 immediately generalised the authentication so it works against self-hosted Community Edition rather than only the Cloud tier, and lifted the push from a five-station demo to the entire groundwater archive. The hardening detail in 0.7.0 — retries on 5xx, warnings when only one of two credentials is set — reads like a maintainer who has run this against a real deployment.
The obvious next step is extending the ThingsBoard path to the surface water stations, which the package has flagged as under-supported since 0.1.0. The entries show no other direction under construction.
