What is OpenObserve?

After its largest release, OpenObserve is patching the seams.

v0.92.0 landed on 7 August with 836 commits and three new product surfaces - synthetic monitoring, Workflows v1, and an expanded AI observability set - after a long RC series. The two releases since are small: v0.92.1 fixed alert HAVING clause typing and put the MCP server setup page on the OSS build, and v0.92.2 adds a compactor delay setting and backports an MCP 404 fix for deployments running under a base URI. The 0.91 line is still receiving its own backports.

What is tidyposterior?

A finished Bayesian model-comparison package in pure maintenance mode

tidyposterior compares model performance using Bayesian resampling analysis, and it reached its intended shape years ago. Every release since 1.0.0 has been maintenance: a broken test under R-devel, a maintainer email change, and most recently compatibility with an upcoming ggplot2 release plus the base-pipe transition. The substantive API decisions — autoplot() over ggplot() methods, tibble returns from contrast_models() — were settled in the 0.x series.

OpenObserve vs tidyposterior: editorial side-by-side

6.3

After its largest release, OpenObserve is patching the seams.

◆ Current state

v0.92.0 landed on 7 August with 836 commits and three new product surfaces - synthetic monitoring, Workflows v1, and an expanded AI observability set - after a long RC series. The two releases since are small: v0.92.1 fixed alert HAVING clause typing and put the MCP server setup page on the OSS build, and v0.92.2 adds a compactor delay setting and backports an MCP 404 fix for deployments running under a base URI. The 0.91 line is still receiving its own backports.

◆ Where it's heading

OpenObserve is trying to become the whole monitoring stack rather than the storage layer under one. Synthetic checks, incident workflows, and SLO measurement each replace a separate tool, and incident ingestion from external alert sources hedges the migration path for teams that cannot switch all at once. The MCP work running alongside - open sourced, then given a setup page in the OSS build, then fixed for base-URI deployments - shows the same data being aimed at agent clients rather than dashboards.

◆ Prediction

The post-GA patches are still landing on the new surfaces, so expect another 0.92.x before feature work resumes - most likely hardening synthetic monitoring and Workflows, which are the two least-exercised additions.

A finished Bayesian model-comparison package in pure maintenance mode

◆ Current state

tidyposterior compares model performance using Bayesian resampling analysis, and it reached its intended shape years ago. Every release since 1.0.0 has been maintenance: a broken test under R-devel, a maintainer email change, and most recently compatibility with an upcoming ggplot2 release plus the base-pipe transition. The substantive API decisions — autoplot() over ggplot() methods, tibble returns from contrast_models() — were settled in the 0.x series.

◆ Where it's heading

The package tracks its dependencies rather than developing on its own line, and the dependencies do the moving: rstanarm API changes, dplyr 1.0.0, testthat 3e, ggplot2. Its integration surface widened once, when perf_mod() gained methods for tuning parameter objects from tune, finetune, and workflowsets, and has been stable since. This is what a completed package in an active ecosystem looks like.

◆ Prediction

Expect the next release to be triggered by an upstream change rather than by anything tidyposterior wants to do differently.
