What is Grafana Mimir?

Mimir's feed is a weekly Helm bot, with the 3.2 candidate the only real release in months

The visible cadence is an automated weekly Helm chart release opened by a bot with a two-line body, now at 6.3.0-weekly.408. The only substantive entry in the window is the 3.2.0 release candidate from early August, which carried query engine work and native histogram support.

What is regfusionr?

Registration fusion mapping goes bidirectional, and a vertex-indexing bug that silently returned wrong coordinates is fixed

regfusionr maps coordinates between volumetric brain templates (MNI152, Colin27) and the fsaverage surface. After four dormant years it returned in July 2026 with a release that fixes a coordinate-indexing bug, unblocks a previously disabled function, and completes the template-by-method matrix so all four combinations answer point queries. It also breaks compatibility by switching to the standard FREESURFER_HOME environment variable.

Mimir's feed is a weekly Helm bot, with the 3.2 candidate the only real release in months

◆ Current state

The visible cadence is an automated weekly Helm chart release opened by a bot with a two-line body, now at 6.3.0-weekly.408. The only substantive entry in the window is the 3.2.0 release candidate from early August, which carried query engine work and native histogram support.

◆ Where it's heading

Packaging and the engine move on separate clocks: the chart ships weekly regardless of whether anything changed underneath, while Mimir itself cuts a minor roughly monthly. The weekly stream tells you nothing about direction and will keep dominating the feed by volume.

◆ Prediction

The chart line moving from 6.2.0-weekly to 6.3.0-weekly points at a 6.3.0 chart release carrying Mimir 3.2 once the candidate goes final.

Registration fusion mapping goes bidirectional, and a vertex-indexing bug that silently returned wrong coordinates is fixed

◆ Current state

regfusionr maps coordinates between volumetric brain templates (MNI152, Colin27) and the fsaverage surface. After four dormant years it returned in July 2026 with a release that fixes a coordinate-indexing bug, unblocks a previously disabled function, and completes the template-by-method matrix so all four combinations answer point queries. It also breaks compatibility by switching to the standard FREESURFER_HOME environment variable.

◆ Where it's heading

The package moved from a partial implementation to a complete one in a single release. Before this, vol_coords_to_fsaverage returned coordinates indexed by query position rather than by vertex index — results that looked plausible and were wrong — and fsaverage_to_vol was guarded behind a stop(). Both are now resolved, and the new Colin27 and MNI152 convenience functions make the mapping bidirectional. The sibling package haze shipped a maintenance release 56 minutes later, marking this as a coordinated sweep across the maintainer's neuroimaging stack.

◆ Prediction

With the four template-by-method combinations closed and the coordinate bug fixed, the next release is more likely to be CRAN-adjacent packaging or documentation than new mapping capability.
