What is ROOT?
ROOT is shipping the pieces of its long-promised v7 inside the v6 release line
ROOT maintains an unusual number of parallel branches — patches for 6.26, 6.28, 6.30, 6.32, 6.36 and 6.38 all landed within weeks of each other in June 2026 — because CERN experiments pin to versions for years at a time. The 6.40 LTS released in May is where the actual work is: an opt-out from automatic object registration, experimental multithreaded histograms, a new RFile interface, an libcurl-based HTTP I/O layer with S3 support, and a rebuilt ML data loader. June's patch wave is the routine consequence, closing out the 6.26 and 6.38 series while fixing the first regressions in 6.40.
What is Fulcrum?
Fulcrum is consolidating its whole mapping stack on Esri, and retiring Google Maps to finish it.
Fulcrum ships weekly web release notes alongside separate iOS and Android builds, and nearly all of the recent work is mapping. The ArcGIS SDK moved to 300.0.0 on mobile and the map engine picked up current ArcGIS and deck.gl versions on web, while a run of fixes addressed offline layer styling, basemap loading and attachment downloads on poor connections. On-device machine learning inference dropped ONNX for a new format, with labels now read from an uploaded labels.txt file.

◆ Current state
ROOT maintains an unusual number of parallel branches — patches for 6.26, 6.28, 6.30, 6.32, 6.36 and 6.38 all landed within weeks of each other in June 2026 — because CERN experiments pin to versions for years at a time. The 6.40 LTS released in May is where the actual work is: an opt-out from automatic object registration, experimental multithreaded histograms, a new RFile interface, an libcurl-based HTTP I/O layer with S3 support, and a rebuilt ML data loader. June's patch wave is the routine consequence, closing out the 6.26 and 6.38 series while fixing the first regressions in 6.40.
◆ Where it's heading
The ROOT 7 redesign is arriving piecemeal under ROOT::Experimental rather than as a version bump: RNTuple replacing TTree, RDataFrame replacing TTree::Draw, RFile replacing TFile, and now the ability to switch off the global-directory ownership model that has defined ROOT's ergonomics for decades. The team is easing migration with documentation rather than deprecation — 6.40 ships a TTree::Draw-to-RDataFrame translation guide instead of a removal notice. Build weight is being cut in the same pass, with bundled builtin packages reduced roughly fourfold in favour of system libraries.
◆ Prediction
Expect further 6.40.x patches through the year as experiments migrate onto the LTS, concentrated in RNTuple and the new histogram paths where the code is youngest. The experimental namespace is the thing to watch: features that stabilize there are the clearest available signal of what a ROOT 7 would actually contain.
Fulcrum
6.3ANALYTICS
Fulcrum is consolidating its whole mapping stack on Esri, and retiring Google Maps to finish it.
◆ Current state
Fulcrum ships weekly web release notes alongside separate iOS and Android builds, and nearly all of the recent work is mapping. The ArcGIS SDK moved to 300.0.0 on mobile and the map engine picked up current ArcGIS and deck.gl versions on web, while a run of fixes addressed offline layer styling, basemap loading and attachment downloads on poor connections. On-device machine learning inference dropped ONNX for a new format, with labels now read from an uploaded labels.txt file.
◆ Where it's heading
The mapping stack is converging on Esri across every client, and the announced September 1 retirement of the legacy Google Maps engine makes that explicit. Esri Maps has absorbed Google's satellite, hybrid and street basemaps, and the GIS capabilities Fulcrum keeps investing in — snapping, ArcGIS Feature Service connectivity, offline basemaps, GPS tracks, the redesigned location editor — only exist on that engine. Everything else in the feed is stabilization on the same surface, which is what a team does when it is preparing to move every remaining customer onto one path.
◆ Prediction
Expect migration reminders and switching guidance for organizations still defaulting to Google Maps as September 1 approaches, and MMPK layers to leave Early Access once the engine consolidation is complete.
