Terragrunt vs OctoPrint: at a glance
What is Terragrunt?
Terragrunt graduated six experiments at once and has spent three candidates stabilising them
Terragrunt is running the v1.1.0 release-candidate cycle, now at rc3. The first candidate completed six experiments simultaneously — stack-dependencies, a content-addressable store, a catalog redesign, mark-many-as-read, opt-out-auth and DAG queue display. The two candidates since have added only bug fixes for those features plus improvements to how releases are published and verified.
What is OctoPrint?
OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.
The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

Terragrunt graduated six experiments at once and has spent three candidates stabilising them
◆ Current state
Terragrunt is running the v1.1.0 release-candidate cycle, now at rc3. The first candidate completed six experiments simultaneously — stack-dependencies, a content-addressable store, a catalog redesign, mark-many-as-read, opt-out-auth and DAG queue display. The two candidates since have added only bug fixes for those features plus improvements to how releases are published and verified.
◆ Where it's heading
The experiment-graduation model is doing what it is supposed to: features developed behind flags land together in one minor, and the candidate cycle is purely stabilisation. The release-publishing and verification work appearing in rc2 suggests supply-chain provenance is being treated as release-blocking rather than as a follow-up.
◆ Prediction
With three candidates carrying identical feature lists, v1.1.0 final is the likely next release, followed by a fresh batch of experiments opening for v1.2.
OctoPrint
2.5INFRA · APIS
OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.
◆ Current state
The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.
◆ Where it's heading
Serial is being demoted from the way OctoPrint talks to a printer to one implementation of a connector interface, which is the structural precondition for supporting printers that speak something else. The cost is deliberate: rc1 removes deprecated APIs, warns that plugins will break, and points users at a recovery page to restart in safe mode. A maintainer running a long public RC cycle on a single-maintainer project is managing that breakage rather than rushing past it.
◆ Prediction
Expect further RCs until the connector migration stops producing reports, with the plugin ecosystem's readiness — not the core code — deciding when 2.0.0 goes stable.
