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.

What is GLAuth?

A small LDAP server that grew OpenTelemetry tracing, embedded plugins and RISC-V builds.

GLAuth's 2.5.0 in April was the substantial release: OpenTelemetry tracing wired through the handler and plugin packages plus otelsql, embedded plugins, RISC-V platform support, StartTLS and LDAPS brought to feature parity, and LDAP paging compatibility when proxying. The two releases since are corrective — rejecting disabled users on all backends during Bind, an arbitrary-password issue, and a release-time plugin compatibility check.

2.5

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.

5.0

A small LDAP server that grew OpenTelemetry tracing, embedded plugins and RISC-V builds.

◆ Current state

GLAuth's 2.5.0 in April was the substantial release: OpenTelemetry tracing wired through the handler and plugin packages plus otelsql, embedded plugins, RISC-V platform support, StartTLS and LDAPS brought to feature parity, and LDAP paging compatibility when proxying. The two releases since are corrective — rejecting disabled users on all backends during Bind, an arbitrary-password issue, and a release-time plugin compatibility check.

◆ Where it's heading

The direction in 2.5.0 is toward being operable in production rather than merely functional: distributed tracing, a config watcher that notices files added to a directory, credentials no longer leaking at INFO log level, and a legacy behaviour mode so existing deployments can upgrade without changing semantics. The patches since suggest the authentication paths are getting scrutiny they had not previously had, with disabled-user handling inconsistent across backends until 2.5.1 fixed it.

◆ Prediction

Expect the 2.5 line to keep taking small authentication-correctness fixes, with the embedded plugin mechanism and the release-time compatibility check pointing toward more attention on how third-party backends are built and shipped.
