ZoneMinder vs OctoPrint: at a glance
What is ZoneMinder?
ZoneMinder 1.38 finally split capturing from analysing — and added roles to a system that had none.
ZoneMinder runs two lines in parallel. The 1.38 series, opened in February, brought role-based access control, WebRTC, Go2RTC and RTSP2Web streaming with hardware acceleration, a redesigned monitor model splitting Capturing, Analysing and Recording into separate settings, ONVIF events, MQTT and event tagging. The legacy 1.36 branch is still receiving fixes, including a stored SQL injection through event name and cause fields. The 1.38.1 release replaced four vendor-specific ONVIF implementations with a single control module.
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.

ZoneMinder
0.0INFRA · APIS
ZoneMinder 1.38 finally split capturing from analysing — and added roles to a system that had none.
◆ Current state
ZoneMinder runs two lines in parallel. The 1.38 series, opened in February, brought role-based access control, WebRTC, Go2RTC and RTSP2Web streaming with hardware acceleration, a redesigned monitor model splitting Capturing, Analysing and Recording into separate settings, ONVIF events, MQTT and event tagging. The legacy 1.36 branch is still receiving fixes, including a stored SQL injection through event name and cause fields. The 1.38.1 release replaced four vendor-specific ONVIF implementations with a single control module.
◆ Where it's heading
The project is consolidating a decade of accumulated special cases: four ONVIF implementations become one, monitor function modes become independent toggles, and streaming moves onto standard components rather than bespoke paths. Meanwhile 1.36 keeps being patched for security and build compatibility, which means a substantial install base has not moved. Release engineering itself is visibly strained — 1.38.2 was abandoned mid-flight over a Debian packaging conflict.
◆ Prediction
Expect 1.38 patch releases to keep folding in security and memory-safety fixes while the 1.36 branch receives only vulnerability backports until it is retired. Whether the new streaming stack becomes the default rather than an option is not settled by these entries.
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.
