micrOS 3.0 - Standalone

Release Notes

micrOS 3.0 focuses on core stability, modern communication paths, a cleaner filesystem layout, and better package/runtime maintainability.

DISCUSSIONS

Core System Improvements

1. Async SSL/TLS integration

• Added async SSL/TLS support in the core HTTP client path.
• urequests was redesigned for async REST client usage.
• Requires MicroPython 1.22+.
• Enables improved integrations such as:
  • LM_telegram notification flows
  • listener/server-side chatbot communication patterns

2. ESP-NOW integration in InterCon

• Added ESP-NOW peer-to-peer communication support to InterCon.
• Improved multi-command handling for the same target device with better session ID handling.
• Provides a lower-latency fallback/alternative path for device-to-device messaging.

3. New InterCon command syntax

• Added command-level remote execution syntax:
  • rgb toggle >>RingLight.local
• This replaces the older verbose form:
  • intercon sendcmd host="RingLight.local" cmd="rgb toggle"
• ESP-NOW is transparently integrated into the new >>target syntax when available on the target.

4. Multi-level project and filesystem structure

• Introduced a structured micrOS filesystem layout with automatic directory creation at boot and over USB.
• New runtime directories:
  • /lib
  • /logs
  • /web
  • /data
  • /config
  • /modules
• Added automatic handling for /source and /precompiled.

Filesystem model:

• Root /
  • core runtime files such as micrOS.py, Config.py, Tasks.py, Shell.py, Web.py, Server.py, and related system files
• /web
  • static web assets: html, js, css, and related files
• /data
  • runtime and persistent application data
  • *.cache
  • *.dat
• /logs
  • *.log
  • *.sys.log
• /config
  • node_config.json
  • offloaded config values such as *.key
• /modules
  • LM_*
  • IO_*
  • mip-compatible layout support via /lib

5. Universal task creation response

• Task creation now uses a unified response format:
  • {taskID: verdict}

6. Proper mip installer support

• Added package installation support for /modules, /lib, and /web.
• Expanded autonomous package management over Wi-Fi / GitHub:
  • pacman install <package-url>
  • pacman uninstall <package-name>
  • pacman upgrade <package-name>
  • pacman ls
  • pacman dirtree

7. Native requirements.txt handling

• Added /config/requirements.txt support using native MicroPython requirements syntax.
• Supported flow:
  • pacman install "requirements.txt"

8. External package ecosystem support

• Added micrOS/packages submodule support for installable micrOS applications.
• Application registry:
  • micrOSPackages
• Added devToolKit rendering support for external package load modules:
  • sfuncman.json
  • sfuncman.html

9. MicroPython uplift to 1.27

• Updated baseline compatibility to MicroPython 1.27.
• Includes fixes for micrOS USB update config restore issues.
• Includes TLS/SSL configuration fixes (sunset-sunrise API)

10. WebEngine mount and alias support

• Added WebEngine mount aliases for /data, /modules, '/logs'.

• Default web root remains /web/<user_data>.

• Added absolute user input path checks in Files.py.

• Improved file server integration:

  • custom /modules listing without .mpy files
  • mount-path write access handling
  • mount-path read and visibility handling

11. @Auth.sudo decorator

• Added @Auth.sudo for protected operations requiring pwd="<password>".
• Supports two modes:
  • always require password
  • require only when force=True
• Intended for sensitive operations such as:
  • pacman rm
  • pacman rmdir
  • pacman uninstall
  • forced upgrade flows

12. WebEngine finite state machine redesign

• Reworked WebEngine protocol parsing around a robust finite state machine.
• Decoupled transport handling from protocol parsing.
• Always forwards response headers to load module callback functions.
• Added bounded memory behavior and configurable memory profiles.
• Improved WebUI stability with better socket handling.

13. Boot flow and request-path optimization

• Improved generic boot flow behavior.
• Refined request handling and TLS/HTTPS behavior for better reliability.

Highlights

• Async TLS support for modern integrations
• Stronger InterCon with ESP-NOW support
• Cleaner and more scalable filesystem structure
• Better package management and mip compatibility
• More robust WebEngine with tighter memory handling
• Updated MicroPython baseline to 1.27

micrOS 2.6

WebUI - webserver and interface improvements

• Webserver file response (html, js, css)
  • improved index.html
  • new dashboard.html
  • refactors: uapi.js, udashboard.js, uwidgets.js, uwidgets_pro.js
  • common ustype.css
• Finalized Load module interfaces:
  • microIO.py
  • Common.py
  • Types.py for frontend generation - dashboard webapp
• Simulator improvements
• Generic micrOS core improvements

  Full Changelog: v2.0.0-0...v2.6.0-0

micrOS 2.0 LTS

Micropython base: 1.21.x

micrOS 2.0 LTS

	Core:
                - ShellCli - high performance low level communication and configuration interface
		- WebCli (http server with endpoints: / and /rest and /<custom>)
		- Full async as technically possible (WebCLI, ShelCLI, TaskManager (LM), InterCon)
			- rest (urequests) stays sync module (https limitation with async.) 
		- Extensive testing and quality checks (system tests, pylint) 
		Web Frontends:
			- index.html
                - Common.py interface for LoadModule-s documentation
	
	Load Module:
		- Camera support (LM_OV2640.py)
