###### ⚠️ Important note on release candidates This is a **R**elease **C**andidate of OctoPrint. It is not a stable release: severe bugs can occur, and they can be bad enough that they make a manual downgrade to an earlier version necessary - maybe even from the command line. You should be comfortable with and capable of possibly having to do this before installing an RC. ###### 🔁 Feedback on this RC Please provide *general* feedback on this RC [in this ticket](https://github.com/OctoPrint/OctoPrint/issues/5403). An "All is working fine" is valuable feedback as well because it tells me people are actually testing this RC and just not finding problems with it. **If you run into any obvious bugs, please follow ["How to file a bug report"](https://github.com/OctoPrint/OctoPrint/blob/master/CONTRIBUTING.md#how-to-file-a-bug-report)** - I need logs and reproduction steps to fix issues, not just the information that something doesn't work. Thanks! ###### Things to take a closer look at For this RC, these things should get a closer look while testing, if possible: 1. proper behaviour when using the included web interface as well as any third party clients at your disposal 2. printing via a serial connection 3. managing files on your printer's storage via a serial connection 4. blocklisted serial ports and/or baud rates are properly migrated to the serial connector (one per line, *not* comma-separated) 5. if your printer's disconnected state happens to be "after error", please report back on which connector you used and what the reported error is 6. if you have a Klipper/Moonraker based printer available: can you use it through OctoPrint when you install the [Moonraker Connector](https://github.com/OctoPrint/OctoPrint-MoonrakerConnector)? 7. if you have a Bambu based printer available: can you use it through OctoPrint when you install the [Bambu Connector](https://github.com/OctoPrint/OctoPrint-BambuConnector)? ###### ✋ Heads-ups [The heads-ups from 2.0.0rc1 still apply!](https://github.com/OctoPrint/OctoPrint/releases/tag/2.0.0rc1) ###### ✨ Improvements ###### Core - [#5385](https://github.com/OctoPrint/OctoPrint/pull/5385): Add migration for terminal filters to new filter prefixes. Also improve migration guide accordingly. ###### Core UI - Add option to the sidebar file manager's menu to (recursively) refresh the current storage's & path's thumbnails (if supported). ###### Healthcheck Plugin - Add health check hint for unusable `gcode_thumbnail_tool` with link to [the FAQ entry](https://community.octoprint.org/t/octoprint-tells-me-that-the-gcode-thumbnail-tool-is-unavailable/66368). ###### Software Update Plugin - Add support for `forgejo_release` and `forgejo_commit` version check types, which enable version checks against [Forgejo](https://forgejo.org/) code forges such as [Codeberg](https://codeberg.org/). For Codeberg specifically, there's also `codeberg_release` and `codeberg_commit` which internally gets remapped to `forgejo_*` with the correct `forge` parameter. ###### Docs - Add more examples to the migration guide and deprecation list. - Add docs for `octoprint.util.version`. ###### 🐛 Bug fixes ###### Core - [#5377](https://github.com/OctoPrint/OctoPrint/issues/5377) (regression): Fix evaluation of print parameter on upload API. - [#5379](https://github.com/OctoPrint/OctoPrint/pull/5379) (regression): Fix deselection of current print job not working. - [#5380](https://github.com/OctoPrint/OctoPrint/pull/5380) (regression): Allow `None` filament weight in `/api/job` response. - [#5390](https://github.com/OctoPrint/OctoPrint/issues/ _[Truncated at 4000 characters — full notes: https://github.com/OctoPrint/OctoPrint/releases/tag/2.0.0rc2]_
