# OctoPrint Changelog

## 1.2.2 (2015-06-30)

### Bug Fixes

* Fixed an admin-only security issue introduced in 1.2.0, updating is strongly advised.

([Commits](https://github.com/foosel/OctoPrint/compare/1.2.1...1.2.2))

## 1.2.1 (2015-06-30)

### Improvements

* More flexibility when interpreting compatibility data from plugin repository. If compatibility information is provided
  only as a version number it's prefixed with `>=` for the check (so stating a compatibility of only
  `1.2.0` will now make the plugin compatible to OctoPrint 1.2.0+, not only 1.2.0). Alternatively the compatibility
  information may now contain stuff like `>=1.2,<1.3` in which case the plugin will only be shown as compatible
  to OctoPrint versions 1.2.0 and up but not 1.3.0 or anything above that. See also
  [the requirement specification format of the `pkg_resources` package](https://pythonhosted.org/setuptools/pkg_resources.html#requirements-parsing).
* Only print the commands of configured event handlers to the log when a new `debug` flag is present in the config
  (see [the docs](http://docs.octoprint.org/en/master/configuration/config_yaml.html#events)). Reduces risk of disclosing sensitive data when sharing log files.

### Bug Fixes

* [#956](https://github.com/foosel/OctoPrint/issues/956) - Fixed server crash when trying to configure a default
  slicing profile for a still unconfigured slicer.
* [#957](https://github.com/foosel/OctoPrint/issues/957) - Increased maximum allowed body size for plugin archive uploads.
* Bugs without tickets:
  * Clean exit on `SIGTERM`, calling the shutdown functions provided by plugins.
  * Don't disconnect on `volume.init` errors from the firmware.
  * `touch` uploaded files on local file storage to ensure proper "uploaded date" even for files that are just moved
    from other locations of the file system (e.g. when being added from the `watched` folder).

([Commits](https://github.com/foosel/OctoPrint/compare/1.2.0...1.2.1))

## 1.2.0 (2015-06-25)

### Note for Upgraders

  * The [Cura integration](https://github.com/daid/Cura) has changed in such a way that OctoPrint now calls the
    [CuraEngine](https://github.com/Ultimaker/CuraEngine) directly instead of depending on the full Cura installation. See
    [the wiki](https://github.com/foosel/OctoPrint/wiki/Plugin:-Cura) for instructions on how to change your setup to
    accommodate the new integration.

### New Features

* OctoPrint now has a [plugin system](http://docs.octoprint.org/en/master/plugins/index.html) which allows extending its
  core functionality.
  * Plugins may be installed through the new and bundled [Plugin Manager Plugin](https://github.com/foosel/OctoPrint/wiki/Plugin:-Plugin-Manager)
    available in OctoPrint's settings. This Plugin Manager also allows browsing and easy installation of plugins
    registered on the official [OctoPrint Plugin Repository](http://plugins.octoprint.org).
  * For interested developers there is a [tutorial available in the documentation](http://docs.octoprint.org/en/master/plugins/gettingstarted.html)
    and also a [cookiecutter template](https://github.com/OctoPrint/cookiecutter-octoprint-plugin) to quickly bootstrap
    new plugins.
* Added internationalization of UI. Translations of OctoPrint are being crowd sourced via [Transifex](https://www.transifex.com/projects/p/octoprint/).
  Language Packs for both the core application as well as installed plugins can be uploaded through a new management
  dialog in Settings > Appearance > Language Packs. A translation into German is included, further language packs
  will soon be made available.
* Printer Profiles: Printer properties like print volume, extruder offsets etc are now managed via Printer Profiles. A
  connection to a printer will always have a printer profile associated.
* File management now supports STL files as first class citizens (including UI adjustments to allow management of
  uploaded STL files including removal and reslicing) and also allows folders (not yet supported by UI). STL files
  can be downloaded like GCODE files.
* Slicing has been greatly improved:
  * It now allows for a definition of slicing profiles to use for slicing plus overrides which can be defined per slicing
    job (defining overrides is not yet part of the UI but it's on the roadmap).
  * A new slicing dialog has been added which allows (re-)slicing uploaded STL files (which are now displayed in the file list
    as well). The slicing profile and printer profile to use can be specified here as well as the file name to which to
    slice to and the action to take after slicing has been completed (none, selecting the sliced GCODE for printing or
    starting to print it directly)
  * The slicing API allows positioning the model to slice on the print bed (Note: this is not yet available in the UI).
  * Slicers themselves are integrated into the system via ``SlicingPlugins``.
  * Bundled [Cura Plugin](https://github.com/foosel/OctoPrint/wiki/Plugin:-Cura) allows slicing through CuraEngine up
    to and including 15.04. Existing Cura slicing profiles can be imported through the web interface.
* New file list: Pagination is gone, no more (mobile incompatible) pop overs, instead scrollable and with instant
  search
* You can now define a folder (default: `~/.octoprint/watched`) to be watched for newly added GCODE (or -- if slicing
  support is enabled -- STL) files to automatically add.
* New type of API key: [App Session Keys](http://docs.octoprint.org/en/master/api/apps.html) for trusted applications
* OctoPrint now supports `action:...` commands received via debug messages (`// action:...`) from the printer. Currently supported are
  - `action:pause`: Pauses the current job in OctoPrint
  - `action:resume`: Resumes the current job in OctoPrint
  - `action:disconnect`: Disconnects OctoPrint from the printer
  Plugins can add supported commands by [hooking](http://docs.octoprint.org/en/master/plugins/hooks.html) into the
  ``octoprint.comm.protocol.action`` hook
* Mousing over the webcam image in the control tab enables key control mode, allowing you to quickly move the axis of your
  printer with your computer's keyboard ([#610](https://github.com/foosel/OctoPrint/pull/610)):
  - arrow keys: X and Y axes
  - W, S / PageUp, PageDown: Z axes
  - Home: Home X and Y axes
  - End: Home Z axes
  - 1, 2, 3, 4: change step size used (0.1, 1, 10, 100mm)
* Controls for adjusting feed and flow rate factor added to Controls ([#362](https://github.com/foosel/OctoPrint/issues/362))
* Custom controls now also support slider controls
* Custom controls now support a row layout
* Users can now define custom GCODE scripts to run upon starting/pausing/resuming/success/failure of a print or for
  custom controls ([#457](https://github.com/foosel/OctoPrint/issues/457), [#347](https://github.com/foosel/OctoPrint/issues/347))
* Bundled [Discovery Plugin](https://github.com/foosel/OctoPrint/wiki/Plugin:-Discovery) allows discovery of OctoPrint
  instances via SSDP/UPNP and optionally also via ZeroConf/Bonjour/Avahi.
* Bundled [Software Update Plugin](https://github.com/foosel/OctoPrint/wiki/Plugin:-Software-Update) takes care of notifying
  about new OctoPrint releases and also allows updating if configured as such. Plugins may register themselves with the
  update notification and application process through a new hook ["octoprint.plugin.softwareupdate.check_config"](https://github.com/foosel/OctoPrint/wiki/Plugin:-Software-Update#octoprintpluginsoftwareupdatecheck_config).

### Improvements

* Logging is now configurable via config file
* Added last print time to additional GCODE file information
* Better error handling for capture issues during timelapse creation & more robust handling of missing images during
  timelapse creation
* Start counting the layers at 1 instead of 0 in the GCODE viewer
* Upgraded [Font Awesome](https://fortawesome.github.io/Font-Awesome/) to version 3.2.1
* Better error reporting for timelapse rendering and system commands
* Custom control can now be defined so that they show a Confirm dialog with configurable text before executing
  ([#532](https://github.com/foosel/OctoPrint/issues/532) and [#590](https://github.com/foosel/OctoPrint/pull/590))
* Serial communication: Also interpret lines starting with "!!" as errors
* Added deletion of pyc files to the `python setup.py clean` command
* Settings now show a QRCode for the API Key ([#637](https://github.com/foosel/OctoPrint/pull/637))
* Username in UI is no longer enclosed in scare quotes ([#595](https://github.com/foosel/OctoPrint/pull/595))
* Username in login dialog is not automatically capitalized on mobile devices anymore ([#639](https://github.com/foosel/OctoPrint/pull/639))
* "Slicing Done" and "Streaming Done" notifications now have a green background ([#558](https://github.com/foosel/OctoPrint/issues/558))
* Files that are currently in use, be it for slicing, printing or whatever, are now tracked and can not be deleted as
  long as they are in use
* Settings in UI get refreshed when opening settings dialog
* New event "SettingsUpdated"
* "Print time left" is now not displayed until it becomes somewhat stable. Display in web interface now also happens
  in a fuzzy way instead of the format hh:mm:ss, to not suggest a high accuracy anymore where the can't be one. Additionally
  OctoPrint will use data from prior prints to enhance the initial print time estimation.
* Added handler for uncaught exceptions to make sure those get logged, should make the logs even more useful for analysing
  bug reports
* The server now tracks the modification date of the configuration file and reloads it prior to saving the config if
  it has been changed during runtime by external editing, hence no config settings added manually while the server
  was running should be overwritten anymore.
* Display a "Please Reload" overlay when a new server version or a change in installed plugins is detected after a
  reconnect to the server.
* Better handling of errors on the websocket - no more logging of the full stack trace to the log, only a warning
  message for now.
* Daemonized OctoPrint now cleans up its pidfile when receiving a TERM signal ([#711](https://github.com/foosel/OctoPrint/issues/711))
* Added serial types for OpenBSD ([#551](https://github.com/foosel/OctoPrint/pull/551))
* Improved behaviour of terminal:
  * Disabling autoscrolling now also stops cutting off the log while it's enabled, effectively preventing log lines from
    being modified at all ([#735](https://github.com/foosel/OctoPrint/issues/735))
  * Applying filters displays ``[...]`` where lines where removed and doesn't cause scrolling on filtered lines
    anymore ([#286](https://github.com/foosel/OctoPrint/issues/286))
  * Added a link to scroll to the end of the terminal log (useful for when autoscroll is disabled)
  * Added a link to select all current contents of the terminal log for easy copy-pasting
  * Added a display of how many lines are displayed, how many are filtered and how many are available in total
* Frame rate for timelapses can now be configured per timelapse ([#782](https://github.com/foosel/OctoPrint/pull/782))
* Added an option to specify the amount of encoding threads for FFMPEG ([#785](https://github.com/foosel/OctoPrint/pull/785))
* "Disconnected" screen now is not shown directly after a close of the socket, instead the client first tries to
  directly reconnect once, and only if that doesn't work displays the dialog. Should reduce short popups of the dialog
  due to shaky network connections and/or weird browser behaviour when downloading things from the UI.
* Development dependencies can now be installed with ``pip -e .[develop]``
* White and transparent colors ;) are supported for the navigation bar ([#789](https://github.com/foosel/OctoPrint/pull/789))
* Drag-n-drop overlay for file uploads now uses the full available screen space, improving usability on high resolution
  displays ([#187](https://github.com/foosel/OctoPrint/issues/187))
* OctoPrint server should no longer hang when big changes in the system time happen, e.g. after first contact to an
  NTP server on a Raspberry Pi image. Achieved through monkey patching Tornado with
  [this PR](https://github.com/tornadoweb/tornado/pull/1290).
* Serial ports matching ``/dev/ttyAMA*`` are not anymore listed by default (this was the reason for a lot of people
  running into problems while attempting to connect to their printer on their Raspberry Pis, on which ``/dev/ttyAMA0``
  is the OS's serial console by default). Added configuration of additional ports to the Serial Connection section in
  the Settings to make it easier for those people who do indeed have their printer connected to ``/dev/ttyAMA0``.
* Better behaviour of the settings dialog on low-width devices, navigation and content also now scroll independently
  from each other (see also [#823](https://github.com/foosel/OctoPrint/pull/823))
* Renamed "Temperature Timeout" and "SD Status Timeout" in Settings to "Temperature Interval" and "SD Status Interval"
  to better reflect what those values are actually used for.
* Added support for rectangular printer beds with the origin in the center ([#682](https://github.com/foosel/OctoPrint/issues/682)
  and [#852](https://github.com/foosel/OctoPrint/pull/852)). Printer profiles now contain a new settings ``volume.origin``
  which can either be ``lowerleft`` or ``center``. For circular beds only ``center`` is supported.
* Made baudrate detection a bit more solid, still can't perform wonders.
* Only show configuration options for additional extruders if more than one is available, and don't include offset
  configuration for first nozzle which acts as reference for the other offsets ([#677](https://github.com/foosel/OctoPrint/issues/677)).
* Cut off of the temperature graph is now not based on the number of data points any more but on the actual time of the
  data points. Anything older than ``n`` minutes will be cut off, with ``n`` defaulting to 30min. This value can be
  changed under "Temperatures" in the Settings ([#343](https://github.com/foosel/OctoPrint/issues/343)).
* High-DPI support for the GCode viewer ([#837](https://github.com/foosel/OctoPrint/issues/837)).
* Stop websocket connections from multiplying ([#888](https://github.com/foosel/OctoPrint/pull/888)).
* New setting to rotate webcam by 90Â° counter clockwise ([#895](https://github.com/foosel/OctoPrint/issues/895) and
  [#906](https://github.com/foosel/OctoPrint/pull/906))
* System commands now be set to a) run asynchronized by setting their `async` property to `true` and b) to ignore their
  result by setting their `ignore` property to `true`.
* Various improvements of newly introduced features over the course of development:
  * File management: The new implementation will migrate metadata from the old one upon first startup after upgrade from
    version 1.1.x to 1.2.x. That should speed up initial startup.
  * File management: GCODE Analysis backlog processing has been throttled to not take up too many resources on system
    startup. Freshly uploaded files should still be analyzed at full speed.
  * Plugins: SettingsPlugins may track versions of configuration format stored in `config.yaml`, including a custom
    migration method getting called when a mismatch between the currently stored configuration format version and the one
    reported by the plugin as current is detected.
  * Plugins: Plugins may now have a folder for plugin related data whose path can be retrieved from the plugin itself
    via its new method [`get_plugin_data_folder`](http://docs.octoprint.org/en/master/modules/plugin.html#octoprint.plugin.types.OctoPrintPlugin.get_plugin_data_folder).
  * Plugin Manager: Don't allow plugin management actions (like installing/uninstalling or enabling/disabling) while the
    printer is printing (see also unreproduced issue [#936](https://github.com/foosel/OctoPrint/issues/936)).
  * Plugin Manager: More options to try to match up installed plugin packages with discovered plugins.
  * Plugin Manager: Display a more friendly message if after the installation of a plugin it could not be correctly
    identifier.
  * Software Update: Enforce refreshing of available updates after any changes in enabled plugins.

  * [#809](https://github.com/foosel/OctoPrint/issues/809) - Added proper form validation to printer profile editor
  * [#824](https://github.com/foosel/OctoPrint/issues/824) - Settings getting lost when switching between panes in
    the settings dialog (fix provided by [#879](https://github.com/foosel/OctoPrint/pull/879))
  * [#892](https://github.com/foosel/OctoPrint/issues/892) - Preselected baudrate is now properly used for auto detected
    serial ports
  * [#909](https://github.com/foosel/OctoPrint/issues/909) - Fixed Z-Timelapse for Z changes on ``G1`` moves.
  * Fixed another instance of a missing `branch` field in version dicts generated by versioneer (compare
    [#634](https://github.com/foosel/OctoPrint/pull/634)). Caused an issue when installing from source archive
    downloaded from Github.
  * [#931](https://github.com/foosel/OctoPrint/issues/931) - Adjusted `octoprint_setuptools` to be compatible to older
    versions of setuptools potentially site-wide installed on hosts.
  * [#942](https://github.com/foosel/OctoPrint/issues/942) - Settings can now be saved again after installing a new
    plugin. Plugins must not use `super` anymore to call parent implementation of `SettingsPlugin.on_settings_save` but
    should instead switch to `SettingsPlugin.on_settings_save(self, ...)`. Settings API will capture related
    `TypeErrors` and log a big warning to the log file indicating which plugin caused the problem and needs to be
    updated. Also updated all bundled plugins accordingly.
  * Software Update: Don't persist more check data than necessary in the configuration. Solves an issue where persisted
    information overrode updated check configuration reported by plugins, leading to a "an update is available" loop.
    An auto-migration function was added that should remove the redundant data.
* Various fixes without tickets:
  * GCODE viewer now doesn't stumble over completely extrusionless GCODE files
  * Do not deliver the API key on settings API unless user has admin rights
  * Don't hiccup on slic3r filament_diameter comments in GCODE generated for multi extruder setups
  * Color code successful or failed print results directly in file list, not just after a reload
  * Changing Timelapse post roll activates save button
  * Timelapse post roll is loaded properly from config
  * Handling of files on the printer's SD card contained in folders now works correctly
  * Don't display a "Disconnected" screen when trying to download a timelapse in Firefox
  * Fixed handling of SD card files in folders
  * Fixed refreshing of timelapse file list upon finished rendering of a new one
  * Fixed ``/api/printer`` which wasn't adapter yet to new internal offset data model
  * Made initial connection to printer a bit more responsive: Having to wait for the first serial timeout before sending
    the first ``M105`` even when not waiting for seeing a "start" caused unnecessary wait times for reaching the
    "Operational" state.
  * Log cancelled prints only once (thanks to @imrahil for the headsup)

([Commits](https://github.com/foosel/OctoPrint/compare/1.1.0...1.1.1))

## 1.1.0 (2014-09-03)

### New Features

* New REST API, including User API Keys additionally to the global API key. Please note that **this will break existing
  API clients** as it replaces the old API (same endpoint). You can find the documentation of the new API at
  [docs.octoprint.org](http://docs.octoprint.org/en/1.1.0/api/index.html).
* New Event structure allows more flexibility regarding payload data, configuration files will be migrated automatically.
  You can find the documentation of the new event format and its usage at [docs.octoprint.org](http://docs.octoprint.org/en/1.1.0/events/index.html).
* Support for multi extruder setups. With this OctoPrint now in theory supports an unlimited amount of extruders, however
  for now it's artificially limited to 9.
* Log files can be accessed from within the browser via the Settings dialog ([#361](https://github.com/foosel/OctoPrint/pull/361))
* Timelapses can now have a post-roll duration configured which will be rendered into the video too to not let it
  end so abruptly ([#384](https://github.com/foosel/OctoPrint/issues/384))
* The terminal tab now has a command history ([#388](https://github.com/foosel/OctoPrint/pull/388))

### Improvements

* Stopping the application via Ctrl-C produces a less scary message ([#277](https://github.com/foosel/OctoPrint/pull/277))
* Webcam stream is disabled when control tab is not in focus, reduces bandwidth ([#316](https://github.com/foosel/OctoPrint/issues/316))
* M and G commands entered in Terminal tab are automatically converted to uppercase
* GCODE viewer now only loads automatically if GCODE file size is beneath certain threshold (different ones for desktop
  and mobile devices), only actually loads file if user acknowledges that this might be too much for his browser
* Added time needed for printing file to PrintDone event's payload ([#333](https://github.com/foosel/OctoPrint/issues/333))
* Also provide the filename (basename without the path) in print events
* Support for circular beds in the GCODE viewer ([#407](https://github.com/foosel/OctoPrint/pull/407))
* The dimensions of the print bed can now be configured via the Settings ([#396](https://github.com/foosel/OctoPrint/pull/396))
* Target temperature reporting format of Repetier Firmware is now supported as well ([360](https://github.com/foosel/OctoPrint/issues/360))
* Version tracking now based on git tagging and [versioneer](https://github.com/warner/python-versioneer/). Version number,
  git commit and branch get reported in the format `<version tag>-<commits since then>-g<commit hash> (<branch> branch)`,
  e.g. `1.2.0-dev-172-ga48b5de (devel branch)`.
* Made "Center viewport on model" and "Zoom in on model" in the GCODE viewer automatically deselect and de-apply if
  viewport gets manipulated by the user ([#398](https://github.com/foosel/OctoPrint/issues/398))
* GCODE viewer now interprets inverted axes for printer control and mirrors print bed accordingly ([#431](https://github.com/foosel/OctoPrint/issues/431))
* Added `clean` command to `setup.py`, removes old build artifacts (mostly interesting for developers)
* Added version resource on API which reports application and API version
* Made the navbar static instead of fixed to improve usability on mobile devices ([#257](https://github.com/foosel/OctoPrint/issues/257))
* Switch to password field upon enter in username field, submit login form upon enter in password field
* Changed default path to OctoPrint executable in included init-script to `/usr/local/bin/octoprint` (the default when
  installing via `python setup.py install`)

### Bug Fixes

* Properly calculate time deltas (forgot to factor in days)
* [#35](https://github.com/foosel/OctoPrint/issues/35) - GCODE viewer has been modularized, options are now functional
* [#337](https://github.com/foosel/OctoPrint/issues/337) - Also recognize `--iknowwhatimdoing` when running as daemon
* [#357](https://github.com/foosel/OctoPrint/issues/357) - Do not run GCODE analyzer when a print is ongoing
* [#381](https://github.com/foosel/OctoPrint/issues/381) - Only list those SD files that have an ASCII filename
* Fixed a race condition that could occur when pressing "Print" (File not opened yet, but attempt to read from it)
* [#398](https://github.com/foosel/OctoPrint/issues/398) - Fixed interfering options in GCODE viewer
* [#399](https://github.com/foosel/OctoPrint/issues/399) & [360](https://github.com/foosel/OctoPrint/issues/360) - Leave
  bed temperature unset when not detected (instead of dying a horrible death)
* [#492](https://github.com/foosel/OctoPrint/issues/492) - Fixed a race condition which could lead to an attempt to read
  from an already closed serial port, causing an error to be displayed to the user
* [#257](https://github.com/foosel/OctoPrint/issues/257) - Logging in on mobile devices should now work
* [#476](https://github.com/foosel/OctoPrint/issues/476) - Also update the metadata correctly when an analysis finishes
* Various fixes of bugs in newly introduced features and improvements:
  - [#314](https://github.com/foosel/OctoPrint/issues/314) - Use G28 for homing (G1 was copy and paste error)
  - [#317](https://github.com/foosel/OctoPrint/issues/317) - Fixed "load and print" function
  - [#326](https://github.com/foosel/OctoPrint/issues/326) - Fixed refresh of SD file list
  - [#338](https://github.com/foosel/OctoPrint/issues/338) - Refetch file list when deleting a file
  - [#339](https://github.com/foosel/OctoPrint/issues/339) - More error resilience when handling temperature offset data from the backend
  - [#345](https://github.com/foosel/OctoPrint/issues/345) - Also recognize such temperature reports that do not contain a `T:` but a `T0:`
  - [#377](https://github.com/foosel/OctoPrint/pull/377) - URLs in API examples fixed
  - [#378](https://github.com/foosel/OctoPrint/pull/378) - Fixed crash of API call when `getStartTime()` returns None
  - [#379](https://github.com/foosel/OctoPrint/pull/379) - Corrected response code for connection success
  - [#414](https://github.com/foosel/OctoPrint/pull/414) - Fix style attribute for Actual column header
