Label Studio 1.7.2 Release Notes

The Label Studio 1.7.2 Open Source release introduces a new Magic Wand tool for image annotation and significant updates to our audio labeling functionality.

New Feature and Enhancement

Label Studio 1.7.2 includes the following new features and enhancements.

  • Added Magic Wand tool for image segmentation
    • This new community-contributed feature makes it possible to click in a region of an image for segmentation labeling, drag the mouse to dynamically change flood filling tolerance, then release the mouse button to get a new labeled area.

Label Studio 1.7 Release Notes

The Label Studio 1.7 Open Source release now supports larger audio files, millisecond-level controls, and an advanced rendering engine among new features that put Label Studio at the forefront of data labeling for audio files. This release also introduces simplified ways to deploy and manage your Label Studio application using full infrastructure provisioning with Terraform scripts and scalable service management on Kubernetes with Helm Charts deployment.

Breaking changes

Starting with this release, the application will run using a non-root docker user with ID 1001.

If you encounter any permission issues when running the application in a docker container, you can fix them by changing the ownership of the relevant files and directories to 1001.

docker run -it --user root -v `pwd`/mydata:/label-studio/data heartexlabs/label-studio:1.7.0 chown -R 1001:root /label-studio/data/

New Feature and Enhancement

Label Studio 1.7.0 includes the following new features and enhancements.

  • Starting with this release, you can install Label Studio to your cloud infrastructure using the Terraform scripts and Helm Charts.
  • The audio labeling platform introduces the enhancements of the audio player with the ability to annotate audio files up to two hours in length, provide fine-grain annotation controls, and implement an efficient rendering engine that displays the audio waveforms while remaining performant, even with large, and multi-hour audio files. You can now play and navigate through an audio waveform by precisely managing the labeled regions. Regions and relations are simple to manage and manipulate on the audio waveform and interface.
  • This release provides the Comments and Notifications feature that defines how annotators, reviewers, and administrators communicate and receive updates on projects and tasks.
  • Add new header GitHub stars by @Travis1282 in #3040.
  • Update header CSS, GitHub stars, and command block on search by @Travis1282 in #3074.
  • Add swagger docs for AllStorage APIs by @KonstantinKorotaev in #2815, DEV-2914.

Label Studio 1.5.0 Release Notes

The latest release of Label Studio is dedicated to more dynamic and custom ways to define, change, and display label sets. Big new features include the ability to show labels dynamically (as opposed to statically), for example for classification or computer vision tasks use images rather than text for the label name and allow annotators to create new labels and evolve the taxonomy as they work through the dataset.

The Label Studio 1.5.0 release includes the new features and enhancements, breaking changes, and bug fixes.

Important notes about installation

This release has long migrations and they can take up to 1-2 hours depending on your task number (relevant for instances with more than 100k tasks). If you want to avoid them, you should run label-studio --skip-long-migrations and then call label-studio calculate_stats_all_orgs. These migrations affect task counters like total annotation number, canceled number, and prediction number.

New Features and Enhancements

Label Studio 1.5.0 includes the following new features and enhancements.

  • Introduce dynamic labels as a task input through prediction from the model, or from a database lookup instead of having annotators scroll through an extensive list of choices. Dynamic labeling saves time and increases the consistency of labeling the objects.
  • Enhance the labeling methods by creating label sets with images and hyperlinks. This results in a better visual signal for annotators. You can also customize the view of choices to be displayed by using HTML markup.
  • Allow annotators to add new classes in taxonomy as they work through the dataset, without the need to predefine classes.
  • Add support for default settings functionality to the Label Studio Editor.
  • Include the Last updated by column in Data Manager with information about who made the last modifications for any of the annotations in this task at updated_at time.
  • Easily handle the imported tasks by sorting the task IDs in ascending order of filenames.
  • Add the no more tasks screen at the end of the queue. Now, you can go back to the previous task from the end of the labeling stream.
  • Set default y-scale parameter at label config level for audio UI.
  • Overlay timeline on top of the waveform for full height timestamp tooltip.
  • Add a group of APIs to manage labels in the Label Studio.
  • Create a lead time column in Data Manager with averaged lead time per task.
  • Improve the HyperTextLabels regions to no longer shift on annotation submit/ update/ change annotation/ draft to original toggle/ open close task/ undo redo toggle.
  • Improve the performance for API querying the next task in Label Stream.
  • Augment the performance of loading the project lists.
  • In the Quick View mode, the left-side list of tasks is focused on the current annotating task.
  • Add Undo/Redo functionality for audio.
  • Display the column (settings) icon when Quick View is opened.
  • Add support of OCR <TextArea> for editable=false.
  • Enable auto-resize of images to screen option.

Breaking Changes

Label Studio 1.5.0 includes the following breaking changes.

  • All drafts (including drafts without initial annotation and drafts that are attached to annotation) from the current user’s session pass the ML backend for interactive prediction.
  • Set the page_size limit to < 100 values in api/projects/ID/tasks API.

Bug Fixes

Label Studio 1.5.0 includes the following bug fixes.

  • Fixed an issue where selecting the Pan tool wiped out unfinished polygon drawings.
  • Fixed an issue in audio data type, where the View all Annotations mode did not work for some time after the annotation was created.
  • Fixed performance for annotation results filters.
  • Fixed Static Application Security Testing (SAST) security issues in Label Studio Open Source.
  • Fixed an issue where signup permissions were denied for users without an invite link.
  • Fixed security issues reported by the Open Web Application Security Project (OWASP) Zed Attack Proxy (ZAP) scanner.
  • Fixed an issue where required=true was set along with visibleWhen for TextArea and Choices.
  • Fixed an issue where the click action on Create annotations from predictions in Data Manager generated the ANNOTATIONS_CREATED webhook event.
  • Fixed an issue where the usage of relations between <BrushLabels> regions crashed the Label Studio App.
  • Fixed an issue where the TextArea with displayMode="region-list" text lost focus in an OCR project.
  • Fixed image cropping issue.
  • Fixed an issue where Text and Header tags failed to work with integers.
  • Fixed an issue where the label config preview failed when a user applied one custom label config and later replaced it with another custom config.
  • Fixed an issue where the named entity recognition granularity failed to reflect correctly in exported data.
  • Fixed HyperText security breach / JavaScript injection attack. Removed in-use script elements and replaced them with a stub which was replaced later during execution. Only in-use scripts were executed and placed in the appropriate location.

Thank you to all the contributors for making Label Studio 1.5.0 a success!

Label Studio 1.4.0

This release of Label Studio includes a Python SDK, as well as other enhancements including: customizable hotkeys, labeling improvements, the ability to create annotations from predictions, and various infrastructure improvements that make deploying and managing Label Studio easier and faster.
​
Thanks to all of our contributors and people that reported issues!
​

Customize labeling hotkeys

You can now customize the hotkeys used for labeling, included the much-requested ability to customize the hotkey combination for submitting an annotation. See all the details in the labeling with hotkeys documentation. Thanks to Grigoriy Livshits and Schulzjo in issue #941, Flavien Berwick in issue #796, and Nathan Derave, Tram-Anh Nguyen, and Filippo Broggini in issue #208 for requesting this functionality.
Additionally, as requested by Mykola Sharhan in issue #812, this release also includes new hotkeys for Time Series labeling, plus Video, Image, and Audio labeling. Check out the hotkey documentation for more.
​

Prediction and annotation improvements

​

  • You can now use the API or the new SDK to create annotations directly from predictions. Several people in Slack have asked about this functionality, and we're happy to say that it's finally here!
  • Annotations created from pre-annotations include links to the predictions that were used when annotating the task as parent_prediction when you export or retrieve annotations using the API.
  • Similarly, annotations copied from other annotations include links to the annotation used to create the new annotation as parent_annotation when you export or retrieve annotations using the API.
  • You can now delete annotations from target cloud storage when they are deleted from Label Studio.
  • Fixed an issue displaying predictions to annotators in quickview when the option to "Show predictions to annotators" was selected.
    ​

Export improvements

  • Exported tasks now contain more details about the annotation process, such as draft annotations and predicted annotations. These additional details appear in all places that you can export tasks, including files exported using the API or Label Studio UI, tasks saved to target storage connections, and annotations sent to machine learning backends.
  • Improved the new export API that allows you to generate a file for export and control on a granular level what is included. This includes filtering by completed_by or updated_at time, as well as specifying a data manager view ID and exporting only the tasks visible with those filters. See the API docs for create new export.
  • When exporting annotations, the completed_by field can return either the user ID or a full dictionary of user data. It returns the user ID only by default. If you want to see more details about users, set "annotations__completed_by": { "only_id": false }. See the docs for creating a new export.
  • Fixed an issue with UTF-8 characters in export filenames reported by Théo HENAFF in issue #1266.
    ​

Deployment and server management improvements

​

  • Faster Docker build process
  • Label Studio subpath is automatically configured
  • Updated the nginx configuration to have a client_max_body_size of 200MB that can be configured.
  • Added support for MinIO
  • Added OrganizationMember to the Django admin dashboard
  • Now you can use Visual Studio Code Remote - Containers with Label Studio to set up the developer environment and make changes. Thanks to twsl for your code contribution!
  • Docker setup now includes friendlier defaults that avoid CSRF errors for localhost deployments. Thanks to David Sanders for contributing the fix!
  • Fixed an issue where a server hang with Label Studio could lead to an infinite loop and cause the browser to freeze.
    ​

Data management improvements

​

  • Improved the performance of the Data Manager page.
  • Added ordering chaining so that you can, for example order by "Annotators" first, and by "Completed" second.
  • Filter and sort tasks according to the model version used to create specific predictions.
  • Improved and fixed some data manager filtering bugs.
    ​

ML backend improvements

​

  • Added webhook support to the ML backend. You can now set up a webhook that notifies you when an ML backend is connected to Label Studio.
  • Fix issues associated with saving and retrieving model versions in ML backends.
  • Fixed a bug with an error message (ironically) when Label Studio failed to connect to an ML backend. Thanks to David Sanders for contributing the fix!
  • Fix double call of ML backend predict() method for one task [https://github.com//pull/1763] Thanks to Nithishkumar K R
    ​

Storage improvements

  • If you have a cloud data connection set up, you can import task data that references cloud storage URLs such as s3:// or gs:// and the URLs are automatically presigned.
  • Fixed an issue where local storage was listed twice in the storage list API results. Thanks to Eric Hansen for your report in issue #1564.
  • Fixed the content-type for local file storage.
  • Improved streaming access for local file storage.
  • Fixed an issue where GCS credentials were not able to be added in the Label Studio UI for target storage connections.
  • Improve the form filling experience when adding storage details.
    ​

Other improvements

  • It's now even easier to extend the available webhook endpoints to add webhooks to any API endpoint. See how to Create custom events for webhooks in Label Studio and Contribute your own!.
  • The user account page now includes details about your active organization.
  • Project and organization members APIs now include pagination, and you can specify ordering for the organization member API.
  • Made various security improvements to Label Studio.
    ​

Other bug fixes

  • Fixed an issue where the labeling configuration might overflow the text box in code view. Thanks to David Sanders for contributing the fix!
  • Fixed an issue where S3 links to task data did not resolve when referenced in HTML links.
  • The port flag was incorrect when calling MySQL status. Thanks to amansohi for contributing the fix!
  • Fixed issue #1259 reported by LUO Lingxiao and Yogesh Kumar where labeling configurations containing a single choice option failed.
  • Fixed an issue with validating imported paragraphs data when using the Paragraphs tag with valueType=url
    ​

Labeling and tag improvements

  • Emoji and special characters are now handled properly when performing Named Entity Recognition (NER) tasks on text with those.
  • When using the whenLabelValue= parameter to do conditional labeling, you can now specify multiple comma-separated label values.
  • Updated the Video templates to use the new Video tag instead of the HyperText tag.
  • Added the visual tag to collapse data when labeling.
  • Update the tag so that it can be used with control tags and added a new Tabular Data template.
  • Perform validation with the HyperText tag when used with nested items.
  • Improve the top navigation bar to make the task ID selectable and update the layout.
  • For selected regions, display the text.
  • Added the ability to view task history with previous and next buttons when labeling. Thanks schafsam for your request in issue #1098.
  • Added an indicator to predicted regions, making it easier to identify which region is a pre-annotation and which is a manual annotation on the task.
  • Add a link on the region panel between predictions and annotations so that you can see which annotation was created from which prediction.
  • Returned the option to "delete all regions", which went missing. Thanks to David Sanders for your report in issue #1645.
    ​

    • HTML labeling improvements

    • Updated the way that HTML annotations are stored. Prior to this change, paragraph text highlighted for labeling would have an xpath with /main/div[1] and the exported annotation would include the <p> tag and text. Now, the xpath for regions like this is /main/div/p/text()[1].
    • Fixed an issue with HyperText where excess labels were applied to multiple spans inside of one text region. Thanks to Piotr Podbielski for your [contribution](https://github.com/heartexl...
