1.7.2

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.

1.7.0

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.
  • Introduce Terraform modules for provisioning Label Studio/Label Studio Enterprise on Amazon Web Services(AWS).
  • Launch the Heartex library for Kubernetes infrastructure using the Kubernetes Helm charts. Now, you can scale your Label Studio deployments with Kubernetes and Helm orchestration features.
• 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.

Release 1.5.0

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!

Release 1.4.1

Notable changes

Starting in this version, when you add an ML backend, a webhook is created to send an event to your ML backend each time an annotation is updated or created. Alongside this change, the following has also changed:

• The completions parameter of the fit() method is deprecated and will be removed in the next release.
• "Start model training after any annotations are submitted or updated" is now unchecked by default.
• Requests to the /train API endpoint now include a timeout.

See train a model with your ML backend for more details about this change.
