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.
  • Read virtual annotator filters from local storage as a fallback by @robot-ci-heartex in #3089, DEV-3572.
  • Add mixin to Project to support mechanism to cancel old jobs by @KonstantinKorotaev in #2547, DEV-2075.
  • Load task with given comment by @robot-ci-heartex in #3250, DEV-3750.
  • Support updated_by for annotations by @hakan458 in #3244, DEV-3259
  • Queue management min backend by @triklozoid in #3282, DEV-3756.
  • Support for Updated_by field on annotation level in Update, Accept , and Reject by @hakan458 in #3318, DEV-3259.

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.

Label Studio 1.3.0

Interactive ML-assisted labeling

The biggest update in this release is introducing... Interactive ML-assisted labeling with pre-annotations! You need to set up a machine learning backend to use this feature. Read all the details in the release blog or in the machine learning documentation.

Thanks to @juan57 for the suggestion and also to @xuankhanhdo, @amant555, and @prathameshk for requesting similar functionality.

Improved semantic segmentation

Thanks to diligently-reported issues from @royschwartz2 and the hard work of our frontend team, there are many improvements to performing semantic segmentation.

  • You can adjust the eraser size.
  • Improved the performance of semantic segmentation after several regions have been annotated.

There are also some bug fixes:

  • Highlighted regions and labels now display in the correct location after zooming.
  • Submitting the task after hiding annotations does not delete the annotations.

Delayed export options for improved performance

To improve performance when exporting results from large labeling projects, you can now choose to export a file with the results. It's a two step process, starting with creating an export file and then downloading the export file with the results.

Thanks to @MiguelFreire, @shubhangi27397, @R-Peleg, and @twsl for reporting and discussing export performance.

Cloud storage improvements

Data manager improvements

  • Choose to label all tasks, or filter the data manager and label only the tasks as displayed.
  • Improvements to the filtering behavior as requested and pointed out by @karelserruys-foodpairing and @AlexRoss-WHS.
  • You can now display and filter by annotation ID in the data manager.
  • Moved the import and export buttons out of the main header. Export or import data while viewing the project data manager instead of on any page in Label Studio.

Labeling improvements

  • When labeling, in the regions sidebar you can see the type of region that was created with an icon.
  • Select multiple regions at once using ctrl+click, as requested by @mbuet2ner.
  • Use the alt + . keyboard shortcut to cycle through entities, instead of alt+tab as requested by @danielcrane.
  • A new hint parameter for the Label tag lets you add a tooltip for specific labels.
  • Improved performance of the label stream, reported by @anshul-dt, @tristanratz, and @iakremnev.

Other improvements

  • You can now use MySQL as a database backend with Label Studio thanks to contributor @dehydr8. See the details in #1385.
  • Contributor @jeroenboeye fixed a bug in the export API documentation example.
  • Improvements to the wait for postgres shell script from contributor @piraka9011.

Documentation improvements

  • Revised Tag documentation now includes more details, examples, and sample results JSON to make crafting predictions for different types of labeling easier.
  • Ability to copy code examples and sample JSON with one click.
  • Improved readability of code examples by updating the colors used for highlighting.

Bug fixes

  • Fixed an issue where polygon points and keypoints were large after zooming an image.
  • Fixed issues with the Taxonomy tag reported by @ynouri and @irogers
  • Fix some errors using the ctrl+enter hotkey to submit tasks.
  • Fixed issues with hypertext labeling, such as allowing variables anywhere in the tags. For example: <Text>Title: $title</Text>.
  • Fixed an issue where offsets were occurring incorrectly in NER annotation, reported by @Lolologist.
  • Fixed an issue where boolean types weren't working for values in a labeling configuration.
  • Fixed a bug where relations didn't appear in the UI after returning to an annotation with relations. Thanks to @joeydb94, @kaitco, and @3nuc for reporting bugs with relations.
  • Fixed a bug with resizing images affecting bounding boxes. Thanks @VladYushchenko for the report!

This release closes the following issues:
#1236, #1174, #1134, #655, #771, #1091, #1371, #970, #671, #1008, #476, #1262, #1244, #1243, #1205, #1072, #1026, #1014, #1141

Release 1.1.1

Label Studio 1.1.1 Release Notes

New Functionality

This version of Label Studio includes the following improvements and new functionality.

Cloud storage improvements

  • Recursively scan S3 buckets connected as source storage.
  • URLs in tasks that reference objects in connected cloud storage buckets or blobs automatically resolve. If you create a cloud storage connection and import data with URLs such as s3://... or gs://..., the objects at those URLs automatically resolve in your labeling tasks.
  • Specify Google Cloud Storage (GCS) credentials in a JSON file when setting up GCS source storage, instead of using the environment variable GOOGLE_STORAGE_CREDENTIALS. See Sync data from external storage.
  • For form fields that expect JSON, such as when setting up external storage, the JSON is now validated.

Tag and Template improvements

  • Add support for a Video tag to be used for classification.
  • Improve the Taxonomy tag.
  • Added a Repeater tag for dynamic labeling. Thanks to @gfauchart for your contribution!
  • Optimize bbox and ellipse creation for image segmentation.
  • Updated the Video Timeline Segmentation template.

Other improvements

  • If you're using an ML backend, you can now select the specific version of the model to use when showing predictions to annotators. See Set up machine learning.
  • When importing data that includes annotator email addresses in the completed_by field, Label Studio now matches the annotator email addresses to existing annotators and assigns those annotators to the tasks. If the completed_by field is undefined, a validation error is shown.
  • When importing tasks, you can now specify the was_cancelled attribute for a task to indicate that it was skipped.
  • Filter predictions by specific tasks or project IDs when using the API.
  • Improvements to exporting audio transcription data, and CSV export is expanded to include created/updated_at fields and lead_time data.
  • Improved performance when exporting tasks and annotations, as reported by @R-Peleg .

Bug Fixes

This version of Label Studio includes the following bug fixes.

Label Studio UI

  • Fixed an issue where the Create button stopped opening the modal after it was closed. Thanks @yoku2010 for your contribution!
  • Fixed bugs with the filters on the data manager, including integer filters and filtering with the is_empty argument. Thanks @alex-eurec for your report.
  • Fixed the TTL settings for S3 and cloud storage.
  • Fixed a bug where the presigned URL toggle was not being respected. Thanks @nader-bitstrapped-com for reporting this issue!
  • Fixed an issue with S3 links with prefixes and white space.
  • Fixed an issue deleting annotations.
  • Fixed a bug with the size of the canvas when viewing all annotations for a task.

Label Stream

  • Fixed a bug where skipped annotations appear in the label stream for other annotators to label and annotators working from a manually-assigned queue continued to be assigned skipped tasks.
  • Fixed an issue where regions were missing from draft annotations.
  • Fixed an issue where the zoom button moved while an image was loading.
  • Fixed an issue when labeling with brushes.
  • Fixed an issue where the brush area did not display correctly after zooming an image.
  • Fixed an issue with minimum size of shapes.
  • Fixed polygons being distorted when switching between original and draft annotations.
  • Prevent a polygon from being created with fewer than 3 points.
  • Fixed several issues with the RichText tag, including issues scrolling to region, text region offsets, selection range size in different browsers, incorrect selection in word, sentence, and paragraph granularity mode, overlapping ranges, and trimming spaces. Thanks to @uklft, @sharkzeeh, @1ytic, @lluissalord, @inzomiac, @stantonius, @jimsandwick99, @function2-llx, @somejonus, and @prohor33 for your reports!
  • Fixed an issue when using hotkeys on choices with the Taxonomy tag.
  • Fixed an issue when using relations with rotating, zooming, and erasing regions on images.

Other bug fixes

  • Fixed an issue where a task might be duplicated in export results when there is more than 1 annotation per task. Thanks @HarshSharma12 for your report.
  • Fixed issues with the ./serve_local_files.sh script.
  • Fixed an issue where ML backend error responses were improperly handled.
  • Fixed an issue running SQLite database on Windows.

Release 1.1.0

Version 1.1 Release Notes

Multi-tool image labeling

Add different types of regions to your images, for example, rectangles, ellipses, polygons, brush masks, and keypoints. Combine the different types of Control tags in the labeling configuration that you create for the labeling interface. See the labeling documentation for more.

Add regions without labels

When adding predicted annotations or when doing labeling in Label Studio, you can add regions without assigning labels. See the pre-annotation documentation for details.

Quickly create and remove regions

Add a rectangle or an ellipse to your image with just two clicks, or double click to create a polygon, rectangle, or ellipse.

If you accidentally select a point on an image while creating a polygon, just double click to remove the erroneous point and continue creating the region. You need to have at least three polygon points to be able to remove one.

Switch visibility for all regions at once

While you could previously show or hide regions one by one, now you can toggle the visibility of all regions at once, and also hide all regions for a specific label at once.

YOLO export support

Export image annotations in a text format compatible with YOLO v3 models. Thanks to @johnson7788 for his PR!

OCR improvements

Write the text for a selected region in the sidebar, rather than at the bottom of the labeling interface screen.

Filter the data manager by annotators

You can now filter the data manager by annotator, letting you create different views and tabs for the tasks completed by different annotators, and more easily review the annotation progress by annotator on the data manager.

Performance improvements

Various performance optimizations to make loading hundreds of bounding boxes on images faster.

Create tokens for users when you start Label Studio

You can now create tokens for users from the command line when you start Label Studio. This makes it easier to integrate Label Studio with your automated pipelines because you can specify a token to use with the API rather than locating the token in the Label Studio UI.

label-studio --username test@example.com --password opossum --user-token token12345

See more in Set up user accounts in the Label Studio documentation.

Bug fixes and updates

This release also includes various bug fixes and smaller updates:

  • Added multi-select capabilities for bounding box and other object detection regions. Thanks to @mbeut2ner for requesting this feature in #655.
  • Updated examples for serving Label Studio behind a proxy with a subpath.
  • Fixed issue when exporting completed tasks.
  • From contributor @xhuaustc, improved the wait-for-postgres.sh script to provide a better experience by using environment variables.
  • Added an environment variable, ENABLE_LOCAL_FILES_STORAGE (true by default), for cases when you might want to disable local file storage as an option entirely.
  • Fixed URL building when using a custom hostname or subpath that was breaking some user experience in the Label Studio UI.
  • Contributor @SAdnen fixed an issue with the Docker compose file that caused the server to get stuck at startup, an issue also reported by @suvojit-0x55aa.
  • Fixed an issue where the storage modals to add storage using Label Studio UI did not appear.
  • Fixed console warnings for MobX (out of bounds).
  • Fixed an issue with relations for remotely loaded data.
  • Fixed an issue with adding two sets of Rectangle Labels to the same labeling interface configuration.
  • Fixed issue #1072 and #1026 with relations appearing for the Text tag with valueType=url, reported by @joeydb94 and @3nuc.
  • Fixed issues with erasing brushes reported in #492 and #867 by @tristanratz and @royschwartz2.
  • Fixed issues with NER labeling causing text highlighting to be incorrectly offset from the selected region reported in #539 and #1008 by @blanchefort and @Lolologist.
