April 2023#

Component        Changes and highlights
  Integration: neptune-aws 1.0.1 Added missing dependency to requirements.
  Web application When filtering runs or other objects by owner, service accounts are now included in the listed owners. Fixed an issue with search when an object contained more than 10 000 fields of the same type.
  Web application Our redesigned web app is live for everyone. You can read about the changes and next steps on the Neptune website .

March 2023#

Component        Changes and highlights
  Integrations The following integration libraries have been updated to support neptune 1.x, among other things.
  Web application
  • Previews of Markdown files are now rendered properly.
  • Multi-line descriptions are rendered correctly in the table view.
  Python client library: neptune 1.1.1 Proper error handling when filenames provided with sys.argv are too long.
  Python client library: neptune 1.1.0 We reworked how Git tracking works: You can now specify the path where Neptune should look for a Git repository, or disable the logging of Git information completely.
  Python client library The package name has been updated from "neptune-client" to "neptune" also on conda.
  On-prem: 2.3.5 New features include service accounts, the redesigned image gallery, metadata tree search, and the ability to register a model directly through the web app (see the Product Portal for more). Also adds support for the 1.x version of the Neptune Python client library.
  Web app – new UI We've been working on a redesign of our web application. You can now opt into the beta version and give it a try. Log in to the app and click the link in the banner, or access it later from the user menu in the top-right corner.
  Web application
  • Improved performance of generating thumbnails for image series.
  • Fixed an issue with the scrollbar when the legend tooltip is visible in the chart widget.
  Web application
  • Improved rendering of several widgets (charts, image galleries) on a single page. Before this change, large widgets would cause the browser to hang, whereas they now load instantly. Scrolling performance is also smoother, and the local state of widgets is preserved while scrolling.
  • Fixed an issue where grouped model versions don't expand.
  • Enabled compression in table view API requests, which improves the loading of the runs table.

February 2023#

Component        Changes and highlights
  Python client library: neptune 1.0.2 Released a fix to properly handle expired OAuth tokens.
  Python client library: neptune 1.0.1 With our first major release of the Neptune client library, the "new" API is now officially the main one. See Upgrade the Neptune client library for how to get the new package, and check out the full list of changes in the neptune 1.0 upgrade guide.
  Web application In image widgets, you can now scroll the image if it's larger than the widget preview size. In interactive CSV tables, the data is now rendered properly for column names that contain dots.
  Web application We fixed a couple of issues: a saved dashboard now retains the y-axis scaling if it has been changed to logarithmic, and deleted projects no longer cause the app to crash when viewing usage statistics. We also further tweaked the image gallery.
  Python client library: neptune-client 0.16.17 Added support for the newly released Neptune-AWS integration.

January 2023#

Component        Changes and highlights
  Web application As a workspace member, you no longer lose access to a project you created if you set the visibility to "workspace" and then back to "private". We also ensured that data is deleted more thoroughly when deleting projects, dashboards, objects, and other things that contain user data.
  Integration: neptune-aws 0.1.0 In our first release of the Neptune-AWS integration, we expose the init_run() function that reads the Neptune API token and project name from AWS Secrets.
  Python client library: neptune-client 0.16.16 We've deprecated the name argument in init_project() as well as all management functions where the name of an existing project or workspace is passed. Use the project or workspace arguments instead:



  Web application The image gallery has received further improvements. In the Source code view, we tweaked the Git info a bit – for example, remote URLs are now rendered as clickable links. As for the table view, due to a technical limitation, we now limit the number of indexed characters in String fields to 1024 characters. This means that for runs table search, only the first 1024 characters will be considered.

December 2022#

Component        Changes and highlights
  Web application When you've grouped runs in the table view, you can now bulk-select all runs of a group for comparison. We've also updated the image gallery with multiple enhancements and new features, such as the carousel view mode.
  Python client library: neptune-client 0.16.15 We fixed a Windows issue with entrypoint script upload when the entrypoint and source files don't share the same drive.
  Python client library: neptune-client 0.16.14 We want to make the log() method more intuitive, so we've released the methods that will eventually replace it: append() and extend(). They're used to create a series of values, appending either a single value or a collection of values at a time, respectively. (It was always possible to append one or multiple values with log(), but we're now separating those into their own methods.)
  New integrations
    Two new integrations have been released:
  • The Neptune-skorch integration has been updated to work with the new Neptune API as well as the legacy one.
  • Integration with ZenML – Neptune is now supported as an Experiment Tracker flavor of the ZenML framework.
  Web application In the model versions table, we fixed an issue where suggested columns would not load properly.

November 2022#

Component        Changes and highlights
  Web application In the runs table, we fixed a Firefox scrollbar issue and disabled the "Apply" button if you go to manage tags but no changes have actually been made. In the run and comparison views, we fixed a bug where unauthorized users would be able to save changes to dashboards. We also tweaked the image gallery a bit.
  Python client library: neptune-client 0.16.13

We increased the size limit of images from 15 MB to 32 MB when logging them as a series.

We also made some tweaks to how Neptune handles junk (local data that has already been synchronized or trashed):

  • When you run a script with Neptune, junk metadata is automatically cleaned.
  • The junk data is also cleaned when running the neptune sync CLI command.
  • For any junk that might linger in the .neptune folder, we added the neptune clear CLI command for manually clearing the data.

  Integration: neptune-lightgbm 0.10.0 We updated the create_booster_summary() function to log tree dataframes in CSV instead of HTML format, and changed the default value of the log_trees_as_dataframe parameter to False. We also made some package and import related fixes.
  Integrations (multiple) We made some import fixes and package-related updates to several of our integration libraries: neptune-prophet 0.4.1, neptune-tensorflow-keras 1.2.0, neptune-fastai 0.10.4, neptune-xgboost 0.10.1, neptune-sacred 0.10.1, kedro-neptune 0.1.4, and neptune-sklearn 0.9.7.
  Integration: neptune-optuna 0.10.0 We added support for multi-objective training.
  Python client library: neptune-client 0.16.12
    Changes to the File field type:
  • We added a new method from_path(), in case you need to specify the file path and extension separately.
  • When creating the file object with from_stream(), you can only log the content from the same stream once.
  • The neptune status CLI command was changed to also show trashed objects.
  Web application We fixed some issues with image comparison and widget dropping in fullscreen mode.

October 2022#

Component        Changes and highlights
  Python client library: neptune-client 0.16.10
  • For tracking artifacts, we've added support for Google Cloud Storage.
  • Methods that fetch objects in table format (such as fetch_runs_table()) no longer query trashed objects.
  • The way we detect the entrypoint file, source files, and Git repositories is now more strict and consistent than before.
  • Due to recent PyTorch Lightning changes, we've removed the jsonschema requirements.
  • The following alternate ways to install neptune-client now work properly: pip install git+ and pip install . (after cloning the neptune-client repository).
⚠ Ahead of the 1.0 release, we've marked the following as deprecated:
  • The legacy API.
  • The methods get_last_run(), get_run_url(), get_project(), and init().
  • Implicit casting of unsupported types to String when using log() or assign() (a.k.a. =). What does this mean? So far, if you attempt to log a value that is not among the supported neptune.types (such as a tuple) Neptune silently logs it as a string. As of 1.x, you're expected to use str(value) if you want it to be logged as a string; otherwise an exception will be thrown in the case of unsupported types.
  Web application We've revamped the image gallery! To analyze images logged as series, you now have more options for displaying and navigating the samples throughout the training process.
  Integration: neptune-tensorflow-keras 1.1.0 We fixed a bug that crashed the integration when the input layer of a neural network didn't have the input_shape parameter defined or the model was not built.

September 2022#

Component        Changes and highlights
  Python client library: neptune-client 0.16.8
  • We've improved the Neptune integration with 🤗 Transformers, which was released with version 4.22.0 . For the updated functionality, see the 🤗 Transformers guide.
  • As part of the management API, you can now move runs or other objects to trash with the trash_objects() function.
  Python client library: neptune-client 0.16.7
  • When resuming a run or other object, we've introduced a new, unified parameter for specifying the ID of the object: with_id.
  • When fetching a table of objects (for example, with project.fetch_runs_table() you can use the new columns parameter to specify which fields to include as columns in the table, rather than having all fields returned.
  • Neptune no longer hangs indefinitely if the synchronization thread has stopped when wait() is called. The process also finishes faster when you call stop().
  Integration: neptune-tensorflow-keras 1.0.0 We've added a bunch of new functionality to our Keras integration, such as saving the model summary and parameters used for fitting the model. See the integration changelog for details.
  Integration: neptune-prophet 0.4.0 The Neptune-Prophet integration has been released! Try it out: Prophet integration guide

July 2022#

Component        Changes and highlights
  General If you set a custom run ID, it's now stored in the system namespace of the run. You can access it normally by using the fetch() method on the "sys/custom_run_id" field.
  Web application
  • When comparing artifacts, the diff view was adjusted to detect and highlight differences of fewer characters than before.
  • Fixed issue with opening files with upperCase extension.
  • Friendlier search/filtering options for object size ("sys/size") and model version stage ("sys/stage").

May 2022#

Component        Changes and highlights
  Python client library: neptune-client 0.16.3 You can now fetch model objects from a project with the new fetch_models_table() method, and we changed the fetch_runs_table() behavior to match all listed tags instead of any.

There was bug in multi-part upload and an issue with the processing of deletion followed by file or artifact upload in a single batch, both of which are now fixed.

  General We launched the Organization plan.
  Web application Table previews are now interactive. In the runs table, we fixed the views dropdown z-index. The "run label", which determines which fields are displayed in legends, was renamed "pinned columns".

We also improved the visual feedback on compare selection, fixed runs table CSV downloads so that they no longer include trashed runs, and fixed fuzzy search exact match being listed first.

  Python client library: neptune-client 0.16.2 You now have the option to sync only offline runs inside the .neptune folder. We also fixed the handling of server errors for init_model() and init_model_version().

April 2022#

Component        Changes and highlights
  Web application We now support preview of BMP and WebP files. And you have the option to log in via your Microsoft account.
  Python client library: neptune-client 0.16.0 We added Python 3.10 support while dropping support for Python 3.6 and below. If a file changes during upload, we now restart the upload.
  R package: neptune-r 0.2.3 We updated the package to install neptune-client version 0.16.x by default and still be compatible with neptune-client 0.15.x.
  Integration: kedro-neptune 0.1.0 Adapted the plugin to the Kedro 0.18 release. Dropped support for Kedro 0.17 (incompatible with 0.18) and Python 3.6 (unsupported by Kedro 0.18)
