1.4.0 ​

Release 2025-11-03 - Blog post - YouTube video

Streams ​

  • Stream Management: Users can create, edit, and duplicate streams, as well as create mirror streams.
  • Stream Messages History with Filters: The realtime mode of stream messages can get turned off. Then the list of messages is shown (ascending) with the possibility to filter the list by start date, sequence or a subject.
  • Republish Configuration: Republish settings are displayed in the stream configuration page.
  • More Mirror Details: The Config view of a stream now shows all the mirror details if its a Mirror.
  • Help Texts for Configurations: The Config view of a stream now shows help texts for the different configuration options to help the User to better understand NATS.
  • Consumer Help Texts: The Consumer Details view now includes helpful explanations for all configuration options. Hover over any field to see detailed descriptions, making it easier to understand consumer behavior and settings.
  • NATS 2.12 Stream Support: Added support for new NATS 2.12 stream configuration options: Allow Msg Counters (allow_msg_counter), Allow Msg Schedules (allow_msg_schedules), Allow Atomic Batch Publish (allow_atomic_publish), and Persist Mode (persist_mode, Default/Async). See the NATS Server 2.12 release blog for details.
  • New Relations Graph: Lets you discover the relations of a stream to other streams. It can visualize a max depth of 5.
  • Consumer pause/resume: Users can now pause/resume all or single consumers of a stream.
  • Copy Stream Config: New context menu option to copy the raw stream configuration to clipboard in NATS CLI-compatible JSON format.
  • Terraform Configuration Export: Generate Terraform HCL configuration for streams directly from the UI. Available in the stream form (create/duplicate modes) and stream details dropdown menu. The generated configuration is based on terraform-provider-jetstream v0.2.1 and automatically filters out NATS system metadata. Configurations can be saved as .tf files for infrastructure-as-code workflows.
  • Stream Leader Step-Down: You can now manually trigger a leader step-down for clustered streams (use Shift+L or the stream dropdown menu). This is useful for maintenance tasks, rebalancing cluster load, or troubleshooting. The dialog helpfully explains when this operation is available and why it might not be (e.g., when your stream has no replicas).
  • Remove Followers from Cluster: Remove one or more followers from a stream's RAFT cluster via the stream dropdown menu. Select which followers to remove, and the operation shows real-time progress for each removal. This is useful for removing specific servers from a stream cluster during maintenance or rebalancing operations.

Bugfixes ​

1.3.0 ​

Released: 2025-04-01

UI/UX ​

  • Completely rewritten layout engine, which adds tabs, split views, and many other productivity features. It stores open tabs and split views on disk, allowing you to quickly resume where you left off last time.
  • Improved the ranking algorithm for searching connections in the connection bar.
  • Quick open feature (Cmd+p or Ctrl+p): The results are now cached, which makes it much faster to switch between Streams/KVs/etc.. The search ranking algorithm is more aligned with typical IDEs, wich makes it easier to find the items. You can clear the cache by reloading the navigation (F5).
  • Navigation:
    • The navigation now loads up to 2000 found entries per type (streams, KVs, etc.).
    • The performance got improved for handling large clusters with lots of streams, KVs, etc.
    • New hotkey: press Strg+Shift+R or Cmd+Shift+R to refresh the navigation
    • Increased readability of the navigation entry texts

Streams ​

  • Message Transformation: You can now transform the message payload with a command that should run before showing the message payload. It can be configured differently for every connection. It is also possible to overwrite the settings for individual streams.
  • Message Details: You can now view the latest message by subject.
  • New Column "Headers" that shows you the number of headers in the message
  • Realtime mode → Setting gets stored for the individual streams when you use the realtime mode switch. You can configure the default realtime mode status in the connection settings.

    • You can now view the latest message by subject.
    • Increased performance fetching multiple messages by sequence/subject
  • Stream Config:
    • If the stream is a mirror of another stream, you can now navigate to the original stream by clicking on the name
    • NATS 2.11 support:
      • "Allow Message TTL" is now shown in the config.
  • Consumers:
    • Redesigned consumer details view that lets you quickly switch between consumers via an input field.
    • NATS 2.11 support:
      • The consumer list and consumer details indicate whether the consumer is paused.

  • Better key visibility: when a key is opened, the whole vertical space is now used to show the value.
  • Refresh key: When a key is open, you can simply refresh the key via a button next to the key name.
  • KV Config: It now shows the bucket name to copy it to the clipboard with one click. Other shown config config values got the copy to clipboard feature.
  • Removed on the KV > Content view: Number of keys in the stats: When a KV gets opened, the Number of Keys are not determined for the stats, as this slows down the opening for buckets with a large number of keys and frequently changing values. You can still see the number of keys in the keys panel on the left.
  • When the loading of KV bucket fails, it can be retried via a button.
  • Bugfix: When the KV bucket loading failed, an error message with error details is now shown.
