Dark Theme arrives at long last in Studio 3T 2019.5.

Headline Feature

Here Comes the Sun Dark Theme

You spoke; we listened. Say hello to Dark Theme: the much-awaited, most user-upvoted feature in Studio 3T history. Your eyes will thank you during those late-night coding sessions.

You can now opt to use Studio 3T in either the native Light or new Dark Theme by going to Preferences > General > Enable Dark Theme.

Compatible with MongoDB 4.2.

Fixes and Improvements

  • SQL to MongoDB Migration – By default, a mapping for the _id field is now created for the source table’s primary key.
  • SQL to MongoDB Migration – When connecting to a new SQL server, the validity of existing configured mappings are automatically checked.

      Hi Jason,

      Hm, that’s odd. Studio 3T should’ve updated automatically but in case you have an MSI updater we recommend you check the latest version manually.

    Dark mode is looking nice, but still need much amount of improvements, like list-view captions must be in solid black colors, black comboboxes, etc. Most of all I wish a real UI improvement – a horizontal scrolling with shift + mouse scroll as everywhere in other software.

    Same here, latency is very high it becomes totally unusable, at around 1-2 seconds per character type. Can you allow downgrade for the meantime?

    Not related to the Black theme (I hope) but the initial startup time seems to have taken a BIG hit :/ – Can take up to 10/15 seconds to start up the program here. Was not really professional when doing that on a live demo yesterday :/

      We’re very sorry to hear the latency affected your presentation, though you’ll be glad to hear this is a known issue and our devs are working hard to fix it ASAP.

      Thanks for understanding,
