Mingo 2026.5.0
New Themes
Eleven new color schemes added alongside the existing Light / Dark / Auto, with live preview while browsing in Settings (selection reverts on cancel):
- Dark variants — Rosé Pine, Nord Frost, Midnight Ocean, Catppuccin Mocha, Black & Gold (Luxury), The Matrix
- Light variants — Spice Melange (Warm Sand), Sakura, Mint, Solarized Light, Space Odyssey
Spice Melange is my favorite :)
Import / Export — UI overhaul
Import
- Cleaner single-row header with Open / Save inline; removed numbered step labels.
- New drag-and-drop file-import zone.
- "Clear" button to discard pasted/loaded import data.
- Inline error block and live "N documents found" counter.
- Larger, more visible "Import N documents" primary action with spinner state.
- Upsert pairing field placeholder now suggests
_id, with explanatory tooltip. - Sample preview is now only rendered for CSV imports.
Export
- CSV options reorganized into a cleaner two-row grid: separators / wrapper / "Only wrap strings" on top, Headers and Columns below.
- "Prefill root fields" button moved next to the Columns textarea with an explanatory tooltip.
- Help text (available variables, example) moved to a compact help line under the Columns box.
- The ObjectId-not-native warning is now a subtle inline notice instead of a button.
Dump / Restore improvements
- Per-collection restore. When restoring from an archive or directory, Mingo now scans the source and shows a checklist of all collections found. Select all / Invert / Select none controls included; choosing a subset restricts the restore.
- Auto-detection of gzip archives — no longer relies solely on the gzip option flag; sniffs the file's magic bytes.
- More reliable database/collection extraction from archives — parses BSON
dbfields and embeddedcollectionNamemetadata instead of brittle namespace regex, and reads up to 2 MB (was 512 KB). - Collection list is now alphabetically sorted in the grouped view.
- Skips
system.*collections from the detected list.
AI provider model catalog refreshed
Updated to current-generation models across all four providers:
- OpenAI — added GPT-5.2, GPT-5 Mini, GPT-4.1 / 4.1 Mini / 4.1 Nano; removed GPT-4 Turbo, o1, o1 Mini. New default: GPT-4.1.
- Anthropic — added Claude Opus 4.6, Sonnet 4.6, Sonnet 4.5, Haiku 4.5; removed Claude 3.x and the older Sonnet 4. New default: Claude Sonnet 4.6.
- Google — added Gemini 2.5 Pro / Flash / Flash-Lite; removed Gemini 1.5 Pro / Flash and 2.0 Flash. New default: Gemini 2.5 Flash.
- xAI — added Grok 4.1 Fast, Grok 3, Grok 3 Mini; removed Grok 2 / 2 Mini. New default: Grok 3.
- Test-connection logic and fallback model defaults updated to match.
Fixes & polish
- Tabs: renaming a tab now accepts an empty name (clears the custom name) instead of being rejected.
- Query history context menu: added a Copy action; menu now appears for both filters and selectors (previously selector-only).
- Truncate collection(s): the "Truncating…" toast no longer auto-dismisses while the operation is in progress.
- Workspaces: fixed a crash on certain restored states where workspaces had missing
tabs/activeTabsarrays. - MingoEditor: editor now fills its container width.
- Connection forms: URI inputs no longer use browser URL validation, so all valid Mongo connection strings are accepted.
