1.8.0 - Lakehouse Real-Time warehouses
- New: connect to Lakehouse Real-Time SQL warehouses; every feature
works on them
(Discover Tables, Browser panel, Custom Query and Save in project,
live layers,
Update Layer Data, Genie, Explain this Map), with OAuth or a personal
access token
- New: one-click install of the Databricks SQL kernel Real-Time
warehouses use,
offered from Sign in, Test Connection, Discover Tables and the Browser
panel; no restart
- Improved: OAuth on Real-Time warehouses reuses the plugin's saved
sign-in
- Improved: geometry from Real-Time warehouses appears as on standard
warehouses

1.7.1 - Installer and documentation tidy-up
- Improved: the dependency installer uses the standard
databricks-sql-connector package
- Lakehouse Real-Time warehouse support is planned for a later release
- Docs: README use cases and a full CHANGELOG.md

1.7.0 - Explain this Map with frontier models on Databricks
- New: Explain this Map: one click sends the current map to a frontier
model on your
Databricks workspace (Foundation Model APIs) and streams back an
explanation
- New: no API key or extra subscription: uses your existing Databricks
sign-in
- New: model picker (image-capable models on your workspace), prompt
presets (explain,
report summary, patterns, caption and alt text, next steps) and custom
prompts
- New: follow-up questions, copy, and save as Markdown with the map
image
- The map's facts (area, scale, layers and what each style encodes)
are sent with the
image so answers use your real layer and field names
- Improved: OAuth sign-ins renew well ahead of expiry, so long Genie
One and Explain
this Map sessions run without interruption
- Improved: busy maps (for example with a detailed basemap) are sent
as JPEG so they
always fit the model's image limit
- Improved: Genie Agent and Genie One toolbar buttons use the official
Genie icons

1.6.1 - Simpler, more secure project sharing; summary-table layers
- Improved: every Databricks layer now links to your saved connection
by name, so
projects carry only the connection details and are easier to share
with your team
- Improved: projects from earlier versions are upgraded automatically
when opened
- Improved: credentials for connections you haven't saved stay in
memory for the session
- New: Custom Query "Add as Layer" now also creates layers from
queries without a
geometry column (e.g. summary tables)

1.6.0 - Save custom SQL queries as project layers (issue #3)
- New: Custom Query "Save in project" — the query is saved in the .qgz
and
re-queries Databricks when the project opens (like PostGIS SQL layers)
- New: project layers fetch only the visible map area; select,
identify and refresh work
- Improved: project layers link to your saved connection by name, so
projects are easy to share
- Fixed: Databricks data provider (GEOMETRY(n)/GEOGRAPHY(n) columns,
extent, Multi* types)

1.5.1 - Security hardening and Qt6 readiness
- Improved: stronger SQL handling: table and column names of any kind
are quoted
safely, and live-layer map extents are sent as query parameters
- Improved: all Databricks API calls use HTTPS
- Improved: clearer diagnostics in the QGIS log
- Improved: modern Qt6 code throughout, so one plugin runs natively on
QGIS 3 and QGIS 4
- Passes the QGIS plugin site security and Qt6 checks; tested on QGIS
3.44 and 4.2.3

1.5.0 - Genie One + Genie Agent rename
- New: Databricks Genie One dialog — ask questions across the whole
workspace
(no Genie Agent to pick) via the Genie One MCP server on Unity Gateway
- New: live progress steps, Cancel, multiple query results, Open in
Databricks link
- New: Genie One results with geometry can be added as map layers
- New: Genie charts shown inline in the chat for Genie Agent (Genie's
rendered image)
and Genie One (Genie One's chart spec, drawn natively); Save Chart as
PNG
- New: works with Personal Access Token and OAuth sign-in
- Changed: "Databricks Genie Chat" renamed to "Databricks Genie Agent"

1.4.0 - OAuth (browser login / SSO) authentication
- New: Auth Method selector — choose Personal Access Token or OAuth
(U2M)
- New: OAuth User-to-Machine browser sign-in; no Personal Access Token
required
- New: "Sign in" button primes the OAuth flow so the browser opens
only once
- New: OAuth tokens cached in a permission-restricted file under the
QGIS profile,
so connections, live-layer refreshes, the Browser panel and Genie
reuse them silently
- New: Genie REST calls obtain a bearer token from the cached OAuth
session
- Changed: all connections now flow through a single auth factory
(databricks_auth.py)
- Back-compat: existing Personal Access Token connections and layers
keep working unchanged

1.3.1 - Fix dependency installation on QGIS 4 macOS
- Fixed: thrift build failure caused by pip build isolation spawning
broken subprocess
- Fixed: "Couldn't load SIP module" error during dependency
installation
- Fixed: QGIS opening a second instance during pip install
- Added --no-build-isolation flag for in-process pip to prevent
subprocess spawning
- Added PYTHONPATH scrubbing to prevent QGIS paths leaking into build
subprocesses

1.3.0 - Genie Chat (natural language data queries)
- New: Databricks Genie Chat dialog — ask questions in plain English
- New: Genie Space browser with auto-populated space list
- New: Thinking indicator with animated dots, elapsed timer, and
Cancel button
- New: Smart geometry hints — instructs Genie to return geometry as a
typed column
- New: Collapsible SQL panel (hidden by default) with Show SQL / Copy
SQL buttons
- New: Markdown rendering for Genie responses (bold, italic, bullets,
code)
- New: Query results preview table (up to 100 rows)
- New: Auto-detect geometry columns and create QGIS layers from Genie
results
- New: Supports WKT and non-WKT geometry (auto-wraps with ST_ASWKT)
- New: Follow-up questions within the same Genie conversation
- New: Toolbar button and menu item for quick access
- New: Dark mode compatible — explicit text colours for readability
- New: Qt6 shims for QSizePolicy and QAbstractItemView enums

1.2.0 - Live layers + QGIS 4 / Qt6 compatibility
- New: Live Layer mode with viewport-based auto-refresh (pan/zoom to
load data)
- New: Mixed geometry detection for live layers (creates separate
layers per type)
- New: Auto-centre map on first live layer load
- New: Smart debounce and extent similarity checks to minimise queries
- New: Toggle live mode on/off via Plugins menu
- New: QGIS 4.0 (Qt6/PyQt6) support while maintaining QGIS 3.16+
compatibility
- New: Qt5/Qt6 compatibility shim module (_qt6_compat.py)
- Fixed: Plugin load failures caused by removed Qt5 unscoped enums
- Fixed: Dependency installation on QGIS 4 macOS (switched to
in-process pip)
- Fixed: Replaced deprecated exec_() with exec()
- Fixed: Hardcoded PyQt5 import replaced with portable qgis.PyQt
abstraction
