v3.0.0

3.3.0

066f577: Added support for Cassandra clusters that use non-standard authenticators (e.g. LDAP). Previously, connecting to such clusters would fail during the initial handshake with an unexpected authenticator error.

A new Allowed authenticators field in the connection settings lets you specify which authenticator class names the driver should accept, as a semicolon-separated list. Leaving it empty preserves the original behaviour, so existing data sources are unaffected.

Added variable interpolation support for chained/dependent variables - Variable queries now support template variable interpolation using ${variable} syntax, enabling powerful cascading variable dependencies. Users can now create hierarchical variable relationships (e.g., Zone → Location → Sensor) where selecting a value in one variable automatically filters options in dependent variables (see Variables documentation). (issue #182) - Thanks @HadesArchitect

Improved UI with query mode switcher and contextual documentation links - Replaced the plain "Toggle editor mode" button with a RadioButtonGroup (Configurator / Query Editor) for a clearer mode-switching experience and linked relevant docs page (configurator or editor) and GitHub Discussions.
Added support for Cassandra VARINT columns (#235) - Querying a table with a varint column caused the plugin to crash with field value has unsupported type *big.Int. Cassandra's varint type is an arbitrary-precision integer backed by Go's *big.Int, which was not handled during row normalisation. The fix adds explicit conversion of *big.Int values so that varint columns are returned as numeric data instead of producing an error. (issue #235) - Thanks @HadesArchitect and @arturngomes
Fix ConfigEditor - stop mutating React props directly instead of using proper state updates (issue #230) - Thanks @hugohaggmark
