# Apache Cassandra - Change log

# v3.0.0

## 3.3.0

### Minor Changes

- 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.

## 3.2.0 (2026.02.22)

### Minor Changes

- **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](https://github.com/HadesArchitect/GrafanaCassandraDatasource/blob/main/docs/variables.md)). (issue #182) - Thanks @HadesArchitect

### Patch Changes

- **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
