[Unreleased]

Add cell delimiters and code lens actions to the Positron extension (#366)
ODBC is now turned on for the CLI as well (#344)
FROM can now come before VISUALIZE, mirroring the DuckDB style. This means that FROM table VISUALIZE x, y and VISUALIZE x, y FROM table are equivalent queries (#369)
CLI now has built-in documentation through the docs command as well as a skill for llms through the skill command (#361)

Rendering of inline plots in Positron had a bad interaction with how we handled auto-resizing in the plot pane. We now have a per-output-location path in the Jupyter kernel (#360)
Passing the shape aesthetic via SETTING now correctly translates named shapes (#368)
Asterisk shape now has lines 60 degrees apart, giving an even shape
validate() now reports an actionable error when a SQL expression (e.g. CAST(...) or a function call) appears inside a VISUALISE mapping, instead of silently treating the entire query as SQL (#389)
Error messages no longer leak internal aesthetic names. Validation, scale, and writer errors now report user-facing aesthetic names (x, y, panel, row, …) instead of internal forms (pos1, pos2, facet1, …), translated based on the active coordinate system and facet layout (#388).
Fixed opacity calculation in point layers with Vega-Lite (#393)
Fixed an issue with case-sensitive column references in mappings (#374)
Fixed an issue with OOB null-filtering, leading to missing median lines in boxplots (#394)

Reverted an earlier decision to materialize CTEs and the global query in Rust before registering them back to the backend. We now keep the data purely on the backend until the layer query as was always intended (#363)
Relieved some grammatical constraints on the SQL-portion before the VISUALISE portion (#364).
Simplified internal approach to DataFrame with DuckDB reader (#365)
Moved the CLI to its own module rather than be part of the main crate (#379)
Restructured CLAUDE.md to better deal with the rising complexity of the project (#382)
Renamed the errorbar layer to range. The geom was never error-specific and is generally useful for displaying intervals (min/max ranges, candlestick wicks, percentile bands, etc.).
The segment layer now requires both xend and yend (rather than auto-filling a missing endpoint from the start position). For axis-aligned 1D intervals — lollipops, candlestick wicks, etc. — use the range layer instead.

Removed polars from dependency list along with all its transient dependencies. Rewrote DataFrame struct on top of arrow (#350)
Moved ggsql-python to its own repo (posit-dev/ggsql-python) and cleaned up any additional references to it
Moved ggsql-r to its own repo (posit-dev/ggsql-r)
