3.0.0 (2022-04-25)

⚠ BREAKING CHANGES

• ir: The following are breaking changes due to simplifying expression internals
  • ibis.expr.datatypes.DataType.scalar_type and DataType.column_type factory
    methods have been removed, DataType.scalar and DataType.column class
    fields can be used to directly construct a corresponding expression instance
    (though prefer to use operation.to_expr())
  • ibis.expr.types.ValueExpr._name and ValueExpr._dtype`` fields are not accassible anymore. While these were not supposed to used directly now ValueExpr.has_name(), ValueExpr.get_name()andValueExpr.type()` methods
    are the only way to retrieve the expression's name and datatype.
  • ibis.expr.operations.Node.output_type is a property now not a method,
    decorate those methods with @property
  • ibis.expr.operations.ValueOp subclasses must define output_shape and
    output_dtype properties from now on (note the datatype abbreviation dtype
    in the property name)
  • ibis.expr.rules.cast(), scalar_like() and array_like() rules have been
    removed
• api: Replace t["a"].distinct() with t[["a"]].distinct().
• deps: The sqlalchemy lower bound is now 1.4
• ir: Schema.names and Schema.types attributes now have tuple type rather than list
• expr: Columns that were added or used in an aggregation or
  mutation would be alphabetically sorted in compiled SQL outputs. This
  was a vestige from when Python dicts didn't preserve insertion order.
  Now columns will appear in the order in which they were passed to
  aggregate or mutate
• api: dt.float is now dt.float64; use dt.float32 for the previous behavior.
• ir: Relation-based execute_node dispatch rules must now accept tuples of expressions.
• ir: removed ibis.expr.lineage.{roots,find_nodes} functions
• config: Use ibis.options.graphviz_repr = True to enable
• hdfs: Use fsspec instead of HDFS from ibis
• udf: Vectorized UDF coercion functions are no longer a public API.
• The minimum supported Python version is now Python 3.8
• config: register_option is no longer supported, please submit option requests upstream
• backends: Read tables with pandas.read_hdf and use the pandas backend
• The CSV backend is removed. Use Datafusion for CSV execution.
• backends: Use the datafusion backend to read parquet files
• Expr() -> Expr.pipe()
• coercion functions previously in expr/schema.py are now in udf/vectorized.py
• api: materialize is removed. Joins with overlapping columns now have suffixes.
• kudu: use impala instead: https://kudu.apache.org/docs/kudu_impala_integration.html
• Any code that was relying implicitly on string-y
  behavior from UUID datatypes will need to add an explicit cast first.
