v0.14.1

Breaking changes

• Since most of the methods of Expr are now available for Series, the experimental <Series>$expr subnamespace is removed (#831). Use <Series>$<method> instead of <Series>$expr$<method>.

New features

• New active bindings $flags for DataFrame to show the flags used internally for each column. The output of $flags for Series was also improved and now contains FAST_EXPLODE for Series of type list and array (#809).
• Most of Expr methods are also available for Series (#819, #828, #831).
• as_polars_df() for data.frame is more memory-efficient and new arguments schema and schema_overrides are added (#817).
• Use polars_code_completion_activate() to enable code suggestions and autocompletion after $ on polars objects. This is an experimental feature that is disabled by default. For now, it is only supported in the native R terminal and in RStudio (#597).

Bug fixes

• <Series>$list sub namespace methods returns Series class object correctly (#819).
