########## _posts/2026-07-10-25.0.0-release.md: ########## Review Comment: ```suggestion ## R Notes ### Breaking changes - Arrow uint64 types are now always converted to R double (numeric) vectors, regardless of the values. Previously, small uint64 values were converted to R integer, which could cause inconsistent types within list columns when different list elements had different value ranges (#50339). ### New features - Field objects now support field-level metadata via $metadata and $with_metadata() (@max-romagnoli, #33390). - Parquet files now support list-columns of ordered factors (ordered dictionaries) (#49689). ### Minor improvements and fixes - Array$create() now gives a clearer error message when given a POSIXct object with an invalid timezone (#40886). - Dictionary arrays with large_string value types now convert correctly to R factors (#39603). - open_dataset() now gives a clearer error message when providing a mix of readr and Arrow options (@Rich-T-kid, #33420). - read_parquet() no longer triggers a C++ alignment warning from the Acero source node (#46178). - Schema metadata partial matching on $metadata$r no longer errors when other metadata keys start with “r” (#50163). - to_arrow() now preserves group_by() when converting from a dbplyr lazy table (#40640). - write_parquet() now correctly validates that max_rows_per_group is a positive number (#40742). - Stale S3 connections no longer cause a segfault during garbage collection (#50009). - Spurious “Invalid metadata$r” warnings are no longer emitted when reading files with custom schema metadata (#48712). ### Installation - The R package now builds under r-universe/r-wasm (#49981). ``` -- This is an automated message from the Apache Git Service.
