+- Fixed a bug where `event_table_telemetry` is using incorrect resource attributes.
+- Fixed a bug where `value_contains_null` was not propagated for `MapType` in `_as_nested` function.
 - Fixed a bug where CTE optimization incorrectly deduplicated subtrees containing non-deterministic data generation functions (e.g. `uuid_string()`). 
 - Fixed a bug where vectorized UDFs using non-anaconda package repositories did not specify the pandas package by default.

 - Fixed a bug where `Session.create_dataframe` raised `TypeError` when a `StringType` column was given a non-string Python value (e.g. `int`, `float`, `bool`, `Decimal`) for a small local relation (below the array bind threshold); `VALUES` SQL generation now coerces these types to string literals, consistent with the large-data bind-parameter path.
 - Fixed a bug where `DataFrame.approxQuantile` did not accept a `Column` for the `col` parameter.
-- Fixed a bug where `event_table_telemetry` is using incorrect resource attributes.
-- Fixed a bug where `value_contains_null` was not propagated for `MapType` in `_as_nested` function.
 
 ### Snowpark Local Testing Updates
 
 #### Bug Fixes
 
 - Fixed a bug where `concat` produced extra NaN rows and mismatched values after a `filter` operation in local testing.
-- Fix a bug where `dense_rank()` would fail with `ValueError` on NULL partition values.
-- Fixed a bug where `collect()` raised `KeyError` after `save_as_table(column_order="name")` when the source DataFrame omitted columns of `VariantType`, `MapType`, or `ArrayType` present in the target table schema in local testing.
