   ## Go notes
   
   ### Security
   
   * Updated testify dependency to address CVE-2022-28948. ([ARROW-16759](https://issues.apache.org/jira/browse/ARROW-16759)) (This was also backported to previous versions and released as patch versions v6.0.2, v7.0.1, and v8.0.1)
   
   ### Arrow
   
   #### New Features
   
   * Dictionary Scalars are now available ([ARROW-16323](https://issues.apache.org/jira/browse/ARROW-16323))
   * Introduced a DictionaryUnifier object along with functions for unifying Chunked Arrays and Tables ([ARROW-16324](https://issues.apache.org/jira/browse/ARROW-16324))
   * New CSV examples added to documentation to demonstrate error handling ([ARROW-16450](https://issues.apache.org/jira/browse/ARROW-16450))
   * CSV Reader now supports arrow.TimestampType ([ARROW-16504](https://issues.apache.org/jira/browse/ARROW-16504))
   * JSON parsing for Temporal Types now allow passing numeric values in addition to strings for parsing. Timezones will be properly parsed if they exist in the string and a function was added to retrieve a time.Location object from a TimestampType ([ARROW-16551](https://issues.apache.org/jira/browse/ARROW-16551))
   * New utilities added to decimal128 for rescaling and easy conversion to and from float32/float64 ([ARROW-16552](https://issues.apache.org/jira/browse/ARROW-16552))
   * Arrow DataType interface now has a LayoutMethod which returns the physical layout of the given datatype such as the number of buffers, types, etc. This matches the behavior of the layout() methods in C++ for data types. ([ARROW-16556](https://issues.apache.org/jira/browse/ARROW-16556))
   * Added a SliceBuffer function to the memory package to allow better re-using of memory across buffer objects ([ARROW-16557](https://issues.apache.org/jira/browse/ARROW-16557))
   * Dictionary Arrays can now be concatenated using array.Concatenate ([ARROW-17095](https://issues.apache.org/jira/browse/ARROW-17095))
   
   #### Bug Fixes 
   
   * ipc.FileReader now properly uses the memory.Allocator interface ([ARROW-16002](https://issues.apache.org/jira/browse/ARROW-16002))
   * Addressed issue with Integration tests between Go and Java ([ARROW-16441](https://issues.apache.org/jira/browse/ARROW-16441))
   * RecordBuilder.UnmarshalJSON now properly ignores extra unknown fields rather than panic'ing ([ARROW-16456](https://issues.apache.org/jira/browse/ARROW-16456))
   * StructBuilder.UnmarshalJSON will no longer fail and panic when Nullable fields are missing ([ARROW-16502](https://issues.apache.org/jira/browse/ARROW-16502))
   * ipc.Reader no longer silently accepts string columns with invalid offsets, preventing unexpected panics later when writing or accessing the resulting arrays. ([ARROW-16831](https://issues.apache.org/jira/browse/ARROW-16831))
   * Arrow CSV reader no longer clobbers its reported errors and properly surfaces them ([ARROW-16926](https://issues.apache.org/jira/browse/ARROW-16926))
   
   ### Parquet
   
   #### New Features
   
   * The CreatedBy version string for the Parquet writer will now correctly reflect the library version, and will be updated by the release scripts ([ARROW-16484](https://issues.apache.org/jira/browse/ARROW-16484))
   * Parquet bit_packing functions now have ARM64 NEON implementations for performance ([ARROW-16486](https://issues.apache.org/jira/browse/ARROW-16486))
   * It is now possible to customize the root node in the Parquet writer instead of hardcoding it to be named "schema" with a repetition type of Repeated. This was needed to allow producing files similar to spark where the root node has a repetition type of Required. It still defaults to the spec definition of Repeated. ([ARROW-16561](https://issues.apache.org/jira/browse/ARROW-16561))
   * parquet_reader CLI mainprog has been enhanced to dump values out as JSON and CSV along with setting an output file instead of just dumping to the terminal. ([ARROW-16934](https://issues.apache.org/jira/browse/ARROW-16934))
   
   #### Bug Fixes
   
   * Fixed a memory leak with Parquet page reading ([ARROW-16473](https://issues.apache.org/jira/browse/ARROW-16473))
   * Parquet Reader properly parallelizes column reads when the parallel option is set to true. ([ARROW-16530](https://issues.apache.org/jira/browse/ARROW-16530))
   * Fixed bug in the Bool decoder for plain encoding ([ARROW-16563](https://issues.apache.org/jira/browse/ARROW-16563))
   * Fixed a bug in the Parquet bool column reader where it failed to properly skip rows ([ARROW-16638](https://issues.apache.org/jira/browse/ARROW-16638))
   * Fixed the flakey travis ARM64 builds by reducing the size of a test case in the pqarrow unit tests to reduce the memory usage for the tests. ([ARROW-16669](https://issues.apache.org/jira/browse/ARROW-16669))
   * Parquet writer now properly handles writing arrow.NULL type arrays ([ARROW-16749](https://issues.apache.org/jira/browse/ARROW-16749))
   * Column level dictionary encoding configuration for Parquet writing now correctly respects the input value ([ARROW-16813](https://issues.apache.org/jira/browse/ARROW-16813))
   * Memory leak in DeltaByteArray encoding fixed ([ARROW-16983](https://issues.apache.org/jira/browse/ARROW-16983))
