v1.0.0

New features:

* Add support for naive Decimal128 decoding
* Add support for decoding timestamps from Decimal, so [the full range of ORC timestamps](https://github.com/datafusion-contrib/datafusion-orc/pull/96) is supported
* Add support for decoding dictionary-encoded with primitive values

Changes:

* Update from arrow v50 to v52

Fixes:

* ar_row_derive: Use fully-qualified names to avoid shadowing
* Fix error message on missing columns

v0.6.0

This release forks `orcxx` into a new crate, `ar_row` aimed at providing row-oriented
deserialization of Apache Arrow arrays, by reusing `orcxx`'s deserialization architecture,
traits, and `derive` macro.

This removes all ORC-specific code, except for tests (which now use `datafusion-orc`
to read data files into Arrow structures); and all C++ code.

v0.5.0

* Compile with `-fPIC` to fix some linking issues
* Fix tests
* Add `ORC_USE_SYSTEM_LIBRARIES` env var to use system libraries instead of downloading
* Display nicer error messages when CMake or Make returns an error

v0.4.2

Fixes:

* Fix decoding of timestamps, they are not a single i64 as I thought

v0.4.0

Breaking:

* Use `thiserror` instead of nested `Result`
* Rename 'utils' module to 'errors'

Additions:

* Add support for deserializing Timestamp as i64 struct field

Internal:

* Replace `unsafe_unwrap` with stdlib's `unwrap_unchecked`

v0.3.0

Breaking:

* Make `Reader::row_reader()` take a ref instead of owned RowReaderOptions

Additions:

* Add ParallelRowIterator
* Implement ExactSizeIterator and DoubleEndedIterator for RowIterator
* Implement `row_number()` and `seek_to_row()` for RowReader
* Impl Sync and Clone for RowReaderOptions
* Implement Send for vectors

Fixes:

* Fix empty list deserialization

Internal:

* `orcxx_derive/tests/test1.rs`: Test more batch sizes (+deduplicate)

v0.2.3

Documentation:

* Avoid relative links between crate documentation

v0.2.2

Documentation:

* Copy examples to the README
* Add links between documentation pages

Internal:

* Add pre-commit config
* Remove orcxx/README.md symlink

v0.2.1

Documentation:

* `orcxx_derive`: Document RowIterator with an example

Internal:

* Use system libraries when building on docs.rs

v0.2.0

Breaking:

* RowIterator: Always check the selected kind
* Simplify RowIterator::new() to automatically select columns

Additions:

* `OrcStruct::columns()`
* Support for escaping field names

Internal:

* Fix dependencies between crates + dedup metadata

v0.1.0

Initial release.

Provides full read-only access to .orc files through three APIs:

* trees of vectors
* vectors of rows (structures generated with a custom derive)
* iterator on rows (ditto)
