# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).

## [0.7.3]
### Added
 - Export query/scan/parallelScan iterator and paginator classes.

## [0.7.2]
### Fixed
 - Sort key configurations in `CreateTableInput` so that hash keys always appear
    first.

## [0.7.1]
### Removed
 - Remove package rollup at `./build/index.mjs` due to bundler incompatibilities.

## [0.7.0]
### Added
 - Add a package rollup at `./build/index.mjs` to support tree shaking.

## [0.6.0]
### Fixed
 - Update `query` and `scan` to serialize whatever key properties are provided
    without injecting any defaulted values.
 - Update `DataMapper` for TypeScript 2.9 compatibility.

### Added
 - Use purpose-built async iterable objects as the return value for `query`,
    `scan`, and `parallelScan`.
 - Report the `count`, `scannedCount`, and `consumedCapacity` tallied over the
    lifetime of a `query`, `scan`, or `parallelScan` as properties on the
    returned iterable.
 - Provide a method to get the underlying paginator for a `query`, `scan`, or
    `parallelScan` iterator. The paginator may be used to suspend and resume
    iteration at any page boundary.
 - Add `limit` parameter to `scan` and `query` to automatically cease iteration
    once a certain number of items have been returned or the results have been
    exhausted, whichever comes first.

## [0.5.0]
### Fixed
 - Add default message to `ItemNotFoundException`
 - Ensure options provided are used when `query` is called with a named
    parameter bag.
### Added
 - Add support for executing custom update expressions.

## [0.4.2]
### Fixed
 - Ensure `query` and `scan` marshall exclusive start keys for the specified
    index.

## [0.4.1]
### Fixed
 - Ensure `query` returns instances of the provided model class.

## [0.4.0]
### Added
 - Add `createTable` to create tables based on table names and schemas bound to
    constructor prototypes
 - Add `ensureTableExists` to create a table only if it does not already exist
 - Add `deleteTable` to delete tables based on table names bound to constructor
    prototypes
 - Add `ensureTableNotExists` to delete a table only if it is not already
    deleted

## [0.3.2]
### Fixed
 - Only include expression name or value substitions when a substitution has
    occurred

## [0.3.1]
### Fixed
 - Ensure retried writes in a `batchDelete`, `batchPut`, or `batchWrite` are
    only yielded once

## [0.3.0]
### Added
 - Add `batchGet`, which allows a synchronous or asynchronous iterable of items
    (like those supplied to `get`) to be automatically grouped into
    `BatchGetItem` operations.
 - Add `batchDelete`, which allows a synchronous or asynchronous iterable of
    items (like those supplied to `delete`) to be automatically grouped into
    `BatchWriteItem` operations.
 - Add `batchPut`, which allows a synchronous or asynchronous iterable of
    items (like those supplied to `put`) to be automatically grouped into
    `BatchWriteItem` operations.
 - Add `batchWrite`, which allows a synchronous or asynchronous iterable of
    tuples of tags (`'put'` or `'delete'`) and items (like those supplied to the
    `put` or `delete` methods, respectively) to be automatically grouped into
    `BatchWriteItem` operations.

## [0.2.1]
### Added
 - Add the ability to call all DataMapper methods with positional rather than
    named parameters
 - Add API documentation

### Deprecated
 - Deprecate calling DataMapper methods with a single bag of named parameters

## [0.2.0]
### Removed
 - **BREAKING CHANGE**: Removed the `returnValues` parameter from `put`. `put`
    will now always return the value that was persisted, thereby providing
    access to injected defaults and accurate version numbers.

### Added
 - Add a `parallelScan` method to the DataMapper.
 - Add optional parameters to the `scan` method to allow its use as a parallel
    scan worker
 - Add a `pageSize` parameter to `query` and `scan` to limit the size of pages
    fetched during a read. `pageSize` was previously called `limit`.

### Changed
 - Use TSLib instead of having TypeScript generate helpers to reduce bundle size

### Deprecated
 - Deprecate `limit` parameter on `query` and `scan`. It has been renamed to
    `pageSize`, though a value provided for `limit` will still be used if no
    `pageSize` parameter is provided.

## [0.1.1]
### Fixed
 - Update dependency version to match released version identifier

## [0.1.0]
Initial release
