+# Change Log
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](http://keepachangelog.com/)
+and this project adheres to [Semantic Versioning](http://semver.org/).
+
+## [Unreleased][HEAD]
+
+## [3.0.0] - 2021-07-30
+
+The decoder is in sync with ArcMap 10.8.1 and ArcGIS Pro 2.8. LERC encoded binary blobs from any previous version of ArcMap or ArcGIS Pro can also be read / decoded.
+
+### Added
+* Added an option to return decoded n-dim blob using pixel-interleaved layout
+
+### Changed
+* Upgrade Lerc codec to new version Lerc 2.5.
+
+## [2.0.0] - 2018-11-06
+
+The decoder is in sync with ArcMap 10.7 and ArcGIS Pro 2.3. LERC encoded binary blobs from any previous version of ArcMap or ArcGIS Pro can also be read / decoded.
+
+### Added
+* Extend from one value per pixel to nDim values per pixel.
+
+### Changed
+* Upgrade Lerc codec to new version Lerc 2.4.
+
+## 1.0.1 - 2017-02-18
+
+### Fixed
+
+* resolved a Huffman code table parsing issue [#31](https://github.com/Esri/lerc/pull/31)
+
+## 1.0 - 2016-11-30
+
+This LERC API JavaScript decoder is in sync with ArcMap 10.5 and ArcGIS Pro 1.4. LERC encoded binary blobs from any previous version of ArcMap or ArcGIS Pro can be read / decoded as well.
+
+### What will trigger a major version change
+
+- A change to this LERC API that is not backwards compatible and requires users to update / change their code in order to use an upgraded .dll or .so file.
+- A change to the LERC bitstream that is not backwards compatible and requires users to upgrade their LERC encoder and / or decoder.

+
+### decode(input, [options]) ⇒ <code>Object</code> ⏏
+A wrapper for decoding both LERC1 and LERC2 byte streams capable of handling multiband pixel blocks for various pixel types.
+
+**Kind**: Exported function
+
+| Param | Type | Description |
+| --- | --- | --- |
+| input | <code>ArrayBuffer</code> | The LERC input byte stream |
+| [options] | <code>object</code> | The decoding options below are optional. |
+| [options.inputOffset] | <code>number</code> | The number of bytes to skip in the input byte stream. A valid Lerc file is expected at that position. |
+| [options.pixelType] | <code>string</code> | (LERC1 only) Default value is F32. Valid pixel types for input are U8/S8/S16/U16/S32/U32/F32. |
+| [options.noDataValue] | <code>number</code> | (LERC1 only). It is recommended to use the returned mask instead of setting this value. |
+
+**Result Object Properties**
+
+| Name | Type | Description |
+| --- | --- | --- |
+| width | <code>number</code> | Width of decoded image. |
+| height | <code>number</code> | Height of decoded image. |
+| pixels | <code>array</code> | [band1, band2, …] Each band is a typed array of width*height. |
+| pixelType | <code>string</code> | The type of pixels represented in the output. |
+| mask | <code>mask</code> | Typed array with a size of width*height, or null if all pixels are valid. |
+| statistics | <code>array</code> | [statistics_band1, statistics_band2, …] Each element is a statistics object representing min and max values |
