+```
+
+## 0.9.0 (2017-03-09)
+
+* Removed ods.js source.  The xlsx.js source absorbed the ODS logic and exposes
+  the ODS variable, so projects should remove references to ods.js

+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+
+      You may add Your own copyright statement to Your modifications and

+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

-# xlsx
+# [SheetJS](https://sheetjs.com)
 
-Currently a parser for XLSX/XLSM/XLSB files.  Cleanroom implementation from the
-ISO 29500  Office Open XML specifications, [MS-XLSB], and related documents.
+The SheetJS Community Edition offers battle-tested open-source solutions for
+extracting useful data from almost any complex spreadsheet and generating new
+spreadsheets that will work with legacy and modern software alike.
 
-## Installation
+[SheetJS Pro](https://sheetjs.com/pro) offers solutions beyond data processing:
+Edit complex templates with ease; let out your inner Picasso with styling; make
+custom sheets with images/graphs/PivotTables; evaluate formula expressions and
+port calculations to web apps; automate common spreadsheet tasks, and much more!
 
-In node:
+## Documentation
 
-    npm install xlsx
+- [API and Usage Documentation](https://docs.sheetjs.com)
 
-In the browser:
+- [Downloadable Scripts and Modules](https://cdn.sheetjs.com)
 
-    <!-- JSZip must be included before xlsx.js -->
-    <script lang="javascript" src="/path/to/jszip.js"></script>
-    <script lang="javascript" src="/path/to/xlsx.js"></script>
+## Constellation
 
-## Usage
+- <https://oss.sheetjs.com/notes/>: File Format Notes
 
-Simple usage (walks through every cell of every sheet and dumps the values):
+- [`ssf`](packages/ssf): Format data using ECMA-376 spreadsheet format codes
 
-    var XLSX = require('xlsx')
-    var xlsx = XLSX.readFile('test.xlsx');
-    var sheet_name_list = xlsx.SheetNames;
-    xlsx.SheetNames.forEach(function(y) {
-      for (z in xlsx.Sheets[y]) {
-        if(z[0] === '!') continue;
-        console.log(y + "!" + z + "=" + JSON.stringify(xlsx.Sheets[y][z].v));
-      }
-    });
+- [`xlsx-cli`](packages/xlsx-cli): NodeJS command-line tool for processing files
 
-The node version installs a binary `xlsx2csv` which can read XLSX/XLSM/XLSB files and output the contents in various formats.  The source is available at `xlsx2csv.njs` in the bin directory.
+- [`cfb`](https://git.sheetjs.com/SheetJS/js-cfb): Container (OLE/ZIP) file
+processing library
 
-See <http://oss.sheetjs.com/js-xlsx/> for a browser example.
+- [`codepage`](https://git.sheetjs.com/SheetJS/js-codepage): Legacy text
+encodings for XLS and other legacy spreadsheet formats
 
-Note that older versions of IE does not support HTML5 File API, so the base64 mode is provided for testing.  On OSX you can get the base64 encoding by running:
+- [`dta`](packages/dta): Stata DTA file processor
 
-    $ <target_file.xlsx base64 | pbcopy # the pbcopy puts the content in the clipboard
-
-Some helper functions in `XLSX.utils` generate different views of the sheets:
-
-- `XLSX.utils.sheet_to_csv` generates CSV
-- `XLSX.utils.sheet_to_row_object_array` interprets sheets as tables with a header column and generates an array of objects
-- `XLSX.utils.get_formulae` generates a list of formulae
-
-For more details:
-
-- `bin/xlsx2csv.njs` is a tool for node
-- `index.html` is the live demo
-- `bits/90_utils.js` contains the logic for generating CSV and JSON from sheets
-
-## Cell Object Description
-
-`.SheetNames` is an ordered list of the sheets in the workbook
-
-`.Sheets[sheetname]` returns a data structure representing the sheet.  Each key
-that does not start with `!` corresponds to a cell (using `A-1` notation).
-
-`.Sheets[sheetname][address]` returns the specified cell:
-
-- `.v` : the raw value of the cell
-- `.w` : the formatted text of the cell (if applicable)
-- `.t` : the type of the cell (constrained to the enumeration `ST_CellType` as documented in page 4215 of ISO/IEC 29500-1:2012(E) )
-- `.f` : the formula of the cell (if applicable)
-- `.r` : the rich text encoding of a cell text (if applicable)
-- `.h` : an HTML rendering of the rich text (if applicable)
-- `.c` : comments associated with the cell
-- `.z` : the number format string associated with the cell (if requested)
-
-For dates, `.v` holds the raw date code from the sheet and `.w` holds the text
-
-## Options
-
-The exported `read` and `readFile` functions accept an options argument:
-
-| Option Name | Default | Description |
-| :---------- | ------: | :---------- |
-| cellFormula | true    | Save formulae to the .f field ** |
-| cellHTML    | true    | Parse rich text and save HTML to the .h field |
-| cellNF      | false   | Save number format string to the .z field |
-| sheetStubs  | false   | Create cell objects for stub cells |
-| bookDeps    | false   | If true, parse calculation chains |
-| bookProps   | false   | If true, only parse enough to get book metadata ** |
-| bookSheets  | false   | If true, only parse enough to get the sheet names |
-
-- `cellFormula` only applies to constructing XLSB formulae.  XLSX/XLSM formulae
-  are stored in plaintext, but XLSB formulae are stored in a binary format.
-- Even if `cellNF` is false, formatted text (.w) will be generated
-- In some cases, sheets may be parsed even if `bookSheets` is false.
-- `bookSheets` and `bookProps` combine to give both sets of information
-- `Deps` will be an empty object if `bookDeps` is falsy
-
-The defaults are enumerated in bits/84_defaults.js
-
-## Tested Environments
-
- - Node 0.8.14, 0.10.1
- - IE 6/7/8/9/10 using Base64 mode (IE10 using HTML5 mode)
- - FF 18 using Base64 or HTML5 mode
- - Chrome 24 using Base64 or HTML5 mode
-
-Tests utilize the mocha testing framework.  Travis-CI and Sauce Labs links:
-
- - <https://travis-ci.org/SheetJS/js-xlsx> for XLSX module in node
- - <https://travis-ci.org/SheetJS/SheetJS.github.io> for XLS* modules
- - <https://saucelabs.com/u/sheetjs> for XLS* modules using Sauce Labs
-
-## Test Files
-
-Test files are housed in [another repo](https://github.com/SheetJS/test_files).
-
-## Testing
-
-`make test` will run the node-based tests.  To run the in-browser tests, clone
-[the oss.sheetjs.com repo](https://github.com/SheetJS/SheetJS.github.io) and
-replace the xlsx.js file (then fire up the browser and go to `stress.html`):
-
-```
-$ cp xlsx.js ../SheetJS.github.io
-$ cd ../SheetJS.github.io
-$ simplehttpserver # or "python -mSimpleHTTPServer" or "serve"
-$ open -a Chromium.app http://localhost:8000/stress.html
-```
-
-## Contributing
-
-Due to the precarious nature of the Open Specifications Promise, it is very important to ensure code is cleanroom.  Consult CONTRIBUTING.md
-
-## XLS Support
-
-XLS is available in [js-xls](https://github.com/SheetJS/js-xls).
+- [`test_files`](https://github.com/sheetjs/test_files): Test files and various
+plaintext baselines.
