  * [#80](https://github.com/magento/magento2/issues/80) -- fixed some runtime errors in import/export module
  * [#81](https://github.com/magento/magento2/issues/81) -- removed usage of "remove" directive in places where it is overridden by setting root template anyway
  * [#87](https://github.com/magento/magento2/issues/87) -- changed paths of files to include from relative into absolute in `dev/shell/indexer.php` and `log.php`
  * [#88](https://github.com/magento/magento2/issues/88) -- provided comments for values that can be configured in `app/etc/local.xml` file
  * [#90](https://github.com/magento/magento2/issues/90) -- slightly optimized logic of implementation of loading configurable product attributes

* Refactored ACL for the backend
  * ACL resources
    * Strict configuration format, validated by XSD schema
    * ACL configuration relocation from `app/code/<pool>/<namespace>/<module>/etc/adminhtml.xml` to `app/code/<pool>/<namespace>/<module>/etc/adminhtml/acl.xml`
    * Renamed ACL resource identifiers according to the format `<namespace>_<module>::<resource>` throughout the system
      * Backend menu configuration requires to specify ACL resource identifier in the new format
      * Explicit declaration of ACL resources in `app/code/<pool>/<namespace>/<module>/etc/system.xml` instead of implicit relation by XPath
    * Migration tool `dev/tools/migration/acl.php` to convert ACL configuration from 1.x to 2.x
  * Declaration of ACL resource/role/rule loaders through the area configuration
    * Module `Mage_Backend` declares loader for ACL resources in backend area
    * Module `Mage_User` declares loaders for ACL roles and rules (relations between roles and resources) in backend area
  * Implemented integrity and legacy tests for ACL
* Fixed issues:
  * Losing qty and visibility information when importing products
  * Impossibility to reload captcha on backend
  * Temporary excluded from execution integration test `Mage_Review_Model_Resource_Review_Product_CollectionTest::testGetResultingIds()` and corresponding fixture script, which cause occasional `segmentation fault` (exit code 139)
* Refactored methods with high cyclomatic complexity:
  * `Mage_Adminhtml_Block_System_Store_Edit_Form::_prepareForm()`
  * `Mage_Adminhtml_Block_System_Config_Form::initForm()`
  * `Mage_Adminhtml_Block_System_Config_Form::initFields()`
* GitHub requests:
  * [#32](https://github.com/magento/magento2/pull/32) -- fixed declaration of localization CSV files
  * [#35](https://github.com/magento/magento2/issues/35) -- removed non-used `Mage_Core_Block_Flush` block
  * [#41](https://github.com/magento/magento2/pull/41) -- implemented ability to extends `app/etc/local.xml` by specifying additional config file via `MAGE_LOCAL_CONFIG` environment variable

- Added jQuery to Magento 2. It has not been made a main library yet, however all new features are developed using jQuery.
- Added support for new versions of testing tools - PHPUnit 3.6, PHPMD 1.3.0. Confirmed compatibility with latest PHPCS 1.3.2 and PHPCPD 1.3.5.
- Improved legacy tests:
-- Refactored Integrity_ClassesTest and Legacy_ClassesTest.
-- Implemented a tool for migrating factory names from 1.x to 2.x. The tool scans PHP-code and replaces the most "popular" cases.
-- Added tests for "//model" in config.xml files and "//*[@module]" in all xml files.
-- Implemented a test that verifies the absence of relocated directories.
-- Added a test against the obsolete Varien_Profiler.
- Bug fixes:
-- Fixed phpdoc for Mage_Core_Model_Design_Package.
-- Fixed static code analysis failures related to case-sensitivity.
-- Fixed several typos and minor mistakes.
-- Fixed integration test's failures due to specifics of xpath library version.
- Imported fresh features and bug fixes from Magento 1.x.
