==Graphical environment==

===What's new===
* EiffelRibbon: a Windows specific library and tool to add a ribbon to your EiffelVision2 applications.
* Debian packages available for downloads
* Added external contributions: Decimal library, Json parser, arbitrary precision mathematics, encryption (SHA1, MD5, x509, ...)
* Added previews of libraries: sqlite3, regular expression, ...
* Added a command line option "-tests" to run all associated Autotest tests from the command line

===Improvements===
* Better integration to the latest Linux Desktop environments: Unity from Ubuntu and KDE 4.0.
* SCOOP speed improvements.
* Added support for .NET 4.0 runtime.

===Changes===
* BIT type is now obsolete.
* Location of precompiled libraries has been mode to a user specific directory that can be referenced via the $ISE_PRECOMP variable in your project configurations. This addresses some permission issues depending on how and under which user EiffelStudio was installed.

===Bug fixes===
* Fixed a display issue of Unicode characters when reporting an error. (bug#17661).
* Fixed a pick and drop issue where it could be confused (e.g. select ARRAY in editor, switch to clickable format, try to pick various elements, it would always pick BOOLEAN instead) (bug#17666)
* Fixed issue with pick and drop of a feature from an override class whose position is further away than the original class would not scroll to this feature (bug#17406).
* Fixed some issues of window positioning when using EiffelStudio with multiple monitors.
* Fixed a case where you could have 2 editor panes open on the same class.

==Libraries==

===EiffelBase===
* Prevented creation of instances of PROCEDURE, FUNCTION, and PREDICATE using a creation instruction. An agent has to be created via the agent expression provided at the language level.
* Fixed a potential reporting of version mismatch when there is a mismatch but actually no version changes.
* Added TABLE_ITERATOR and TABLE_ITERATION_CURSOR to provide a common way for TABLE like datastructure to iterate over using the new across loop.
* Improved speed of `replace_substring_all' when replacing a smaller string by a larger one.
* Added support for string searches of a STRING_32 string (previously it was limited to STRING_8).
* Fixed {IMMUTABLE_STRING_XX}.shared_substring which would not be properly processed by many string operations (e.g. item, item_code, code, ...)
* Changed the behavior of {STRING_XX}.twin to create a new string where the capacity is set to the count of the twined strings and not to its capacity. In scenarios where a large buffer is used but a frequent twin is used it has a big impact on speed and memory usage.
* Fixed an issue with {FILE}.read_to_string which would not change the hash_code of the string given as argument.
* Improved speed of HASH_TABLE lookups.
* Added <e>{POINTER}.is_default_pointer</e>.
* Excluded class <e>BIT_REF</e> from the default setup. In order to use type <e>BIT</e> one has to define a variable <code>USE_BIT</code>.

===EiffelVision2===
* [[Revisions and Bug Fixes|Click here for EiffelVision2 release notes.]]

* Added support for INTEGER_xx and NATURAL_xx datatypes.
* Added support for transactions in the MySQL handle.
