==What's new==
* Added support for agents with targets of separate types.
* Added new levels of void-safety: "conformance" that enables taking attachment marks into account when checking for conformance; "transitional" (previously "all") that checks almost all void-safety rules except those for unqualified agents and allows CAPs for preconditions and check instructions; "all" that checks all void-safety rules.
==Improvements==
* Fixed issue that causes many classes to be recompiled when not needed.
* Relaxed rules for using Current and unqualified agents when not all attributes are set to report VEVI errors only when qualified calls are involved in a sequence of unqualified calls and creation procedure calls ("targeted rules").
==Changes==
* The BIT type has been completely removed from libraries and runtime.
==Bug fixes==
===Language issues===
N/A
===Compiler issues===
* Fixed error in processing replicated and selected attributes with self-initializing attribute bodies that could lead to reporting these attributes as uninitialized.
* Fixed a bug that might result in a missing VEVI error for Result in a self-initializing attribute body.
===SCOOP issues===
* Fixed a bug that caused incorrect conformance checks for formal generics of different separate status.
* Fixed a bug that might cause incorrect conformance checks for attachment and separateness status of a constrained formal generic parameter against a class type.
* Fixed a C code generation bug that might cause an access on an invalid address during object test evaluation with an expression of a separate type.
===Runtime/code generation issues===
* Fixed a bug where the TYPE instance of a new generic derivation in the running system would be corrupted.
===Store/Retrieve issues===
* Fixed a bug in .NET where using the Eiffel serialization or marking objects would trigger computation of `hash_code' on Eiffel objects and thus changing their state.

[[Image:information tool change analysis]]
Within EiffelStudio 7.3, there will be new functions in Infomation tool to track changes on target or external resouce side, and potentially affected items on either side are listed.
The information tool can track changes in an Eiffel system or external resources side, and potentially affected items on either side are listed.
== Major Features ==
* '''Affected target:''' List of elements of current system that would be affected by external resource changes. (External resource is limited to local files.)
* '''Affected source:''' List of external resources that might be affected by changes of current system. (No limit of the type of external resources)
* '''Change acknowledgement:''' Acknowledgement of the changes that are aware of and will be ignored without any further actions.
* '''Affected target:''' List of elements of the Eiffel system that would be affected by a change in external resources.
* '''Affected source:''' List of external resources that might be affected by changes in the Eiffel system.
* '''Change acknowledgement:''' Acknowledgement of the changes which will be ignored with no further actions.
== Typical Work Flows ==
=== Affected external resources caused by current system change ===
# Open a class, add an Information entry with an external source in the class.
=== Affected external resources caused by a change in the Eiffel system ===
# Open a class, add an Information entry with an external resource in the class.
# Start working on that class, save it at as you normally do on regular basis.
# Open Info tool, go to Affected source item in the left tree.
# Check the list of external resouces that might be affected by last changes, as shown in the sceen cast bellow.
# Acknowledge the changes if you find that the external resources do not need a change for last changes of current system.
# Open the information tool, go to Affected source item in the left tree.
# Check the list of external resources that might be affected by last changes.
# Acknowledge the changes once you have updated the external resource accordingly (possibly no change is required in the case of simple system changes).
=== Affected items in the Eiffel system caused by an external resource change ===
# Open a class, add an Information entry with an external resource in the class.
# Start working on that external resource, save it at as you normally do on regular basis.
# Open the information tool, go to Affected target in the left tree.
# Check the list of classes that might be affected by last changes of the external resource. (You may need to click on the "sweep the system now." button to get a full list if auto-sweeping is not enabled.)
# Acknowledge the changes once you have updated the Eiffel system accordingly (possibly no change is required in the case of a simple edit in the external resource).
== Current limitations ==
The tracking of external resource changes is limited to external resources that are local files. If an external resource is a URL, it will not detect any potential changes done at that URL.
=== Affected items in the system caused by external resource change ===
# Open a class, add an Information entry with an external document (limited to local files in 7.3) in the class.
# Start working on that document, save it at as you normally do on regular basis.
# Open Info tool, go to Affected target in the left tree.
# Check the list of targets that might be affected by last changes of the document. (You may need to click on the "sweep the system now." button to get a full list if auto-sweeping is not enabled.)
# Acknowledge the changes if you find that current system does not need a change for last changes of the document.

* EiffelStudio will now show you contracts of a feature when completing code, letting you quickly find out the proper way to call it
* When debugging, moving the mouse pointer over an expression will cause the debugger to evaluate the expression and display its computation result in a tooltip.
===Improvements===
* Used void-safety settings of a target to list libraries that are compatible with it and provided more details on their void-safety status in the dialog for adding libraries.

* In [[AutoTest]], tests will be executed under the location of the Eiffel configuration file (ECF) and not in the Testing subdirectory of the EIFGENs directory.
===Bug fixes===
* Fixed a memory corruption that would occur when you have multiple errors during a compilation and you are opening each error in its own tab editor, after opening 4 or 5 tabs, EiffelStudio could become unstable.

* Updated <e>ROUTINE</e> and descendants to be usable for agents with separate targets.
* Fixed a comparison bug with <e>EQUALITY_TUPLE</e> which actually would only compare the last elements.
* Made <e>INTERNAL</e> obsolete, it is now replaced by two set of classes: a static introspection class and a dynamic one. The class that lets you examine the static content is <e>REFLECTOR</e>; most references of <e>INTERNAL</e> can easily be replaced by <e>REFLECTOR</e>. To inspect objects, you have a new set of classes starting with <e>REFLECTED_OBJECT</e>. This let you inspect objects with copy semantics without actually causing a copy each time you access it, unlike what was happening before with <e>INTERNAL<e/>.
