= EiffelStudio 7.0.x Releases=

==7.0.x==
Placeholder for new stuff since last intermediate release.
===New features===
===Improvements===
* compiler: Avoided reporting errors related to variable initialization when the right-hand part of assignment to this variable causes an error.

===Feature removed===
===Bug fixes===
* compiler: bug#16974 (test#term187) - Fixed a bug that caused a compiler crash on a particular kind of formal generic constraints.
* compiler: bug#17057 (test#term190) - Fixed processing of invalid formal generic constraints that could potentially lead to a crash.

==7.0.8.7345 (September 28th 2011)==
===New features===
* compiler: Supported development of incomplete void-safe classes (so called "design mode") by avoiding reporting void-safety errors for unreachable code, e.g. for the code after a call to a feature that never returns normally, say, to <e>{EXCEPTIONS}.die</e>. So a creation procedure that does not initialize attached attributes properly (because the corresponding effective classes are not available yet), can look like
<e>
make (...)
	do
		... -- Some attributes are not initialized.
		die (1) -- Compiler does not report VEVI errors.
	end
</e>
:or
<e>
make (...)
	do
		... -- Some attributes are not initialized.
		check implemented: False then end -- Compiler does not report VEVI errors.
	end
</e>

===Improvements===
* compiler: Enforced full class checking for void-safe classes.
* compiler: Supported detection and report for the configuration error <code>VD88</code> of void-safety mismatch when a descendant or a client have stricter void-safety setting than the corresponding ancestor or supplier.
* compiler: Taken into account changes of class options when performing recompilation.
* compiler: Added a new validity error <code>VBAC(3)</code> for assigner calls when the target is a stable query.
* compiler: Supported an option "stable" for any feature, not only for an attribute.
* compiler: Changed conditions under which <code>VFAC(3)</code> is reported to follow the recent modifications to the standard.
* compiler: Supported detection and report of an error when a recently approved assignment validity rule <code>VBAR(2)</code> is violated.

===Feature removed===
===Bug fixes===
* compiler: bug#11675, bug#15010 - Included location information in VTCT error and VTCM warning reports.
* compiler: bug#15178 (test#incr303) - Fixed bug that caused incorrect VTEC(2) report during incremental recompilation.
* compiler: bug#16942 (test#anchor046), bug#17815 (test#anchor062) - Fixed a crash caused by a combination of a qualified anchored type and its dependency on a formal generic constraint.
* compiler: bug#17731 (test#scoop013) - Fixed error in C code generation for separate feature calls when inlining is enabled.
* compiler: bug#17736 (test#vffd802) - Avoided reporting VFFD(8) for process-relative once procedures.
* compiler: bug#17740 (test#scoop016) - Fixed error in C code generation for separate calls to attributes with zero offset.
* compiler: bug#17743 (test#scoop017) - Provided code generation for separate feature calls to constant attributes.
* compiler: bug#17748 (test#scoop018) - Fixed errors in code generation and run-time for manipulating possibly boxed values that might cause an executable to crash.
* compiler: bug#17764 (test#attach087) - Considered <e>like Current</e> as attached regardless of <code>is_attached_by_default</code> option.
* compiler: bug#17765 (test#attach089) - Prohibited assignment of <e>Void</e> to a variable of a reference formal generic type that has no <e>detachable</e> mark.
* compiler: bug#17766 (test#attach088) - Supported attachment marks on the type <e>NONE</e>, including implicit setting via attached-by-default option.
* compiler: bug#17778 (test#attach062) - Corrected checks for attachment status of variables to include not only a body of a loop, but also its invariant, variant and exit condition when a variable may be detached in the loop body.
* compiler: bug#17779 (test#attach091) - Corrected conditions for which <code>VFAC(3)</code> is reported to follow the forthcoming modifications to the standard. Supported detection and report of an error when <code>VBAC(3)</code> introduced in the forthcoming version is violated.
* compiler: bug#17806 (test#attach090) - Taken into account attachment status of <e>like Current</e> when checking for conformance.
* compiler: test#attach092 - Corrected processing of self-initializing attributes to follow the standard rules.
* compiler: test#attach093 - Ensured the bodies of self-initialized attributes are not considered as setting other attributes because their evaluation is optional and depends on whether the attributes were accessed before or not.
* compiler: test#scoop020 - Taken separateness status into account when checking for formal generic type equality and conformance as well as when substituting actual generics.
* base: bug#17806 - Made <e>{LINKED_STACK}.duplicate</e> void-safe.
* time: test#term195, test#eiffelstore001 - Made a postcondition in <e>{INTERVAL}.intersection</e> void-safe.
* vision2: bug#17806 - Made <e>{EV_TABLE}.duplicate</e> and <e>{EV_DYNAMIC_LIST}.new_chain</e> void-safe.
* vision2: bug#17824 - Avoided VUTA(2) validity rule violation in <e>{EV_GRID_ROW_I}.update_parent_expanded_node_counts_recursively</e>.
* base: Fixed issue with various routines of READABLE_STRING_xx which would not generate the correct result when used on IMMUTABLE_STRING_xx created via `shared_substring' with a lower index other than 1.

===User changes===
* argument_parser: Made feature <e>{ARGUMENT_BASE_PARSER}.copyright</e> deferred.
* vision2: Relaxed precondition on `set_focus' to let you set the focus even if the widget is not displayed. Note that in this case the `set_focus' call will have no effect. This is necessary because testing Vision2 code in a window less environment could violate the precondition and it would be rather expensive to change all callers of `set_focus' to check this all the time.
