[[Property:link_title|18.11]]
[[Property:weight|-1]]

==Graphical environment==
* The debugger marks a class routine with a special icon in the call stack and prevents using non-class features in the watch tool inside a class routine.
* The completion popup dialog shows the associated target class (if any) at the top of the dialog.
* The class tool displays description of classes (if enabled).
* The diagram tool has improved drawing of figures and connectors.
* After refactoring, the editor restores current position as expected.
* A project can be recompiled from scratch from the ''Project'' menu.
* Editor tabs can be exported and imported via the hidden experimental menu ''Service > Import/Export tabs...'' ({{Key|Ctrl+Alt+D}}).

==Compiler==
* Assertion expressions are used as tags for assertions without explicit tags.
* Concurrency and void-safety project settings can be overridden when compiling from the command line.
* Project settings can use conditions based on void safety level.
* Checks for void safety of object initialization take into account an assigner command.
* Exception traces in final and workbench mode use the same breakpoint indexes.
* Several code-generation and run-time bugs are fixed.

==Libraries==
* All container classes are now <e>ITERABLE</e> that allows for iterating over them with the <e>across</e> loop and simplifies conversions between different types of containers. {{Inline-Warning|Potential incompatibility}} for descendant classes that did not implement <e>new_cursor</e>.
* <e>duplicate</e>, <e>duplicate_all</e> and related features of container classes are now obsolete to simplify inheritance from these classes in the future. The affected effective classes now have the feature <e>make_from_iterable</e>.
* Figures in Vision can be drawn with anti-aliasing (on Windows).
* <e>HASH_TABLE</e> now takes arguments of type <e>G</e> instead of <e>detachable G</e> and introduces a feature <e>definite_item</e> of type <e>G</e> (in addition to the existing feature <e>item</e> of type <e>detachable G</e>).
* OpenSSL binding uses <code lang="text">OpenSSL 1.1.1a</code> and supports new asymmetric algorithms (RSA).
* JWT (JSON Web Token) supports custom JWT algorithms. The associated extension library provides RSA signing algorithms.
* Performance of the JSON parser is improved by 40% on large regular files.
* The new function <e>JSON_VALUE.chained_item (a_key): JSON_VALUE</e> allows for expressions <e>json @ "person" @ "address" @ "city" </e> to get associated JSON value.
* ''ROC CMS'' implements protection against cross-site scripting attacks.
* ''EiffelWeb'' adopts nanoseconds timeout precision and supports suffixes <code lang="text">ns</code>, <code lang="text">us</code>, <code lang="text">ms</code>, <code lang="text">s</code> for the standalone connector in the initialization file.
* ''EiffelWeb'' correctly uses the setting <code lang="text">socket.timeout</code> for ''httpd'' (before the misuse of the setting caused high CPU usage for WebSocket).
* Creation procedures of some container classes are now secret. {{Inline-Warning|Potential incompatibility}} for clients of the classes.

==Tools==
* Code analyzer does not report false positives for the rules about an unread variable (<code lang="text">CA020</code>) and replacement of a regular loop with an iterative form (<code lang="text">CA024</code>).

==Examples==
* <e>processor_pool</e> demonstrates how a pool of active SCOOP processors can be used to execute tasks from passive regions.
