  • GNATCOLL.Atomic: Sync_*_Compare_And_Swap_Counter
    New atomic operations are provided, that change the value of an Atomic_Counter if, and only if, it currently has a given known value. This is useful to write lock-free algorithms.

    unicode names from the Unicode 8 standard
    The unicode-names-* packages were updated to match the Unicode 8 standard. The new bindings are generated via a new importer, which fixes a number of issues with the previous bindings:

       - some characters were put in the wrong block (and thus wrong package)
       - some typos due to incorrect parsing of the Unicode files
       - some name aliases would hide canonical names occurring later (for
         instance 1F5E2 was hidden by 1F48B)
       - some unofficial aliases were used (Bell is not long valid, for
         instance)
    
    This change is not fully backward compatible, due to changes in the Unicode standard itself, since some blocks were renamed, as well as some characters. Contributed by Nicolas Boulenguez

    Improved version of attribute Type_Key
    The attribute Type_Key, which is provided for compatibility with the APEX attribute of that name, now uses a CRC computed from the type declaration of the type, and the declaration of all its components, to provide a reliable signature that allows the detection of changes in the semantics of the type.

    GPS: tooltips show dirs relative to root project
    The tooltips in notebook tabs, in the Project view and in the Windows view now show both the absolute name for files as well as their location relative to the root project. The latter path can often be much shorter, depending on your setup.

    Setting the default verbosity
    It is now possible to control the default verbosity without to use switches -v or -q, with environment variable GPR_VERBOSITY. The possible values, case-insensitive, are "quiet", "default", "verbose", "verbose_high", "verbose_medium" and "verbose_low". Any other value is ignored.

    Runtime () as a relative path
    It is now possible to specify a runtime directory with the attribute Runtime as a relative path, in the main project. Example:

       for Runtime ("Ada") use "./rts";
    
    The path is relative to the project directory of the main project.

    gnatpp: alignment of exception declarations
    By default, gnatpp will treat exception declarations and exception renaming declarations similarly to object declarations and others, by aligning the ":" characters when multiple declarations appear one after the other with no intervening blank lines.

    GPS: Integration with QGen
    GPS now provides a convenient interface to QGen, the code generator for Simulink models. This includes: displaying graphically the diagrams from MDL files (read-only), toolbar buttons to easily generate code then build (and optionally then debug), tight integration with the debugger so that whenever the debugger stops, GPS highlights the current block in the diagram, adds contextual menus to easily break on specific blocks, and shows the current value of signals.

    Support for hashing arbitrary complex structures
    The family of secure hash packages based on GNAT.Secure_Hashes (including MD5, SHA1, and the various SHA2 functions) now provide a wrapper for hashing contexts that implements the Ada stream interface. As a result, stream attributes can be used to feed arbitrary complex data structures into hashing functions.

    GPS: view the tasks directly from the toolbar
    In the main toolbar, the button next to the summary of running tasks now brings up an ephemeral window which contains a task manager view, which allows viewing and interrupting tasks directly from the toolbar, without the need to have the Task Manager view present in the MDI.

    Add support for ‘Image and ‘Value to Cert runtimes
    Cert runtimes now support the same attributes and packages as Ravenscar Cert, except that Ada.Calendar and Calendar are not in the latter. New packages include various string-handling packages, less-restrictive Interfaces.C, etc. The main difference now between the two profiles is use of Ravenscar tasking vs. APEX processes.

    Warning on fixed-point actual with user-defined op
    Compiler emits a warning on the actual for a formal fixed-point type when the actual has a user-defined arithmetic operator but the generic unit does not include a formal subprogram for the operator. The warning indicates that the predefined operation will be used in the instance.

    Improving handling of User_Data
    The following generic packages were modified:

      Gdk.Event.Handler_Set_User_Data
      Gtk.Action_Group.Set_Translate_Func_User_Data
      Gtk.File_Filter.Add_Custom_User_Data
      Gtk.Widget.Add_Tick_Callback_User_Data
    
    
    The Notify parameter was removed from the public API. Instead, GtkAda will call the Destroy procedure to release User_Data.

    GPS: automatic fix for adding Elaborate_All pragma
    The GPS code fixing capability was enhanced to handle compiler messages such as "Elaborate_All pragma required for NAME". To fix this GPS will add pragma Elaborate_All (NAME) after corresponding with-clause in the spec or body of given compilation unit.

    Temporary config project with autoconfiguration
    The Project Manager now creates a temporary configuration project file when in auto-configuration. This file is deleted when the tool terminates. This allows several project-aware tools invocations to work in parallel with the same object directory.

    Tighter array packing for small record component
    The packing of array types subject to aspect/pragma Pack and whose component type is a small record, either that contains another small record component, or that has a size in the range 33 .. 63 bits, has been improved.

    GPS: Add the possibility to filter switches
    Switches defined for a specific tool using XML can now be filtered by specifying a named filter for the 'filter' attribute of a switch tag. These filters can be either predefined in GPS or created by the user (see the <filter> tag in the XML files). Use the GPS.Filter.list static method to list all the registered named filters.

    GPS: do not highlight occurrences of keywords
    The plug-in auto_highlight_occurrences.py highlights all occurrences of the word under the cursor in the whole file (possibly using smart cross reference information to only highlight the specific entity and not its homonyms). This plug-in has now learned not to highlight the language's keywords ("constant", "begin",...) which is useless and might be slow since these keywords generally occur often.

    GPS: Home goes to beginning or first-non-blank
    When using the Home key while in an editor (or any key bound to the action "beginning of line"), GPS will first go to the first column (as it has always done), but if you do it a second time it will then go to the first non-blank character of the line). This is a feature available in other code editors.

    GPS: width of omnisearch popup
    The width of the popup window for the omnisearch (at the top-right corner of the main window) is now proportional to that of the search field itself. And the width of the latter can be set by changing the settings, which is useful if you have long file names in your application.

    GPS: revamp the debugger Breakpoints view
    This view shows the current list of breakpoints set in the debugger. Its layout has been modified so that it is now smaller and can more easily be a permanent fixture of the desktop. Clicking on a breakpoint will display all its properties (both basic like file and line, exception name,... and advanced like the condition to be met for the debugger to stop).
