• Fixed bug list: list of all bugs that have been fixed in 4D v19 R8.

Behavior changes

• For HTTP RFC compliance, HTTPRequestClass.response.headers property now returns all header names in lowercase. If you want your code to continue working as before, use the new HTTPRequestClass.response.rawHeaders property.
• When a bevel button with linked pop-up menu is assigned a standard action, the standard action is no longer generated if a pop-up menu option is selected.
• In Web areas using blink (CEF), dialogs displayed from external scripts are now blocking if not called from a setTimeout() JS function. This is due to the current CEF updates, in which dialogs displayed by functions such as alert() or print() are no longer handled by the OS but by the Web area. See WA Evaluate JavaScript and WA EXECUTE JAVASCRIPT.

Behavior changes

• For consistency with standard interfaces (e.g. OS file explorers), list box rules for row selection/drag and drop have been modified. A continuous or discontinuous selection of rows can be dragged by simply clicking on and moving a selected row; the Alt key is not longer necessary (but can still be used like in previous previous). When the Shift or Ctrl/Command key is pressed, a mouse click is taken into account when the click is down. For more information on drag and drop in list boxes, you can refer to this blog post and download this HDI 4D project.
• The 4D internal build numbering has been modified as of 4D v19 R7:
  • releases up to 4D v19 R6 (included) are numbered 282xxx,
  • releases from 4D v19 R7 will be numbered 100xxx.
    Note that a specific 4D version is still uniquely identified by a branch name and a build number. The build number increases chronologically.
• The ability to use Wakanda/4D Mobile REST protocol to call a project method has been removed. You can use ORDA data model class functions or /4DACTION urls instead.
