I'm happy to release B4i v4.81. This update includes the IDE improvements recently added to B4J and B4A.

Several important components were rewritten to provide more features and better performance:
  • Visual designer properties grid
  • Visual designer views tree
  • Modules tree (new component)
  • Files tree
The major improvements are:
  • Code modules can be loaded from other folders and can be easily shared between projects (including projects targeting other platforms): https://www.b4x.com/android/forum/threads/b4x-modules-files-groups-and-folders.86587/


  • Modules and file tree support grouping:


  • Modules are monitored for external changes.
  • Files tree shows the files icons and allows opening the files with external editors: https://www.b4x.com/android/forum/threads/b4x-external-editors.86592/


  • Modules, files and views can be renamed directly from the relevant tree.
  • Full support for drag and dropping files and modules, including support for dragging multiple items.
  • B4A services and activities can be shared with B4J and B4i: https://www.b4x.com/android/forum/threads/b4x-sharing-modules-and-classes.87478/
  • New options when adding modules:


    Copy to folder: Copies the module to the project folder (same as the current behavior).
    Link - relative path: Adds a link to the module with a relative path. Useful when the folder is under or close to the project folder.
    Link - absolute path: Adds a link to the module with an absolute path.

  • Deleted files are moved to the recycle bin.
  • Properties grid and views tree can be filtered.
  • Properties grid is much faster and includes new types of editors:


  • The modules internal attributes are sorted in lexicographical order to reduce random changes.
  • iXUI library is now an internal library.
  • Debugger hover window is resizable.
  • Add New Modules / Existing modules menu items in modules tree.
  • Code editor color picker is based on the designer color picker.
  • Open file with default program in Files tree. Also works with double click.
  • Support for opening multiple files at once.
  • Builder - better handling of certificates changes.
  • Compiler error for incorrect calls to resumable subs.
  • Hosted builder - prefer secondary builder option. Useful if a builder partially fails.
  • Page.SafeAreaInsets - Returns the distances from the four edges that are considered safe. This is relevant for devices such as iPhone X where parts of the screen are hidden.
  • NativeObject new methods: MakeEdgeInsets, ArrayFromEdgeInsets, ArrayFromPoint, ArrayFromRect, ArrayFromSize, ArrayFromRange
  • Bug fixes and other minor improvements.

Developers who are eligible for a free upgrade will receive an email with upgrade instructions.

V4.81 is available for download from the same link. It fixes an issue with library compilation.

Hi, a quick question (didn't receive the email though I have an active license for B4i) => the "same download link" would be which? The one for v 4.80? Thanks for a hint!
Edit --- OK just tried the 4.80 link and it's the most actual one for 4.81 :)
