Hi,

Gambas 3.21.0 is now officially released.

Among the hundreds of fixes and enhancements, the main features of this 
release are the following:

In the development environment:

- A new GUI theme with configurable roundness, flatness and contrast.
- A better debugging of web applications.
- The image editor has better selection and grid drawing, and faster 
vector shapes loading.
- A new process manager that displays all Gambas interpreter currently 
running on the system.
- The debugger panel can be undocked, and put on another screen if needed.
- The project tree filter has been fixed.
- Version control now allows to commit files individually.
- Version control allows to cherry-pick commits.
- The IDE is now colorized according to the current branch.

In the core language:

- The '[/lang/clamp]' function, that clamps a value between a minimum 
and a maximum.
- A new '[AFTER DO](/lang/after)' syntax that executes a statement later.
- A new '[EVERY DO](/lang/after)' syntax that executes a statement 
repeatedly.
- The '[/lang/fromhtml]' function, that removes all markups and entities 
of an HTML string.
- The '[/lang/tokenize]' function, that splits a string into tokens and 
returns them.
- The '[/lang/ninstr]' function and the 
'[String.NInStr](/comp/gb/string/ninstr)' method, that return the number 
of occurrences of a substring inside a string.
- The '[Process.Exist](/comp/gb/process/exist])' method, that checks 
whether a process having a specific identifier is running.
-  Subroutines optional arguments can be skipped, like other function calls.

Otherwise:

- Support for recent versions of 'gcc'.
- Many fixes in the 'gb.db2' components.
- The '[Paint.Shear](/comp/gb.qt4/paint/shear)' method, that allows to 
shear the paint transformation matrix.
- The '[Font.Spacing](/comp/gb.qt4/font/spacing)' property, that allows 
to define the horizontal space between characters.
- The 'gb.httpd' component is now a true embedded HTTP server.
- The 'gb.web.gui' component has now [painting 
capabilities](/comp/gb.web.gui/paint) similar to the GUI components.
