Dear list members,

We are pleased to announce the release of LiveCode 9.0.0 DP-10.

Developer Preview Release
Warning: this is not a stable release.  Please ensure that you back up your
stacks before testing them.

Getting the Release
You can get the release at https://downloads.livecode.com/livecode/ or via
the automatic updater.

Release Contents
LiveCode 9.0.0 DP-10 comes with 27 bugfixes. Moreover, more than 40
bugfixes that were fixed in LiveCode 8.1.x and 8.2.x, are now merged into
LiveCode 9.0.0 DP-10.

In addition, LiveCode 9.0.0 DP-10 includes several amazing new features:

- Java-FFI: Added support for custom classes (.jar files) in desktop and
android apps
- Java-FFI: Use extensions' code folders to update jarfiles standalone
- LCB-Engine: Enabled getting the caller from LCB
- LCB-Language: Implemented send { command | function } <msg> and post
<msg> LCB syntax for libraries
- Implemented Native Scrollers for Datagrid object
- Implemented a HTML5 deploy library

Known issues
- The Browser widget can cause hang in the IDE in some Linux distros - see

- The Android Native Button widget uses "labelColor", not
"foregound"/"textColor" to set the text color

- You might not be able to run HTML5 standalones locally using the most
recent version of Safari or Chrome (Firefox is OK). This is due to those
browsers now prohibiting cross-origin-requests. To test out standalones
locally using these browser, we suggest using a local HTTP server as
described in the HTML5 deployment guide. However, this will not be a
problem if you use the new HTML5 deployment library, which does this for
you: You just have to choose one of the installed browsers (click on the
"Development -> Test Target" menu item), and then click on the "Test"

- [Business Only] If you use the new feature of HTML5 deployment from the
"Test" button, make sure you have unchecked "Script Debug Mode". See bug

The full release notes are available from:


Note: Due to the changes in LCB <post> and <send>, if your custom widgets
use these commands, you have to rebuild them in LC 9 DP-10 using the
Extensions Builder.

Have fun!
