==Migration from 1.6==

The several typical changes you should do for adopting your subsystems for 1.7 are listed bellow:

==== IN to VAR ====

Now it is forbidden to use a variable declared as IN parameter as the receiver of a method call that expects a VAR parameter. You should change the IN parameter to VAR or the VAR receiver to IN in such a case.

==== Read-only variables ====

With 1.7 you can not call the methods of a read-only variable object if there is VAR option in argument of method. So you should export such a variable by *.

==== WinNet ====

WinNet.hostnet definition [http://redmine.blackboxframework.org/projects/blackbox/repository/diff?utf8=%E2%9C%93&rev=b3f0ad9f9012f89fb110909485ef22d35a49a46e&rev_to=bc96c56d1c94894f8e2afaf4a919ad8e79cdae64 was changed], so you need to replace:

<code>inaddr := hostentry.h_addr_list^[0]^[0]</code>

to

<code>inaddr := SYSTEM.VAL(WinNet.in_addr, hostentry.h_addr_list^[0]^)</code>

==== Underlined white space ====

Underlined spaces and tabs are now shown according to the defined format, i.e. they are underlined. So we recommend you to check your documentation files and/or program generated text files to prevent unexpected underlines.

==== UTF8 ====

UTF-8 conversion supported "out of the box" from module <code>Strings</code>. So if you are using UTF-8 conversions embedded in your own code or from some third-party modules, you can switch to the new Strings procedures.

==== External calls ====

1.7 supports calling URLs (e.g. web pages, E-mails), so now you can be sure that the user can call your link from documentation even if external CPC subsystems such as Info or i21Sys are not installed.

Use the <code>Dialog.OpenExternal</code> procedure to call a URL.

==== Config & Converters ====

The new Converter.next* export allows uninstalling and ordering converters "on the fly" from any module
not just from the Config module used at BlackBox startup.

==Useful tools for migration==

There is the tool for batch compilation of subsystems: [http://forum.blackboxframework.org/download/file.php?id=124 ypkDevTool].
