Virtual Treeview update to version 4.7.0

Written by Mike Lischke
Sunday, 24 August 2008

I'm pleased to announce a new update of the popular Virtual Treeview control. Version 4.7.0 replaces the old 4.5.2 package. Thanks to Daniel Bauten and Jim Kueneman, as well as other helpers, Virtual Treeview is now ready for the latest Delphi version, including proper handling of the new Unicode strings.
It has been a long time since the last update but while I'm rather busy with other stuff others have taken care and sent me patches or got direkt write access to the main VT repository to directly commit their changes. Even if the Fisheye server (the web interface to my SVN repositories) is usually down (due to its system resource consumption) you can always get the latest source code and a nice development history by using one of the free SVN clients (e.g. TortoiseSVN for Windows, SmartSVN for Mac OSX/Linux) with the address svn://www.soft-gems.net/library.

Die Virtual Treeview history
wurde noch nicht aktualisiert.

Einen Changelog habe ich dann direkt in der Unit VirtualTrees.pas gefunden.

Stimmt das? Ich meine, es gab im SVN immer mal wieder Updates nach 4.5.2...

Danke für die Info, wobei die 4.7.0 bei mir schon länger läuft 8)

Im SVN schon jedoch ist V. 4.7.0 ein "offizielles" Update, welches nun direkt auf der Webseite zum Download bereit steht.

So gesehen, hast Du natürlich recht.
