* tkperl5a5 is announced Thu, 20 Oct 1994 14:44:23 +0000 (BST)
NOTEThis project is unrelated to the one which is adding usersubs toperl4 to get access to Tk via Tcl. Often, postings on comp.lang.perljust say "tkperl" without saying which one is meant. They are twototally different kettles of fish.--Malcolm (Beattie)

26. 关于pTk和Perl/Tk的历史
（译者注：这一段是关于Perl/Tk的发展过程的情况，但是因为原著的创建时间实在是太老了，所以感觉原文的内容实在很“过时”了……就不译了——没什么意思——还是看看目前的Tk8的历史吧：）

Fix to build and run as much as possible on Solaris and Win32.
Menus and Fonts have changed radically in the core.
Tcl/Tk's menu.tcl has been hand converted (mostly) to Menu.pm and Menubutton.pm.
Menus mostly work - there will typo's in all that hand conversion.
No attempt has been made to make Font stuff visible to perl, indeed
existing Tk::Font is ideal candiate API (very close to what Tcl has), but probably
does not work at the moment.
Other big snag is fileevent is now completely broken on all platforms.
I need to re-implement enough of Tcl_Channel API on top of perl's file handles
to re-introduce it. This will be main focus of Tk800.001 ...
实在太长了，就懒得译了，有兴趣自己看看吧！J
目前在Tk800分支中最高版本好像应该是2003年9月8日发布的Tk800.025。另外还有一个Tk804的分支，前些日子（2003年12月14日）刚发布了Tk-804.025_beta10，其说明如下：
Changes in Tk804.023
First public release of version based on Unicode aware core tk.
老实说，我本来平时并不是太关心这些的……所以如果有什么不尽之处，还请大家谅解。
