とPEARの中の人が仰せです。
Joining the GoPHP5.org's movement
After being the leader and most used PHP applications and libraries for many years with over 30 Million downloads, the PEAR Project is happy to announce that the next version of PEAR, named PEAR2, is going to aim at being only available for PHP5.2 and newer versions of PHP.
PEAR2 is currently not released but under development with a new installer (Pyrus) coming along the way. Using the benefits of the PHP Archiver (PHAR) and the features that PHP5.2 offers, we can now produce better applications than ever using the PHP language.
Thanks to all our users and especially our dedicated developers for making this possible. Without them, we would not be able to achieve and reach a goal that has been important to us for the few past years, moving to PHP5.
まあしかし、実際のところはレンタルサーバ業界がどう動くかによって、移行の時期というのは変ってくると思うな。自分で鯖立ててる会社もそれ程多くはないでしょ。
大手のレンタルサーバ屋の動向を注意して探っていきたいと思います。ロリポップとXREAかな。とりあえずは。
