Two software search engines let you find "new love" and "old love"

Upgrade, upgrade, upgrade, software, like people, is constantly growing and changing. Often pay attention to the official website basically can get the latest version, sometimes also may not be, maybe the site administrator lazy, not for a long time to update the download entrance is not necessarily. In contrast, older versions are not so easy to get and are hard to find. This can be bitter software users, after all, users are emotional people, on the one hand, we have curiosity and desire for new things, on the other hand, we will try new things in the process or result of strong nostalgia, in the face of software, there will also be such emotional factors frequently produced. Friends who read this blog will not be sad, I will recommend two software search engines to everyone, so that friends can "new love" and "old love" both.
