From the site release notes at
LauncherPro
Warning: This update is mainly targeted at people having memory-related force-close issues, so if you’re not having any of those you’ll find this update pretty uninteresting (I did include something for you though!).
Ok, so the new Memory Usage option was very well received and seems to have solved a lot of issues for many, so I’ve decided to take it a step further. I’ve added an entire category in the preferences dedicated to memory management. Here you can tweak all the memory usage options for LauncherPro and make your own profile.
The old Memory Usage settings are now presets of these new settings. The “Light” option is now the “Moderate” preset, and there’s three new presets: Light, Low, and
Very Low. Try them out and find the configuration that works best for your setup.
There’s also newer memory usage options that weren’t available before, namely the type of caches to use for homescreens, and the option to disable caches altogether.
The normal cache type is the one LauncherPro has always used. The compressed type will save quite a bit of memory but might affect scrolling speed (on certain phones only, make sure to give it a try). The light type will save even more memory and might even run better than the compressed type on some phones. There’s no one-size-fits-all setup on Android, different phones have different hardware and different builds of the operating system. Please give these new options a try and see what works best for YOU.
Here’s a short log of what’s new in 0.6.4:
Fixed some force-close issues when removing packages from the Market in Froyo
Improved some code which should make screen rotations a little bit faster. Please note that android KILLS the homescreens when rotating, so all widgets, icons, etc. have to be redrawn. That’s just how Android works.
New “Memory Usage Settings” screen on the preferences.
New option to disable homescreen caches.
New option for normal, compressed, and light homescreen caches.
New option: outline highlights. These are like the glow highlights only they are a solid outline around the icon, so they are more visible than the glow highlights. You can choose between Classic, Glow, and Outline highlights under Appearance Settings on the preferences.
That’s it for now. Next version should include some fixes for Froyo (thanks Google for once again releasing the source code too late so us developers now have to scramble to fix whatever the new version breaks in our apps). After that, it’s back to adding more features and more eye candy
