More observations:

1) Map
- Supposedly there's minor update but it's probably really minor I don't see.
2) hildon-desktop & modest:
- Latest git version as expected.
- Live search now shows the word you typed immediately even if you are in a folder with large number of files.
3) Microb (20100401-1.9.2-5.2+0m5/2.9.5-1.23+0m5):
- No "open link in background" option.
- In fullscreen mode, reflow keyboard shortcut still turn into auto focus on address instead.
4) PulseAudio (0.9.15-1maemo43+0m5)
- Seems to have less stuttering under heavy loading, or it could be HAM takes less load now.
5) Camera:
- No visible change in options.
- Auto focus speed seems to be a tad quicker.
- When front camera is used, say by Mirror, the indicator light turns red.
- Video still has frame-drop issue in highest quality setting.
5) QT4.7: Some QT packages will need updating to work properly.
6) Dual boot: Errr... I don't know how to test this.
