I just realised that Offline in Gmail Labs is currently in its 0.4 version. Anyone noticed any difference?

[changed 4.0 to 0.4 ~ hebbet]

Correction: It says 0.4 on mine.

Official Gmail Blog says:

<< Send attachments while offline

One of the most requested features for Offline Gmail has been the ability to include attachments in messages composed while offline. Starting today, attachments work just the way you would expect them to whether you are online or offline (with the exception that when you're offline you won't be able to include inline images). Just add the attachment and send your message. >>

i have changed the number because it could be confussing.
if you have 4.0, Keith, let us know via a screenshot

Ooops .. it's a typo, sorry! It should be 0.4. Thanks, hebbet.
