Abort: unsynchronized remote changes?

Question

I got a warning like this

abort: unsynced remote changes! 

How can I 1) See what is the difference? hg diff? hg status? 2) Code negotiation?

Thanks in advance. This is what I got while working hg, checking the heads.

Answer 1

You must pull the latest changes before clicking:

 hg pull 

To view the differences before clicking:

 hg in 

After pulling, you need to combine the changes that you pulled with the changes that you are trying to click:

 hg merge 

After the merge, you will need to perform the merge:

 hg commit 

Finally, click without errors:

 hg push 

Answer 2

Just follow

 hg incoming 

You will see a list of changes available on the remote side.
