ecb这个提示是干啥？

There are no incompatible or renamed options. Your settings are correct.
But ECB must store that the ecb-settings are uptodate with 2.40.

Click on [Save] to save `ecb-options-version' (2.40) into /home/wang/.emacs.
This makes a backup of this file unique named with a suffix .before_ecb_2.40.

Click on [Close] to kill this buffer (do this also after clicking [Save]).

For a list of the most important NEWS call `ecb-display-news-for-upgrade'!

点了save下次开开还是有
