Debian: How to see what has recently been upgraded or updated through apt-get

Forgotten what it was you last updated, or want to check what someone else has been updating? There’s a log file for that, and it’s located at:  
/var/log/apt/history.log
  To view it, run:  
less /var/log/apt/history.log
  Looking for an older logfile? They’re kept, too. To see the other log files available, view the directory using ls:  
ls /var/log/apt/
  It should look something like:  
history.log  history.log.1.gz  history.log.2.gz  history.log.3.gz  history.log.4.gz  term.log  term.log.1.gz  term.log.2.gz  term.log.3.gz  term.log.4.gz
  One further note – This will show the most recent things done with apt, not just upgrades.
