updates

[Me - Atlantic]

I have a production server running Breezy (5.10).  Checking updates this
morning, I have this as upgrade-able packages:

Inst php5-cli [5.0.5-2ubuntu1.2] (5.0.5-2ubuntu1.3
Ubuntu:5.10/breezy-security) []
Inst php5-cgi [5.0.5-2ubuntu1.2] (5.0.5-2ubuntu1.3
Ubuntu:5.10/breezy-security) []
Inst php5-mysql [5.0.5-2ubuntu1.2] (5.0.5-2ubuntu1.3
Ubuntu:5.10/breezy-security) []
Inst libapache2-mod-php5 [5.0.5-2ubuntu1.2] (5.0.5-2ubuntu1.3
Ubuntu:5.10/breezy-security) []
Inst php5-common [5.0.5-2ubuntu1.2] (5.0.5-2ubuntu1.3
Ubuntu:5.10/breezy-security)
Inst linux-image-2.6.12-10-386 [2.6.12-10.35] (2.6.12-10.36
Ubuntu:5.10/breezy-security)
Inst php5 [5.0.5-2ubuntu1.2] (5.0.5-2ubuntu1.3
Ubuntu:5.10/breezy-security)
Conf php5-common (5.0.5-2ubuntu1.3 Ubuntu:5.10/breezy-security)
Conf php5-cli (5.0.5-2ubuntu1.3 Ubuntu:5.10/breezy-security)
Conf php5-cgi (5.0.5-2ubuntu1.3 Ubuntu:5.10/breezy-security)
Conf libapache2-mod-php5 (5.0.5-2ubuntu1.3 Ubuntu:5.10/breezy-security)
Conf php5-mysql (5.0.5-2ubuntu1.3 Ubuntu:5.10/breezy-security)
Conf linux-image-2.6.12-10-386 (2.6.12-10.36
Ubuntu:5.10/breezy-security)
Conf php5 (5.0.5-2ubuntu1.3 Ubuntu:5.10/breezy-security)

Is there a way to find out what changes are made to cause these
upgrades?  Everything on the server appears to be running ok, so I don't
want to make changes to services like apache and php without more
information about what 'needs' to be changed.
