In the newest release of R (R 3.0.0), the "glm" package

Was this intentional?  What package is best to use in the 
newest version of R to perform logistic or probit regression?

 I would be very skeptical about that claim. 
Where is your evidence? Have you looked at:

?family  # ?
?quasi   # ?

I'm skeptical too. 'glm()' is the 'stats' package which comes
with R and is automatically loaded.

  glm(...,family=binomial)  runs a logistic regression

(the default link is logit, so this is equivalent to 
family=binomial(link="logit"), if you prefer explicitness
over brevity)

  glm(...,family=binomial(link="probit"))

runs a probit regression.

   I'd actually be quite curious to hear how you reached
this conclusion, in case there is confusing or mis-information
going around that we can correct ...
