Changes are listed below.

NOTE: The next release of rms will replace the survfit.formula function 
with a new function named npsurv ("nonparametric survival estimates") so 
as to not conflict with the survival package.  This is a 
NON-DOWNWARD-COMPATIBLE change.  To get Kaplan-Meier estimates in the 
NEXT release use npsurv() instead of survfit().

Changes in version 4.1-3 (2014-03-02)
    * num.intercepts: removed (is in Hmisc)
	 * survfit.formula, cph, psm: changed to use inputAttributes attribute 
of Surv objects (introduced earlier in survival package so that rms 
could drop its customized Surv function)
    * Exported survfit.formula
    * Changed survival fitting functions and residuals to use units.Surv

Changes in version 4.1-2 (2014-02-28)
    * psm: Fixed bug to allow computation of Dxy with left censoring
    * val.prob: Fixed recently introduced bug that made calibration 
intercept and slope always 0,1.  Thanks: Lars.Engerstrom at lio.se
    * plot.Predict: added between to leave space between panels
    * orm.fit: fixed error in kmid calculation when heavy ties at first 
level of y.  Thanks: Yuwei Zhu
    * setPb: changed default to now use tktcl to show progress bars for 
    * predictrms: fixed bug with type='terms'
    * val.surv: handle case where survival estimates=0 or 1 when using 
log-log transform

Changes in version 4.1-1 (2014-01-22)
    * Removed use of under.unix in anova.rms, latex.summary, plot.nomogram
    * Removed use of oldUnclass, oldClass, is.category
    * Fixed class of Rq object; had failed with bootcov.  Thanks: Max Gordon
    * survplot: preserved par()
    * Srv: removed, changed all uses to Surv() for new survival package 
that preserves attributes for Surv inputs
    * survplot.survfit, survdiffplot: added conf='diffbands'
    * predictrms: fixed num. intercepts calculation order
    * survplot, survdiffplot: used original standard error for 
survdiffplot, and fun
    * dyx.cens: allow left-censoring
