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
simulations
* 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
