  Very recent measurements of stellar winds are used to update relations
between winds and coronal activity. New wind constraints include an upper limit
of Mdot<0.1 Mdot_sun for Tau Ceti (G8 V), derived from a nondetection of
astrospheric H I Lyman-alpha absorption. This upper limit is reported here for
the first time, and represents the weakest wind constrained using the
astrospheric absorption technique. A high mass loss rate measurement of Mdot=10
Mdot_sun for Delta Pav (G8 IV) from astrospheric Lyman-alpha absorption
suggests stronger winds for subgiants than for main sequence stars of
equivalent activity. A very low mass-loss rate of Mdot~0.06 Mdot_sun recently
estimated for GJ 436 (M3 V) from Lyman-alpha absorption from an evaporating
exoplanetary atmosphere implies inactive M dwarfs may have weak winds compared
with GK dwarfs of similar activity.
