Hi,

I have at least extracted all the projections which require updating
from +proj=stere to +proj=sterea in QGIS 0.8.

In Proj 4.5 beta and Gdal 1.3.2 sterea is used in GDAL for 14 European
stereographic grids (18 listed below, but 4 are duplicate "deprecated"):

$ grep -B1 '+proj=sterea' /usr/local/share/proj/epsg | awk '/^#/ {print}
/^</ {print $1" "$2}'

# NAD83(CSRS98) / New Brunswick Stereo (deprecated)
<2036> +proj=sterea
# Pulkovo 1942(58) / Poland zone I (deprecated)
<2171> +proj=sterea
# Pulkovo 1942(58) / Poland zone II
<2172> +proj=sterea
# Pulkovo 1942(58) / Poland zone III
<2173> +proj=sterea
# Pulkovo 1942(58) / Poland zone IV
<2174> +proj=sterea
# ATS77 / New Brunswick Stereographic (ATS77)
<2200> +proj=sterea
# ATS77 / Prince Edward Isl. Stereographic (ATS77)
<2290> +proj=sterea
# NAD83(CSRS98) / Prince Edward Isl. Stereographic (NAD83) (deprecated)
<2291> +proj=sterea
# NAD83(CSRS98) / Prince Edward Isl. Stereographic (NAD83) (deprecated)
<2292> +proj=sterea
# NAD83(CSRS) / New Brunswick Stereo
<2953> +proj=sterea
# NAD83(CSRS) / Prince Edward Isl. Stereographic (NAD83)
<2954> +proj=sterea
# Pulkovo 1942(58) / Poland zone I
<3120> +proj=sterea
# Pulkovo 1942(58) / GUGiK-80
<3328> +proj=sterea
# Deir ez Zor / Levant Stereographic
<22780> +proj=sterea
# Amersfoort / RD Old
<28991> +proj=sterea
# Amersfoort / RD New
<28992> +proj=sterea
# Dealul Piscului 1933/ Stereo 33
<31600> +proj=sterea
# Dealul Piscului 1970/ Stereo 70
<31700> +proj=sterea


It is necessary to update this in QGIS before 0.8 release to spare users
problems and possible data corruption.

Sorry I can't do it myself. I hope this tip helps though.
