Hi all,

I've made some changes; let loose the grammar police!

http://freegis.org/cgi-bin/viewcvs.cgi/web/announces/announce_grass570.html


Three outstanding questions:

a) what to say regarding stability? I put the "technology preview" back
in, but commented it out as it isn't exactly right.. I thought "a first
release", while true, made the meaning a bit too obscure/hidden.

b) should the grass logo be included? It always looks nice.
related: Should there be a flat text version for a press release?
5.3.0 too..

c) I'm still not very happy with the first sentence.
