How to upgrade from earlier versions of GnuPG?
----------------------------------------------

  You should be able to just copy !GnuPG from the archive you downloaded over
your old copy of !GnuPG on your hard disc.

  Concerning !GnuPGUser you should take more care: There are  options defined
in !GnuPGUser.!Boot and in !GnuPGUser.gpg/conf (formerly !GnuPGUser.options).
You should always look what has  changed and add options you want by  hand to
your original configuration file, otherwise you may lose your old options. Or
even better, take the new configuration  file and make the same modifications
you did to the old.



Upgrading from 1.0.7 to 1.1.92 or later
---------------------------------------

  There has been a name change of  the options file in order to prepare  name
consistency for future changes. The new file is called  'gpg/conf' instead of
'options'. If only the old one is available, nothing special happens. If only
the new  one is available,  nothing special happens  as well  (obviously). If
both versions (i.e. 'options' and 'gpg/conf') are available, then the new one
will be used and a warning about the old one will be printed.


Upgrading from 1.0.6 to 1.0.7
-----------------------------

  In order to get best performance with larger keyrings, it is suggested that
you run the new command  "gpg --rebuild-keydb-caches" once. We tried  to make
the migration to 1.0.7 as smooth as possible, but it might be  a good idea to
backup  your  keyrings and  the  trustdb  ("gpg --export-ownertrust")  first.
Please note however that due to a bug in prior versions, it won't be possible
to  downgrade   those  keyrings  to   1.0.6.  After  having   done  the  "gpg
--rebuild-keydb-cache",  it is advisable to  perform an "gpg --check-trustdb"
as well.

  Further, ultimate trust is no longer assigned automatically when there is a
secret key in the secret keyring. Users must now set the  ownertrust of their
own keys to ultimate trust. This can be done by means of the "gpg --edit-key"
command. If no  ultimate trust is  set, the web of  trust will not  work, and
GnuPG will report that the ownership of a key  has not been validated even if
you  have signed  that key  with  your own  key.  Therefore you  have to  add
ultimate trust to your own  keys by doing "gpg --edit-key <mykeyid>" for each
of your own keys.



  Additionally, you  should have  a look  at the  !GnuPG.!Help  file. It  may
contain further instructions, e.g. information for new features, etc.
