* Data security: Symmetric/Assymetric encrytion algorithms (aesutil
and gpg encryption), Encryption can be done on server or client,
Custom encryption utilities can be used.
* Compression: Ability to add custom compression tools. This is a
really useful feature especially since it can specified for a DLE. You
can use different compression algorithm for images, binaries, ascii files
and so on.
* Dump images spanning multiple media volumes - Dump images are no
longer restricted to a single media volume (tape or vtape). Data restoration
can be done using amrecover and amfetchdump commands.

k=kilo, m=mega, g=giga, t=tera.

and large disk.
* bumpsize, bumppercent, bumpdays and bumpmult can be in a dumptype.
* calcsize support include and exclude like gnutar.
* new 'estimate' dumptype option to select estimate type:
CLIENT: estimate by the dumping program.
CALCSIZE: estimate by the calcsize program, a lot faster but less acurate.
SERVER: estimate based on statistic from previous run, take second but
can be wrong on the estimate size.
packages. Set runtime dependencies on GNU tar and gzip for all amanda
packages.
Bump PKGREVISIONs to 1 for amanda-client and amanda-plot, to 2 for
amanda-common and amanda-server.
Bug fix release and minor improvements:
new chg-iomega changer script.
amanda will not use a tape if it's label is not in the tapelist file.
amflush.c: Don't start a driver if nothing to flush.
amadmin.c: Call check_dumpuser() as soon as posible.
amadmin.c: Don't core dump if DUMPCYLE is too big.
dumper.c: Parse warning message.
The automatic truncation in gensolpkg doesn't work for packages which
have the same package name for the first 5-6 chars.
e.g. amanda-server and amanda-client would be named amanda and amanda.
Now, we add a SVR4_PKGNAME and use amacl for amanda-client and amase for
amanda-server.
All svr4 packages also have a vendor tag, so we have to reserve some chars
for this tag, which is normaly 3 or 4 chars. Thats why we can only use 6
or 5 chars for SVR4_PKGNAME. I used 5 for all the packages, to give the
vendor tag enough room.
All p5-* packages and a few other packages have now a SVR4_PKGNAME.
