Technical notes on version 2.1
General:
+Release: 2.1.20 beta
+20Jun07
+kes Fixed bug #886 (multidrive autochanger: SD doesn't use drive with
+ loaded tape but uses first drive).
+kes Fixed bug #807 Restore encrypted backup failed on Windows 2003
+ This was indeed a Win32 issue.
+19Jun07
+kes Simplify search of autochanger for in-use Volume.
+kes Fix exit condition of check for in-use volume. kes Remove
+ inappropriate my_postgresql_free_result() in db_close()
+ routine.
+kes Fix bad return in FD when encryption signature not found.
+ Probably caused a crash.
+kes Inhibit missing encryption signature error messages for
+ file types where no signature computed.
+kes Correct inverted check on autochanger in reservation system.
+kes Tweak debug code in autochanger reservation.
+18Jun07
+kes Add some additional locking in the cats directory in subroutines
+ that modify packet variables called from batch insert.
+kes Rework how dcrs are allocated. new_dcr() can now be called
+ with an existing pointer, and it will simply clean it up.
+ This allows the reservation system to test various different
+ devices, and will permit easy device changes.
+kes A bunch of changes all over to handle new new_dcr() calling
+ sequence.
+kes Work more on the Volume management in the SD. Remember Volumes
+ for tape drives and for autochangers (even virtual disk changers).
+kes When looking at the Volume list to reserve a drive, handle
+ autochanger names correctly by interating through the changer
+ devices. Also call the Director to see if a Volume is suitable
+ for the current job.
+kes Fix some bugs in bscan. Make sure all media records are written.
+ Make sure that valid JobMedia records are written for disk files.
+ Previously they were completely wrong.
+kes Move source tar files for depkgs-mingw32 to www.bacula.org so
+ that the URLs don't change and so that the developers will all
+ work off the same copy. Rebuild from scrach.
+kes Upgrade Win32 SQLite3 from 3.3.8 to 3.3.17.
+
Release: 2.1.18 beta
16Jun07
kes Fix seg fault in FD from incorrect digest size.
