Release Notes for Bacula 2.1.8

  Bacula code: Total files = 458 Total lines = 170,197 (*.h *.c *.in)

This Director and Storage daemon must be upgraded at the same time,
but they should be compatible with all 2.0.x File daemons, unless you
use some of the new features that affect the FD.  In other words, you should
not have to upgrade all your File daemons.  However, bat works only with
a 2.1.8 Director.

The major features are:
- First cut of bat (Bacula Administration Tool).  Note to build
  bat you must explicitly enable it on the ./configure line, you
  must have the Qt4 libraries loaded, and qmake and the other Qt4
  tools must be available.
- Red/Black restore in memory tree (500 times faster loading).
- Much faster insertion of attributes (somewhere around 10 times).
- The Regex Where code to allow easier relocation of restored files.
- Socket level heartbeat for all connections (untested).
- posix_fadvise() use in the FD to improve performance.
- Simpler locking in the SD in the reservation system.
- Much improved Volume reservation code that should eliminate most
  conflicts experienced in multiple drive autochangers.
- Detection of file size/date change during backup if enabled.
- New Recycle Pool feature.
- Efficient implementation of very large include/exclude lists.
- Volumes are no longer pruned during 'status dir'
- Pruning is now more efficient, and if a Volume is purged,
  during pruning, it is immediately discovered.

Other features or bug fixes:
- Fixed bugs: 856, 854, 845, 847, 846, 809, 772, 
  822, 825, 824, 808, 802, 797, 798, 795, 789, 791,

  766, 621, 761, 755, 750, 741, 747, 742, 744, and 743.
- Only the minumum number of volumes are pruned rather than
  all volumes in the pool.
- wx-console renamed to bwx-console
- gnome-console renamed to bgnome-console
- Migration preserves original job's FileSetId
- Spooling implemented for migration jobs.
- Config files can be read through a pipe, by specifying a leading |
  in front of the configuration path/filename.
- New memory command (bconsole) that will print the current Director's
  memory usage, and a in use buffer dump.
- Solaris door and event port files are no longer restored.
- Console name changed from *Console* to -Console- to accomodate Win32
  filename restrictions.  
- Corrected Win32 ftruncate bug.
- Additional version information added to Job reports.
- New -8 option for bsmtp to specify UTF-8 encoding type.
- bsmtp will no longer add < > to target (from, to, cc) if there
  is already a < in the target.
- Perfer Mounted Volumes extended to mean a volume that is being
  mounted by another job.
- Runscript timing set to same as version 1.38.11
- New TLS Allowed CN directive(s) permitted.
- New bconsole 'exec' command to run external script/command.
- Turn on FreeBSD/OpenBSD code to set EOT model on tape.
- Drop from root done before database is opened.
- database user and name can be configured with:
  --with-db-name=name --with-db-user=user
- turn on wait_for_drive in mtx-changer script.
- rework how bar codes are handled in mtx-changer script.
  This appears to have been an unreported bug.
- Updated nagios plugin supplied by Christian Masopust
- Better restricted console ACL checking.
- New Client Connect Wait directive in Storage daemon so that
  users can configure how long SD waits for FD connection.
- Bacula will no longer permit pruning of the currently running
  job (note, if other jobs are running, they may be pruned).
- Sockets are no longer restored.
- dbcheck works in 300K chunks so will typically run faster.
- Include/Exclude lists can now be efficiently handled for quite
  large sizes -- tens of thousands of entries.
- Several memory leaks in migration and database usage were fixed.
- New console keyword restoreclient, which specifies the client to
  which the restore will be sent. The client keyword specifies 
  the backup client. The restoreclient keyword is optional if it is
  not specified, the backup client will also be the restore client.
- The disk file size is now checked to ensure that it agrees with the
  catalog value before Bacula will append to the disk (same as tape
  and DVD).
