  Thanks to Meno for this idea.
- Make some modifications to satisfy VC++.
- Apply Martin Simmons' second patch to compat.cpp to fix the line
  I previously missed.

  messages is immutable bit is set.
- Turn off heartbeat in FD when -s is given so that we can 
  debug without a flood of signals.

- Add a number of "%s" in editing database errors -- security issue.
- Ensure that the NumVols is incremented and decremented in the
  pool record when Volumes are created or deleted.
- Cleanup error handling when labeling a tape. If vol was read-only,
  the device would still be marked as having found a label.

  this will fix the problem of noticing files have been moved
  into the save path after a Full save.
- Fix bug in "status dir" where not all entries are listed.

- Optimize a couple of insertions in binary_insert of dlists.

Release 1.35.0 08 July 2004:
- Apply Christopher Hull's const patch for PostgreSQL
- Add code to block.c to detect if block header is destroyed.
- Add debug code for memset checking for zeroing 1900-3000 bytes
  which is what happened to the block headers.
- If block header is destroyed, read the next block. Probably
  should return with new status similar to the SHORT block 
  return.
- Add more debug info to bls for bad blocks.
- More implementation of DCRs.
- Eliminate argument passing in SD by using dcr.
- More int->bool conversions.
- Add file:block to a number of read/write error messages.
- More int -> bool conversions.
- Modify the SD piece by piece to use DCRs everywhere.
- Cleanup some printout for query command. 
- Fix typo in cats/mysql.c
- Work on cleaning up tape driver a bit (use bools, better calling
  sequences).
- Attempt to fix multi-Volume disk backup. Needs to be tested.
- Add Regular expressions to FileSet options.
- Correct configure.in to use ${MAKE} for doing the dependencies.
- Make MySQL and PostgreSQL try for 30 seconds to connect before
  giving up.  
- Correct Gnome 1.4 Makefile to build without cats library.
- Correct a crash reported (with patch) by Jonathan Soong 
  when attempting to backup an ACL on a symlinked file.
- Fixed an off by one bug in the new resources pointer code.      
  res_head array was one too small.
- Added Errors to last_job list. This allows detecting jobs
  that terminated in a warning.
- Implement setting the Win32 icon to yellow instead of red
  when the job terminated OK but with warnings.
- Fix the Win32 makefile and VC project file. The links were
  not including the Win32 dlls.      
- Delete some old Win32 code that was turned off.
- Eliminate a few more Win32 compiler warnings.
- Reduce the output produced by NIS (Win32 install builder).
- Simplify some of the #ifdefing in compat.h
- Rewrite spooling error handling when I/O error occurs. It is
  a bit tricky, requiring to truncate the file so that a despooling
  will work correctly. Needs to be tested.
- Make better subroutines for setting up for a new job.
- Start putting all DB ids on #defines (going to 64 bits).
- Fix gnome-console Makefile.in to work again.
- All "level=Incremental/Decremental" to the estimate command. This
  required some re-arrangement of subroutines at a fairly low level.
- Apply Piotr Jaworski's patch (patch-r-status.diff) to update the
  catalog status when a backup job starts running.
- Add (char*) cast to readline call in console.c for old readlines.
- Copy Makefile.in from gnome2-console to gnome-console (to eliminate
  need for cats library).
- Modify spooling code to handle write error (e.g. spooling disk full)
  more gracefully. Previously despooling would fail.
- Reduce casting in smartall.c a bit and add counters for 
  bytes, max_bytes, buffers and max_buffers.
- Fixed reload algorithm to stack both job end callback and the
  table id.
- Fixed the orphaned buffer after reload (job_end_push had to be
  destroyed.
- Destroy cond var (jcr->term_wait) only if initialized.
- Sort the Scheduled Jobs list by start-time, priority.
- Implement resources on a pointer.
- Fix Gnome console crash on up/down arrow with no history.
- Finish first cut of SIGHUP code. To make really work need res
  on a single pointer rather than in fixed memory.
- Fix a number of places in query.sql where multiple JobIds are
  printed (due to JobMedia records).
- Add new query: List jobs on Volume given Volume name.   
- Correct socket close on Win32 in bnet.c (in addition to compat.cpp).
  Caused fd leak in Win32 for each connection.
- Remove vol labeled test in askdir update_volume_info so that non-labeled
  Volume in catalog can be marked in error.
- Close socket in SD when connection rejected. Caused fd leaks.
- Initialize job_start_wait cond variable after every new_jcr() otherwise
  NetBSD gets error in library when trying to delete it without being inited.
- Fix typo (9 instead of 0) return status in write_new_volume_label.
- Fix mount.c to call routine that correctly marks a volume in error.
- Move code to rewrite volume label to subroutine -- a bit cleaner.
- Finish implementation and testing of new restore tree code.
- Implement feedback while tree is loading.
- Eliminate printing INFO message in UpdateDB (cats) -- it generates
  "false" error messages.
- Eliminate some GTK error messages when running the Gnome2 console.
- Begin restructuring tree.c for inclusion of the binary_insert()
  routine.         
- Apply Peter Eriksson's lib file order changes in linking for IRIX.
- Abort configure if Internal is  selected as the database.
- Add testimonials to the Web page
- Add the bugs list to the Web page "lists".
- Clarify the English in SuSE and Slackware when SD not running.
- Applied another extern "C" patch from Peter Eriksson.
- Fixed a bunch of VC warning messages.
- Applied the patches sent by Andreas Jellinghaus: build Gnome and  
  wx-console in client-only build if configured; add ./configure option
  to permit setting of sbin modes -- default is 0745 as before; remove
  cats library from Gnome console build; remove old version from Gnome
  About box. Thanks Andreas.
- Applied Peter Eriksson's const changes to the source code. Thanks Peter.
- Implemented a binary_insert() method for dlists -- intended to be used
  in the restore tree routines.
- Turned on my bsscanf() code, which replaces sscanf() by my routines, which
  are a subset of sscanf() used by Bacula, but which have known 32/64 bit
  behavior rather than vendor dependent !@#$%*.
