ChangeLog

2.1.12:
  * Add "import" command to cvmfs_server that transforms a 2.0
    repository into a 2.1 repository (Stratum 0)
  * Drastically improved performance of copying the inode
    tracker
  * Add pin command to cvmfs_talk
  * Fix reading from socket in talk thread
  * Add "nameserver set" command to cvmfs_talk
  * Fix various issues with reading of chunked files
  * Decrease memory consumption of the inode tracker
  * Remove trailing empty attribute in listattr callback
  * Make repositories replicatable by default
  * Safe guard against concurrent snapshot processes
  * Drop config.sh dependency from cvmfs_server
  * Experimental support for repository tags (named snapshots).
    Allows to mount a specific repository version and to rollback
    and re-publish previous repository states.

2.1.11:
  * Improve logging for whitelist expiry and fqrn errors
  * Add network path reset within the same proxy group
    (re-balance proxies)
  * Add network path reset for failover hosts
  * Add missing execmod SELinux exception for 32bit SL6
  * Fix occasional hangs of gdb when generating stack traces
  * Improve host/proxy failover logging
  * Fix host failover
  * Perform a host failover instead of a proxy failover 
    on HTTP 502, 504 errors
  * Add experimental support for "micro-syslog" implementation that
    writes syslog messages to a file.  Add CVMFS_USYSLOG parameter
    to specify the destination file.
  * Distinguish information, warning, and error records when
    writing to syslog
  * Add -march=i686 to CFLAGS and CXXFLAGS for 32bit builds 
  * Add CVMFS_MOUNT_RW switch parameter.  A read/write mount point
    can workaround problematic open flags (O_RDWR, O_TRUNC, ...)
  * Remove unused CVMFS_64BIT_INODES parameter
  * Avoid __sync_fetch_and_add on 64bit integers with a negative
    offset.  This breaks on 32bit systems.  It affects the counter
    for active file system calls in the loader.
  * SLES11 build system compatibility fixes

2.1.10:
  * Use continuous inodes on inode generation change instead of
    fixed bit fields.  This increases the usable inode space.
