Release Notes
===============
+v0.83
+=====
+
+Another Ceph development release! This has been a longer cycle, so
+there has been quite a bit of bug fixing and stabilization in this
+round. There is also a bunch of packaging fixes for RPM distros
+(RHEL/CentOS, Fedora, and SUSE) and for systemd. We've also added a new
+librados-striper library from Sebastien Ponce that provides a generic
+striping API for applications to code to.
+
+Upgrading
+---------
+
+* The experimental keyvaluestore-dev OSD backend had an on-disk format
+ change that prevents existing OSD data from being upgraded. This
+ affects developers and testers only.
+
+* mon-specific and osd-specific leveldb options have been removed.
+ From this point onward users should use 'leveldb_' generic options and add
+ the options in the appropriate sections of their configuration files.
+ Monitors will still maintain the following monitor-specific defaults:
+
+ leveldb_write_buffer_size = 32*1024*1024 = 33554432 // 32MB
+ leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB
+ leveldb_block_size = 64*1024 = 65536 // 64KB
+ leveldb_compression = false
+ leveldb_log = ""
+
+ OSDs will still maintain the following osd-specific defaults:
+
+ leveldb_log = ""
