+
+
+Version 2.2.0 rc0
+-----------------
+
+*(Released Fri, 30 Jul 2010)*
+
+Important change: the internal RPC mechanism between Ganeti nodes has
+changed from using a home-grown http library (based on the Python base
+libraries) to use the PycURL library. This requires that PycURL is
+installed on nodes. Please note that on Debian/Ubuntu, PycURL is linked
+against GnuTLS by default. cURL's support for GnuTLS had known issues
+before cURL 7.21.0 and we recommend using the latest cURL release or
+linking against OpenSSL. Most other distributions already link PycURL
+and cURL against OpenSSL. The command::
+
+ python -c 'import pycurl; print pycurl.version'
+
+can be used to determine the libraries PycURL and cURL are linked
+against.
+
+Other significant changes:
+
+- Rewrote much of the internals of the job queue, in order to achieve
+ better parallelism; this decouples job query operations from the job
+ processing, and it should allow much nicer behaviour of the master
+ daemon under load, and it also has uncovered some long-standing bugs
+ related to the job serialisation (now fixed)
+- Added a default iallocator setting to the cluster parameters,
+ eliminating the need to always pass nodes or an iallocator for
+ operations that require selection of new node(s)
+- Added experimental support for the LXC virtualization method
+- Added support for OS parameters, which allows the installation of
+ instances to pass parameter to OS scripts in order to customise the
+ instance
+- Added a hypervisor parameter controlling the migration type (live or
+ non-live), since hypervisors have various levels of reliability; this
+ has renamed the 'live' parameter to 'mode'
+- Added a cluster parameter ``reserved_lvs`` that denotes reserved
+ logical volumes, meaning that cluster verify will ignore them and not
+ flag their presence as errors
+- The watcher will now reset the error count for failed instances after
+ 8 hours, thus allowing self-healing if the problem that caused the
+ instances to be down/fail to start has cleared in the meantime
+- Added a cluster parameter ``drbd_usermode_helper`` that makes Ganeti
+ check for, and warn, if the drbd module parameter ``usermode_helper``
+ is not consistent with the cluster-wide setting; this is needed to
+ make diagnose easier of failed drbd creations
+- Started adding base IPv6 support, but this is not yet
+ enabled/available for use
+- Rename operations (cluster, instance) will now return the new name,
+ which is especially useful if a short name was passed in
+- Added support for instance migration in RAPI
+- Added a tool to pre-configure nodes for the SSH setup, before joining
+ them to the cluster; this will allow in the future a simplified model
+ for node joining (but not yet fully enabled in 2.2); this needs the
+ paramiko python library
+- Fixed handling of name-resolving errors
+- Fixed consistency of job results on the error path
+- Fixed master-failover race condition when executed multiple times in
+ sequence
+- Fixed many bugs related to the job queue (mostly introduced during the
+ 2.2 development cycle, so not all are impacting 2.1)
+- Fixed instance migration with missing disk symlinks
+- Fixed handling of unknown jobs in ``gnt-job archive``
+- And many other small fixes/improvements
+
+Internal changes:
+
+- Enhanced both the unittest and the QA coverage
+- Switched the opcode validation to a generic model, and extended the
+ validation to all opcode parameters
+- Changed more parts of the code that write shell scripts to use the
+ same class for this
+- Switched the master daemon to use the asyncore library for the Luxi
+ server endpoint
+
+
Version 2.2.0 beta 0
--------------------
- Added per-request RPC timeout
- RAPI now requires a Content-Type header for requests with a body (e.g.
``PUT`` or ``POST``) which must be set to ``application/json`` (see
- RFC2616 (HTTP/1.1), section 7.2.1)
+ :rfc:`2616` (HTTP/1.1), section 7.2.1)
- ``ganeti-watcher`` attempts to restart ``ganeti-rapi`` if RAPI is not
reachable
- Implemented initial support for running Ganeti daemons as separate
``EXP_SIZE_FD``
+Version 2.1.8
+-------------
+
+*(Released Tue, 16 Nov 2010)*
+
+Some more bugfixes. Unless critical bugs occur, this will be the last
+2.1 release:
+
+- Fix case of MAC special-values
+- Fix mac checker regex
+- backend: Fix typo causing “out of range” error
+- Add missing --units in gnt-instance list man page
+
+
+Version 2.1.7
+-------------
+
+*(Released Tue, 24 Aug 2010)*
+
+Bugfixes only:
+ - Don't ignore secondary node silently on non-mirrored disk templates
+ (issue 113)
+ - Fix --master-netdev arg name in gnt-cluster(8) (issue 114)
+ - Fix usb_mouse parameter breaking with vnc_console (issue 109)
+ - Properly document the usb_mouse parameter
+ - Fix path in ganeti-rapi(8) (issue 116)
+ - Adjust error message when the ganeti user's .ssh directory is
+ missing
+ - Add same-node-check when changing the disk template to drbd
+
+
+Version 2.1.6
+-------------
+
+*(Released Fri, 16 Jul 2010)*
+
+Bugfixes only:
+ - Add an option to only select some reboot types during qa/burnin.
+ (on some hypervisors consequent reboots are not supported)
+ - Fix infrequent race condition in master failover. Sometimes the old
+ master ip address would be still detected as up for a short time
+ after it was removed, causing failover to fail.
+ - Decrease mlockall warnings when the ctypes module is missing. On
+ Python 2.4 we support running even if no ctypes module is installed,
+ but we were too verbose about this issue.
+ - Fix building on old distributions, on which man doesn't have a
+ --warnings option.
+ - Fix RAPI not to ignore the MAC address on instance creation
+ - Implement the old instance creation format in the RAPI client.
+
+
+Version 2.1.5
+-------------
+
+*(Released Thu, 01 Jul 2010)*
+
+A small bugfix release:
+ - Fix disk adoption: broken by strict --disk option checking in 2.1.4
+ - Fix batch-create: broken in the whole 2.1 series due to a lookup on
+ a non-existing option
+ - Fix instance create: the --force-variant option was ignored
+ - Improve pylint 0.21 compatibility and warnings with Python 2.6
+ - Fix modify node storage with non-FQDN arguments
+ - Fix RAPI client to authenticate under Python 2.6 when used
+ for more than 5 requests needing authentication
+ - Fix gnt-instance modify -t (storage) giving a wrong error message
+ when converting a non-shutdown drbd instance to plain
+
+
+Version 2.1.4
+-------------
+
+*(Released Fri, 18 Jun 2010)*
+
+A small bugfix release:
+
+ - Fix live migration of KVM instances started with older Ganeti
+ versions which had fewer hypervisor parameters
+ - Fix gnt-instance grow-disk on down instances
+ - Fix an error-reporting bug during instance migration
+ - Better checking of the ``--net`` and ``--disk`` values, to avoid
+ silently ignoring broken ones
+ - Fix an RPC error reporting bug affecting, for example, RAPI client
+ users
+ - Fix bug triggered by different API version os-es on different nodes
+ - Fix a bug in instance startup with custom hvparams: OS level
+ parameters would fail to be applied.
+ - Fix the RAPI client under Python 2.6 (but more work is needed to
+ make it work completely well with OpenSSL)
+ - Fix handling of errors when resolving names from DNS
+
+
