+- Support ``ssh-agent`` again when adding nodes
+- Many additional bugfixes
+
+
+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
+--------------------
+
+*(Released Thu, 17 Jun 2010)*
+
+- Added tool (``move-instance``) and infrastructure to move instances
+ between separate clusters (see :doc:`separate documentation
+ <move-instance>` and :doc:`design document <design-2.2>`)
+- 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
+ :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
+ users, see configure-time flags ``--with-user-prefix`` and
+ ``--with-group-prefix`` (only ``ganeti-rapi`` is supported at this
+ time)
+- Instances can be removed after export (``gnt-backup export
+ --remove-instance``)
+- Self-signed certificates generated by Ganeti now use a 2048 bit RSA
+ key (instead of 1024 bit)
+- Added new cluster configuration file for cluster domain secret
+- Import/export now use SSL instead of SSH
+- Added support for showing estimated time when exporting an instance,
+ see the ``ganeti-os-interface(7)`` manpage and look for
+ ``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
+
+
+Version 2.1.3
+-------------
+
+*(Released Thu, 3 Jun 2010)*
+
+A medium sized development cycle. Some new features, and some
+fixes/small improvements/cleanups.
+
+Significant features
+~~~~~~~~~~~~~~~~~~~~
+
+The node deamon now tries to mlock itself into memory, unless the
+``--no-mlock`` flag is passed. It also doesn't fail if it can't write
+its logs, and falls back to console logging. This allows emergency
+features such as ``gnt-node powercycle`` to work even in the event of a
+broken node disk (tested offlining the disk hosting the node's
+filesystem and dropping its memory caches; don't try this at home)
+
+KVM: add vhost-net acceleration support. It can be tested with a new
+enough version of the kernel and of qemu-kvm.
+
+KVM: Add instance chrooting feature. If you use privilege dropping for
+your VMs you can also now force them to chroot to an empty directory,
+before starting the emulated guest.
+
+KVM: Add maximum migration bandwith and maximum downtime tweaking
+support (requires a new-enough version of qemu-kvm).
+
+Cluster verify will now warn if the master node doesn't have the master
+ip configured on it.
+
+Add a new (incompatible) instance creation request format to RAPI which
+supports all parameters (previously only a subset was supported, and it
+wasn't possible to extend the old format to accomodate all the new
+features. The old format is still supported, and a client can check for
+this feature, before using it, by checking for its presence in the
+``features`` RAPI resource.
+
+Now with ancient latin support. Try it passing the ``--roman`` option to
+``gnt-instance info``, ``gnt-cluster info`` or ``gnt-node list``
+(requires the python-roman module to be installed, in order to work).
+
+Other changes
+~~~~~~~~~~~~~
+
+As usual many internal code refactorings, documentation updates, and
+such. Among others:
+
+ - Lots of improvements and cleanups to the experimental Remote API
+ (RAPI) client library.
+ - A new unit test suite for the core daemon libraries.
+ - A fix to creating missing directories makes sure the umask is not
+ applied anymore. This enforces the same directory permissions
+ everywhere.
+ - Better handling terminating daemons with ctrl+c (used when running
+ them in debugging mode).
+ - Fix a race condition in live migrating a KVM instance, when stat()
+ on the old proc status file returned EINVAL, which is an unexpected
+ value.
+ - Fixed manpage checking with newer man and utf-8 charachters. But now
+ you need the en_US.UTF-8 locale enabled to build Ganeti from git.
+
+
+Version 2.1.2.1
+---------------
+
+*(Released Fri, 7 May 2010)*
+
+Fix a bug which prevented untagged KVM instances from starting.
+
+
+Version 2.1.2
+-------------
+
+*(Released Fri, 7 May 2010)*
+
+Another release with a long development cycle, during which many
+different features were added.
+
+Significant features
+~~~~~~~~~~~~~~~~~~~~
+
+The KVM hypervisor now can run the individual instances as non-root, to
+reduce the impact of a VM being hijacked due to bugs in the
+hypervisor. It is possible to run all instances as a single (non-root)
+user, to manually specify a user for each instance, or to dynamically
+allocate a user out of a cluster-wide pool to each instance, with the
+guarantee that no two instances will run under the same user ID on any
+given node.
+
+An experimental RAPI client library, that can be used standalone
+(without the other Ganeti libraries), is provided in the source tree as
+``lib/rapi/client.py``. Note this client might change its interface in
+the future, as we iterate on its capabilities.
+
+A new command, ``gnt-cluster renew-crypto`` has been added to easily
+replace the cluster's certificates and crypto keys. This might help in
+case they have been compromised, or have simply expired.
+
+A new disk option for instance creation has been added that allows one
+to "adopt" currently existing logical volumes, with data
+preservation. This should allow easier migration to Ganeti from
+unmanaged (or managed via other software) instances.
+
+Another disk improvement is the possibility to convert between redundant
+(DRBD) and plain (LVM) disk configuration for an instance. This should
+allow better scalability (starting with one node and growing the
+cluster, or shrinking a two-node cluster to one node).
+
+A new feature that could help with automated node failovers has been
+implemented: if a node sees itself as offline (by querying the master
+candidates), it will try to shutdown (hard) all instances and any active
+DRBD devices. This reduces the risk of duplicate instances if an
+external script automatically failovers the instances on such nodes. To
+enable this, the cluster parameter ``maintain_node_health`` should be
+enabled; in the future this option (per the name) will enable other
+automatic maintenance features.
+
+Instance export/import now will reuse the original instance
+specifications for all parameters; that means exporting an instance,
+deleting it and the importing it back should give an almost identical
+instance. Note that the default import behaviour has changed from
+before, where it created only one NIC; now it recreates the original
+number of NICs.
+
+Cluster verify has added a few new checks: SSL certificates validity,
+/etc/hosts consistency across the cluster, etc.
+
+Other changes
+~~~~~~~~~~~~~
+
+As usual, many internal changes were done, documentation fixes,
+etc. Among others:
+
+- Fixed cluster initialization with disabled cluster storage (regression
+ introduced in 2.1.1)
+- File-based storage supports growing the disks
+- Fixed behaviour of node role changes
+- Fixed cluster verify for some corner cases, plus a general rewrite of
+ cluster verify to allow future extension with more checks
+- Fixed log spamming by watcher and node daemon (regression introduced
+ in 2.1.1)
+- Fixed possible validation issues when changing the list of enabled
+ hypervisors
+- Fixed cleanup of /etc/hosts during node removal
+- Fixed RAPI response for invalid methods
+- Fixed bug with hashed passwords in ``ganeti-rapi`` daemon
+- Multiple small improvements to the KVM hypervisor (VNC usage, booting
+ from ide disks, etc.)
+- Allow OS changes without re-installation (to record a changed OS
+ outside of Ganeti, or to allow OS renames)
+- Allow instance creation without OS installation (useful for example if
+ the OS will be installed manually, or restored from a backup not in
+ Ganeti format)
+- Implemented option to make cluster ``copyfile`` use the replication
+ network
+- Added list of enabled hypervisors to ssconf (possibly useful for
+ external scripts)
+- Added a new tool (``tools/cfgupgrade12``) that allows upgrading from
+ 1.2 clusters
+- A partial form of node re-IP is possible via node readd, which now
+ allows changed node primary IP
+- Command line utilities now show an informational message if the job is
+ waiting for a lock
+- The logs of the master daemon now show the PID/UID/GID of the
+ connected client
+
