site-wide: Generate site content with a maintenance script.
When OVN 23.09 is released, we also will begin making more frequent point-releases of all other supported branches. Updating the website by hand for each release would be time-consuming and error-prone. This change uses a website update script to generate the website content. The script can be used for generating content for a new release or for updating content for previous releases, since the script re-generates content from scratch instead of actually updating the content.

|
|
||
| [Github link](https://github.com/ovn-org/ovn/releases/tag/v20.06.0) | ||
|
|
||
| Release Notes: | ||
| ``` | ||
| OVN v20.06.0 - 08 Jun 2020 | ||
| -------------------------- | ||
| - Added support for external_port_range in NAT table. | ||
| - ovn-controller no longer monitor the external_ids column from | ||
| the Chassis table. This was done to avoid having to do a flow | ||
| recalculation every time external systems wrote to this column. The | ||
| chassis configuration has now being moved to a new column called | ||
| "other_config". As a note, the configurations are still be written to | ||
| the external_ids column (but no longer triggers an alert) to | ||
| keep the backward compatibility with current systems that may be | ||
| reading it from that column but, this behavior will be removed | ||
| in the future. | ||
| - Added IPv6 Prefix Delegation support in OVN. | ||
| - OVN now uses OpenFlow 1.5. | ||
| - Added support to choose selection methods - dp_hash or | ||
| hash (with specified hash fields) for OVN load balancer | ||
| backend selection. This is incompatible with older versions. | ||
| Care should be taken while upgrading as the existing | ||
| load balancer traffic will be affected if ovn-controllers | ||
| are not stopped before uprading northd services. | ||
| - Added limited support for logical switches with multiple localnet ports. | ||
| The feature requires that no chassis has two or more physical networks | ||
| with localnet ports that belong to the same logical switch mapped. Routing | ||
| between the ports to be implemented by fabric. | ||
| - OVN Interconnection: | ||
| * Support for L3 interconnection of multiple OVN deployments with tunnels | ||
| managed by OVN. See instructions in | ||
| Documentation/tutorials/ovn-interconnection.rst. | ||
| ``` | ||

| -------------------------- | ||
| - Added packet marking support for traffic routed with | ||
| a routing policy. | ||
| - Added DHCPINFORM and DHCPRELEASE support in native | ||
| OVN DHCPv4 responder. | ||
| - Added support for DHCP domain search option (119) in native | ||
| OVN DHCPv4 responder. | ||
| - The nb_cfg column from the Chassis table in the OVN Southbound | ||
| database has been deprecated and is no longer updated. A new table | ||
| called Chassis_Private now contains the nb_cfg column which is updated | ||
| by incrementing the value in the NB_Global table, CMSes relying on | ||
| this mechanism should update their code to use this new table. | ||
| - Added support for external ip based NAT. Now, besides the logical ip, | ||
| external ips will also decide if a packet will be NATed or not. | ||
| - Added support for VXLAN encapsulation (not just for ramp/VTEP switches). | ||

|
|
||
| [Github link](https://github.com/ovn-org/ovn/releases/tag/v20.12.0) | ||
|
|
||
| Release Notes: | ||
| ``` | ||
| OVN v20.12.0 - 18 Dec 2020 | ||
| -------------------------- | ||
| - The "datapath" argument to ovn-trace is now optional, since the | ||
| datapath can be inferred from the inport (which is required). | ||
| - The obsolete "redirect-chassis" way to configure gateways has been | ||
| removed. See ovn-nb(5) for advice on how to update your config if needed. | ||
| - Add IPv4 iPXE support introducing "bootfile_name_alt" option to ovn dhcp | ||
| server. | ||
| - Support other_config:vlan-passthru=true to allow VLAN tagged incoming | ||
| traffic. | ||
| - Propagate currently processed SB_Global.nb_cfg in ovn-controller to the | ||
| local OVS DB integration bridge external_ids:ovn-nb-cfg. | ||
| - Support version pinning between ovn-northd and ovn-controller as an | ||
| option. If the option is enabled and the versions don't match, | ||
| ovn-controller will not process any DB changes. | ||
| - Add "fair" column in Meter table to allow multiple ACL logs to use the | ||
| same Meter while being rate-limited independently. | ||
| - New configuration option for northd 'options:use_logical_dp_groups=true' | ||
| to enable combining of logical flows by logical datapath. This should | ||
| significantly decrease size of a Southbound DB. However, in some cases, | ||
| it could have performance penalty for ovn-controller. Disabled by | ||
| default. | ||

|
|
||
| [Github link](https://github.com/ovn-org/ovn/releases/tag/v21.03.0) | ||
|
|
||
| Release Notes: | ||
| ``` | ||
| OVN v21.03.0 - 12 Mar 2021 | ||
| ------------------------- | ||
| - Support ECMP multiple nexthops for reroute router policies. | ||
| - BFD protocol support according to RFC880 [0]. Introduce next-hop BFD | ||
| availability check for OVN static routes. | ||
| [0] https://tools.ietf.org/html/rfc5880) | ||
| - Change the semantic of the "Logical_Switch_Port.up" field such that it is | ||
| set to "true" only when all corresponding OVS openflow operations have | ||
| been processed. This also introduces a new "OVS.Interface.external-id", | ||
| "ovn-installed". This external-id is set by ovn-controller only after all | ||
| openflow operations corresponding to the OVS interface being added have | ||
| been processed. | ||
| - ovn-ctl: Added new command line argument '--ovsdb-disable-file-column-diff' | ||
| to support ovsdb-server upgrades from version 2.14 and earlier to | ||
| 2.15 and later. See ovsdb(7) for more details. | ||
| - Add a new option to Load_Balancer.options, "hairpin_snat_ip", to allow | ||
| users to explicitly select which source IP should be used for load | ||
| balancer hairpin traffic. | ||
| - ovn-controller: Add configuration knobs, through OVS external-id | ||
| "ovn-limit-lflow-cache" and "ovn-memlimit-lflow-cache-kb", to allow | ||
| enforcing a limit for the size of the logical flow cache based on | ||
| maximum number of entries and/or memory usage. | ||
| - ovn-controller: Add lflow cache related memory reports. | ||

|
|
||
| Release Notes: | ||
| ``` | ||
| OVN v21.06.0 - 18 Jun 2021 | ||
| ------------------------- | ||
| - ovn-northd-ddlog: New implementation of northd, based on DDlog. This | ||
| implementation is incremental, meaning that it only recalculates what is | ||
| needed for the southbound database when northbound changes occur. It is | ||
| expected to scale better than the C implementation, for large deployments. | ||
| (This may take testing and tuning to be effective.) This version of OVN | ||
| requires DDLog 0.38. | ||
| - Introduce ovn-controller incremental processing engine statistics | ||
| - Introduced parallel processing in ovn-northd with the NB_Global config option | ||
| 'use_parallel_build' to enable it. It is disabled by default. | ||
| - Support vlan-passthru mode for tag=0 localnet ports. | ||
| - Support custom 802.11ad EthType for localnet ports. | ||
| - Add a new NB Global option - use_ct_inv_match with the default value of | ||
| true. If this is set to false, then the logical field - "ct.inv" will not | ||
| be used in the logical flow matches. CMS can consider setting this to | ||
| false, if they want to use smart NICs which don't support offloading | ||
| datapath flows with this field used. | ||
| - Introduce a new "allow-stateless" ACL verb to always bypass connection | ||
| tracking. The existing "allow" verb behavior is left intact. | ||
| - Added support in native DNS to respond to PTR request types. | ||
| - ovn-nbctl daemon mode is no longer considered experimental. | ||
| - Utilities: | ||
| * ovn-nbctl daemon mode is no longer considered experimental. | ||
| * ovn-sbctl now also supports daemon mode. | ||
| - Added support in native DNS to respond to PTR request types. | ||
| - New --dry-run option for ovn-northd and ovn-northd-ddlog. | ||
