Release v0.11.2

Fixed

• Send necessary updates to Antrea Agents when a Pod's IP address is updated, as otherwise NetworkPolicies are not enforced correctly. (#1808, @Dyanngg @tnqn)
• On Antrea Agent restart, ensure that OpenFlow priorities are assigned correctly for NetworkPolicy rules, and that rules with the same tier and priority are assigned the same OpenFlow priority. (#1841, @Dyanngg)
• Do not release the OpenFlow priority assigned to a NetworkPolicy rule in case of a transient error when installing the corresponding flows, if other rules are using the same OpenFlow priority. (#1844, @Dyanngg)
• Do not delete Endpoint flows when an Endpoint is no longer used for a specific Service (or if a Service is deleted) if these flows are still required by another Service. (#1815, @weiqiangt)
• Fix bugs in IPv6 AntreaProxy implementation, notably for flow "hairpinning" and ServiceAffinity support. (#1713, @lzhecheng)
• Support non-standardized CIDRs (CIDRs for which some address bits may not have been masked off as per the prefix length) in NetworkPolicies. (#1767, @tnqn)
• Fix minimum required Linux Kernel version (4.6) in documentation. (#1757, @hongliangl)
• Fix Agent crash when creating an Antrea-native policy with a "drop" action, while the NetworkPolicyStats feature is enabled. (#1606, @ceclinux)
• Fix Traceflow when Antrea-native policies are created with a "drop" action. (#1602, @gran-vmv @lzhecheng)
• Fix Agent crash when enabling NetworkPolicyStats and Traceflow feature together and creating an Antrea-native policy with a "drop" action. (#1615, @tnqn)
• When the destination is a Service in a Traceflow request, do not overwrite the default TCP SYN flag (needed for the packet to be processed by AntreaProxy correctly) unless the user explicitly provided a non-zero value. (#1602, @gran-vmv @lzhecheng)
• Improve handling of transient OVS errors when installing flows for policy rules in the Agent, by ensuring that retries are executed correctly. (#1667, @tnqn)
