##### 2.0.2 (July 8, 2026)
SECURITY:

* Upgrade alpine base image version to 3.24 to address [CVE-2026-41989], [ALPINE-CVE-2026-2100]. [[GH-23711](https://github.com/hashicorp/consul/issues/23711)]
* dependency: Upgrade Serf and Memberlist to use the latest versions. [[GH-23704](https://github.com/hashicorp/consul/issues/23704)]
* xds: Return errors when injecting the L4 intention (RBAC) filter or the mTLS transport socket onto an inbound public listener, so the listener is not served without intention enforcement or mTLS. [[GH-23686](https://github.com/hashicorp/consul/issues/23686)]

FEATURES:

* config-entry(api-gateway): (Enterprise only) Add ExtAuthzFilter to HTTPRoute Filters and gateway-wide ExtAuthz toggle to the api-gateway config entry [[GH-23703](https://github.com/hashicorp/consul/issues/23703)]
* config-entry: (Enterprise only) Addition of External Processor (ext_proc) Envoy Extension support to api-gateway and connect-proxy [[GH-23705](https://github.com/hashicorp/consul/issues/23705)]

IMPROVEMENTS:

* ci: upgrade GitHub Actions that used the deprecated Node 20 runtime to Node 24, and restore GOTOOLCHAIN=auto after setup-go so backward-compatibility and integration test lanes resolve the correct Go toolchain. [[GH-23687](https://github.com/hashicorp/consul/issues/23687)]
* connect: update support for nomad and vault version to v2.0.3 [[GH-23624](https://github.com/hashicorp/consul/issues/23624)]

KNOWN ISSUES:

* consul-k8s: In setups using consul OSS version, consul-k8s-connect-injector fails to come up because of a missing CRD RouteExtProc. A new version(2.0.2-oss) of consul helm chart is released to resolve this issue. Use the Chart version '2.0.2-oss' for OSS distribution of consul of this release v2.0.2.

SECURITY:

* connect: Upgrade envoy version to 1.37.2 and newer versions [[GH-23469](https://github.com/hashicorp/consul/pull/23469)]
* go: Upgrade go version to 1.26 [[GH-23493](https://github.com/hashicorp/consul/pull/23493)]
* agent: Increased default HTTP server timeouts to prevent breaking long-polling blocking queries. `read_timeout` and `write_timeout` are now set to 15 minutes (up from 30 seconds), while `read_header_timeout` (10s) and `idle_timeout` (120s) still provide protection against Slowloris attacks. All timeouts remain configurable via the `http_config` block. [[GH-23267](https://github.com/hashicorp/consul/issues/23267)]
* api-gateway, terminating-gateway: Apply HTTP request path normalization on api-gateway and terminating-gateway HTTP listeners to prevent L7 intention RBAC bypass via non-normalized paths (CVE-2024-10005). [[GH-23534](https://github.com/hashicorp/consul/issues/23534)]

Alpine 3.23 stable does not yet carry the patched version. [[GH-23750](https://github.com/hashicorp/consul/issues/23750)]
* docker: Update to UBI base image to 9.8 for fixing [[CVE_2026-2100](https://access.redhat.com/security/cve/cve-2026-2100)] [[GH-23588](https://github.com/hashicorp/consul/issues/23588)]

FEATURES:

* **(Enterprise Only)** update to go-licensing/v4 and go-census/v3 inorder to adapt to new licenses of PAO.
* Global Rate Limiter: **(Enterprise Only)** a new "rate-limit" config entry kind that enables dynamic, cluster-wide RPC rate limiting stored in Raft and automatically replicated to all servers. This allows operators to apply or adjust global rate limits at runtime without restarting Consul servers — a critical capability for emergency scenarios where the cluster is under excessive load.
* api-gateway: Added SDS certificate support for API Gateway listeners, including listener-level default TLS certificates and HTTP/TCP route service TLS SDS overrides. Service overrides inherit the listener SDS cluster when omitted, and gateway validation/xDS generation now rejects conflicting override mappings to keep certificate selection deterministic. [[GH-23354](https://github.com/hashicorp/consul/pull/23354)]
* api-gateway: add support for gateway-level default upstream limits and route service-level limit overrides for MaxConnections, MaxPendingRequests, and MaxConcurrentRequests. [[GH-23396](https://github.com/hashicorp/consul/pull/23396)]
* api: Added new API "/v1/internal/rpc/methods" that lists all RPC method names. Requires an operator:read ACL token. This is useful when users want to configure rate limits that exclude specific RPC endpoints. [[GH-23329](https://github.com/hashicorp/consul/pull/23329)]
* ca: **(Enterprise Only)** Added new Connect CA provider for Cyberark WIM (connect.ca_provider = "pan-distributed-issuer"), enabling Consul to issue certificates through Cyberark WIM.
* server: **(Enterprise Only)** add stable cluster identity and leader-gated global registry sync for service summary publishing.
* telemetry: **(Enterprise Only)** Product telemetry for self-managed Consul with anonymous, opt-in usage reporting.

- Permalink: https://whatsnew.fyi/product/consul/releases/v2.0.0-rc2
- Labels: Pre-release

- **security** — Increased default HTTP server timeouts to prevent breaking long-polling blocking queries, with read_timeout and write_timeout now set to 15 minutes (up from 30 seconds), while read_header_timeout (10s) and idle_timeout (120s) still provide protection against Slowloris attacks

- **security** — Update ubi base image to ubi9-minimal:9.7
- **security** — Fixed Consul transaction endpoint authorization bypasses where service and check mutations could be authorized using request-provided names while applying changes by ID, including a bypass using the reserved consul service name
- **fixed** — Fixed issue with mesh-gateway in remote mode on AWS EKS where DNS hostnames are assigned to AWS NLBs instead of IPs by skipping EDS load assignment for non-peer remote mesh gateway targets with hostname based gateways to keep CDS/EDS in sync
- **fixed** — Resolve service subsets for routes during API gateway discovery chain synthesis

##### 2.0.0-rc2 (May 15, 2026)

SECURITY:

[[GH-12716](https://github.com/hashicorp/consul/issues/12716)]

BUG FIXES:

* XDS: Fixes issue with mesh-gateway in remote mode on AWS EKS, as DNS hostnames are assigned to AWS NLBs instead of IPs and envoy's EDS endpoint validation expects address to be an IP. Now EDS load assignment is skipped for non-peer remote mesh gateway targets with hostname based gateways keeping CDS/EDS in sync. [[GH-23543](https://github.com/hashicorp/consul/issues/23543)]
* api-gateway: resolve service subsets for routes during API gateway discovery chain synthesis. [[GH-23294](https://github.com/hashicorp/consul/issues/23294)]

IMPROVEMENTS:

* agent: **(Enterprise Only)** Add eventually-consistent background cache for Enterprise usage metrics, reducing GET /v1/operator/usage latency from O(P*N*K) to O(1) and lowering CPU/memory pressure during high-frequency scraping via a watch-driven maintainer goroutine.
