+
+**The changes marked with :warning: are not backward compatible.**
+
+### Change
+
+- :warning: feat(upstream): verify the upstream certificate against 
configurable CAs. `upstream.tls.verify` was only read by the `kafka` scheme and 
is now honoured for `https` and `grpcs` as well, so an upstream that already 
carried `verify: true` starts rejecting a certificate it cannot validate; 
`tls.ca_certs` picks the trust anchors per upstream 
[#13863](https://github.com/apache/apisix/pull/13863)
+- :warning: feat: label WebSocket sessions with `request_type=websocket`. A 
request answered with `101 Switching Protocols` moves from `traditional_http` 
to `websocket` in `apisix_http_status`, `apisix_http_latency` and 
`apisix_bandwidth`, so existing queries, dashboards and alerts must account for 
the new label value [#13909](https://github.com/apache/apisix/pull/13909)
+- :warning: fix(openid-connect): validate the introspection issuer. With an 
explicit `claim_validator.issuer.valid_issuers`, a successful remote 
introspection response must now carry a string `iss` matching one of them, or 
the request is rejected with 401; omit the allowlist to keep the previous 
behavior [#13916](https://github.com/apache/apisix/pull/13916)
+- :warning: fix(feishu-auth, dingtalk-auth): bind the authorization code to 
the session that started the login. The query-string code path now requires a 
`state` that matches the session, so `redirect_uri` has to carry it through the 
login page and back; a user mid-flow across the upgrade gets a 401 and succeeds 
on retry. The header code path (`X-Feishu-Code` / `X-DingTalk-Code`) is 
unchanged [#13806](https://github.com/apache/apisix/pull/13806)
+- :warning: fix(batch-requests): bound aggregated response bodies. New 
`max_response_body_size` (1 MiB) and `max_response_body_size_total` (10 MiB) 
plugin metadata; a pipeline above either limit now returns 502 instead of the 
full aggregate [#13906](https://github.com/apache/apisix/pull/13906)
+- :warning: fix(basic-auth): reject an empty consumer password. `password` 
requires `minLength: 1`, so the Admin API rejects an empty value and a consumer 
already stored with one fails closed with 401 
[#13884](https://github.com/apache/apisix/pull/13884)
+- :warning: fix(ai-proxy-multi): reject instances that share a name. 
`instance.name` is the instance identity across the balancer, the health 
checker, `ai-rate-limiting` and `semantic_opts.fallback`, so a route whose 
instances share a name is now rejected on write and dropped on reload 
[#13851](https://github.com/apache/apisix/pull/13851)
+- :warning: fix(workflow): reject invalid case expressions and missing action 
conf. A `case` value that was silently accepted and matched every request is 
now a schema error [#13862](https://github.com/apache/apisix/pull/13862)
+- :warning: fix(control): always report healthcheck nodes as a JSON array. 
`nodes` and the top-level list of `/v1/healthcheck` are `[]` instead of `{}` 
when empty [#13891](https://github.com/apache/apisix/pull/13891)
+
+### Core
+
+- feat(stream): support TLS passthrough on the stream proxy, so a stream route 
can pick its upstream from the SNI in the prereaded ClientHello and still 
forward the session encrypted 
[#13912](https://github.com/apache/apisix/pull/13912)
+- feat(stream): match a stream route by several SNIs through the new `snis` 
field, mutually exclusive with `sni` 
[#13911](https://github.com/apache/apisix/pull/13911)
+- feat(websocket): add the `ws`/`wss` upstream scheme, which proxies frames 
through APISIX itself and exposes the `ws_handshake`, `ws_client_frame`, 
`ws_upstream_frame` and `ws_close` plugin phases plus the `core.websocket` API 
[#13939](https://github.com/apache/apisix/pull/13939)
+- feat(upstream): slow start for newly observed upstream nodes via 
`warm_up_conf` [#13941](https://github.com/apache/apisix/pull/13941)
+- feat: improve API-driven standalone update reliability: workers report a 
per-entity configuration digest, `PUT /apisix/admin/configs` accepts a `wait` 
parameter and answers 200 once every worker has loaded the configuration (202 
otherwise), and the shdict format carries the digest outside the JSON 
[#13904](https://github.com/apache/apisix/pull/13904)
+- feat(control-api): report the health checks a plugin owns, so 
`ai-proxy-multi` instance checkers show up in `/v1/healthcheck` 
[#13899](https://github.com/apache/apisix/pull/13899)
+- chore: upgrade lua-resty-dns-client to 7.1.2, fixing `finalCacheOnly` so a 
CNAME chain no longer fails with `empty record received` when the answer 
carries an EDNS(0) OPT record or is not in chain order 
[#13875](https://github.com/apache/apisix/pull/13875)
+- fix(etcd): watch from the revision the configuration was read at, so a write 
made while APISIX is starting is no longer lost 
[#13917](https://github.com/apache/apisix/pull/13917)
+- fix(etcd): check etcd availability before starting the watcher, so config 
objects do not wait on a watcher that never connected 
[#13934](https://github.com/apache/apisix/pull/13934)
+- fix(etcd): do not block writes when the deployment role cannot be read 
[#13885](https://github.com/apache/apisix/pull/13885)
+- fix(standalone): stop aborting stream connections before the first config 
arrives [#13855](https://github.com/apache/apisix/pull/13855)
+- fix(standalone): harden the declarative configuration paths: validate the 
shape of the request body instead of 500ing, log the parser error rather than 
the body (which can carry credentials and private keys), check a stream route's 
`superior_id` self reference during validation, and guard null deployment 
sections in the CLI [#13886](https://github.com/apache/apisix/pull/13886)
+- fix(plugin): align unavailable plugin handling: reject unknown plugin names 
before persistence, keep data-plane loading tolerant of them, and warn when one 
is skipped [#13928](https://github.com/apache/apisix/pull/13928)
+- fix: preserve servlet upstream URI boundaries by encoding the original path 
before proxying when servlet-style normalization is enabled 
[#13914](https://github.com/apache/apisix/pull/13914)
+- fix: write `request_type=websocket` through `ctx.var`, so a plugin that 
resolved `$request_type` before the upgrade does not leave the cached value at 
`traditional_http` [#13915](https://github.com/apache/apisix/pull/13915)
+
+### Plugins
+
+- feat: add the `openapi-to-mcp` plugin, serving an HTTP API to MCP clients 
from its OpenAPI document over Streamable HTTP and HTTP+SSE 
[#13942](https://github.com/apache/apisix/pull/13942)
+- feat(websocket): add the `websocket-proxy` plugin to customize proxy 
behaviors, starting with `client_max_payload_len` / `upstream_max_payload_len` 
for `ws`/`wss` upstreams [#13972](https://github.com/apache/apisix/pull/13972)
+- feat(graphql-limit-count): rate limit by GraphQL query cost. New 
`complexity` and `node_quantifier` cost strategies with per-field weights 
stored as `graphql_cost_decorations` under a Service; `depth` stays the default 
[#13840](https://github.com/apache/apisix/pull/13840)
+- feat: chaitin-waf response logging through `log_resp`, `resp_body_size` and 
`extra_ignored_content_types`, reported asynchronously after the response has 
been handed back to the client 
[#13763](https://github.com/apache/apisix/pull/13763)
+- feat(ai-proxy-multi): let configured HTTP statuses trigger a fallback via 
`fallback_http_statuses` [#13852](https://github.com/apache/apisix/pull/13852)
+- feat(saml-auth): add the lua-resty-saml 0.2.6 validation options 
`idp_issuers`, `sp_acs_url`, `sp_audiences`, `clock_skew`, `replay_dict` and 
`replay_ttl` [#13964](https://github.com/apache/apisix/pull/13964)
+- fix(redis): send the TLS SNI and add `redis_server_name`, so a Redis behind 
a name-routed TLS front works with `redis_ssl: true`; the SNI is skipped for an 
IP literal host [#13938](https://github.com/apache/apisix/pull/13938)
+- fix(ai-proxy): return 502 when a streaming upstream produces no output, 
instead of falling through to `balancer_by_lua` and answering nothing 
[#13870](https://github.com/apache/apisix/pull/13870)
+- fix(ai-proxy): do not turn a streaming read error after partial output into 
a 5xx, and do not retry a request whose partial output already reached the 
client [#13876](https://github.com/apache/apisix/pull/13876)
+- fix(ai-proxy): avoid aborting streams on empty flushes 
[#13947](https://github.com/apache/apisix/pull/13947)
+- fix(ai-providers): encode the Vertex AI model path segment 
[#13872](https://github.com/apache/apisix/pull/13872)
+- fix(ai-cache): key the passthrough protocol on the client method, path and 
query, so two upstream endpoints no longer collide on one cache entry 
[#13887](https://github.com/apache/apisix/pull/13887)
+- fix(ai-aliyun-content-moderation): report final results without usage 
[#13922](https://github.com/apache/apisix/pull/13922)
+- fix(jwe-decrypt): accept JWE tokens that authenticate the protected header, 
as RFC 7516 requires, and reject an unsupported `alg` or `enc` 
[#13889](https://github.com/apache/apisix/pull/13889)
+- fix(jwe-decrypt): reject malformed tokens with 400 instead of returning 500 
[#13844](https://github.com/apache/apisix/pull/13844)
+- fix(basic-auth): split credentials on the first colon only, so a password 
containing `:` is no longer truncated 
[#13836](https://github.com/apache/apisix/pull/13836)
+- fix(data-mask): keep request header masking effective in the log phase, 
where `set_header()` silently did nothing on a 400 response 
[#13839](https://github.com/apache/apisix/pull/13839)
+- fix(redirect): compare `X-Forwarded-Proto` case-insensitively, so a proxy 
forwarding `HTTPS` no longer triggers an `http_to_https` redirect loop 
[#13865](https://github.com/apache/apisix/pull/13865)
+- fix(ua-restriction): deny the request when any User-Agent header matches the 
`deny_list` [#13869](https://github.com/apache/apisix/pull/13869)
+- fix(traffic-label): cache the compiled match expressions outside the plugin 
config, so the route configuration stays JSON encodable 
[#13901](https://github.com/apache/apisix/pull/13901)
+- fix(aws-lambda): request `/` for a path-less `function_uri` and log function 
error responses [#13908](https://github.com/apache/apisix/pull/13908)
+- fix(ext-plugin-post-resp): set `upstream_addr` and `upstream_response_time` 
for loggers [#13940](https://github.com/apache/apisix/pull/13940)
+- fix(openapi-to-mcp): apply schema defaults before validation, keep the 
resolved `base_url` and headers for the lifetime of an SSE session, and reject 
a document that is not an OpenAPI document 
[#13956](https://github.com/apache/apisix/pull/13956)
