-## Features
-
-* UDP packet payloads for ordinary UDP proxies and SUDP now use a dedicated binary codec when frpc and frps successfully negotiate the capability under wire protocol v2, using a more compact wire representation. Wire protocol v1 remains JSON; wire protocol v2 falls back to JSON `UDPPacket` when the peer does not support or did not negotiate the capability.
-
 ## Fixes
 
-* Fixed a server panic and remote denial of service caused by a client sending a negative `pool_count`. Negative values are now rejected before work-connection pool resources are allocated.
-* Fixed `frpc verify` ignoring configured `featureGates`, which caused VirtualNet configurations to be rejected even when the feature was enabled.
-* Fixed a case-insensitive validation bypass that allowed `customDomains` under the configured `subDomainHost` to be registered using mixed-case domain names.
+* Fixed a configuration-dependent authentication bypass in `type = "http"` proxies when `routeByHTTPUser` is used together with `httpUser` / `httpPassword`. This affected proxy-style requests. Proxy-style authentication failures now return `407 Proxy Authentication Required`.

-## 3. Pre-release Validation
-
-Run the standard e2e suite locally:
-
-```bash
-make e2e
-```
-
-For releases that touch compatibility-sensitive areas such as login, control
-connections, work connections, visitors, transport, or wire protocol handling,
-also run the manual compatibility e2e suite:
-
-```bash
-make e2e-compatibility
-make e2e-compatibility-floor
-```
-
-`make e2e-compatibility` builds the current `frps` and `frpc`, resolves the
-recent stable release baselines from GitHub, downloads or reuses their binaries,
-and tests current binaries against those historical releases. The default number
-of recent baselines is controlled by `FRP_COMPAT_BASELINE_COUNT` in the
-`Makefile`.
-
-Downloaded release binaries are cached under:
-
-```text
-.cache/e2e-compat/<version>/<os>_<arch>/
-```
-
-For a release validation run that must be exactly reproducible, pass an explicit
-baseline matrix instead of using the floating recent-release list:
-
-```bash
-FRP_COMPAT_BASELINE_VERSIONS="0.X.0 0.Y.0" make e2e-compatibility
-```
-
-Use `make e2e-compatibility-smoke` for a quick single-baseline check while
-iterating locally. If GitHub release metadata requests are rate-limited, set
-`GITHUB_TOKEN` or use `FRP_COMPAT_BASELINE_VERSIONS`.
-
-The compatibility floor is a support-policy decision, not a value that should
-change every release. Update `FRP_COMPAT_FLOOR_VERSION` only when the declared
-compatibility window changes.

-# Deprecations
-
-This document tracks deprecated features and APIs that are still shipped but scheduled for removal. Maintainers should review this list before each release to decide whether any items are due for removal.
-
-For the version compatibility policy that bounds these support windows, see the latest `Release.md`.
-
-## Active
-
-### Wire protocol v1
-
-- **Deprecated since:** v0.70.0 (planned, when v2 becomes the default).
-- **Removal target:** v0.78.0 or later. v0.69.0 (the last release where v1 is the default) is supported until v0.78.0 is released, so v0.77.0 is the last release that must keep v1 support.
-- **Replacement:** wire protocol v2 (`transport.wireProtocol = "v2"` in frpc).
-- **Code references:** v1 message types and codec under `pkg/msg/` and the protocol negotiation path in `client/` and `server/`.
-- **Notes:** Removing v1 will also drop compatibility with any frpc/frps that does not negotiate v2.
-
-### INI configuration format
-
-- **Deprecated since:** predates this document; startup warning has been in place for several releases.
-- **Removal target:** TBD.
-- **Replacement:** YAML / JSON / TOML.
-- **Code references:**
-  - `cmd/frpc/sub/root.go` — frpc startup warning.
-  - `cmd/frps/root.go` — frps startup warning.
-  - `pkg/config/legacy/` — legacy INI parser; remove together with the warnings.
-
-### Visitor connections without `runID`
-
-- **Deprecated since:** v0.50.0 (when `runID` was introduced).
-- **Removal target:** TBD.
-- **Replacement:** require `runID` on every visitor connection.
-- **Code references:**
-  - `server/service.go` — `RegisterVisitorConn` still accepts empty `runID` for backward compatibility.
-- **Notes:** Removal will break frpc clients released before v0.50.0. Schedule for a release where dropping pre-v0.50.0 frpc is acceptable.
