 ## [Unreleased]
 
-### Changed
-
-- `default_local_cidr_any` now defaults to false, meaning that any firewall rule
-  intended to target an `unsafe_routes` entry must explicitly declare it via the
-  `local_cidr` field. This is almost always the intended behavior. This flag is
-  deprecated and will be removed in a future release.
-
-## [1.9.4] - 2024-09-09
-
-### Added
-
-- Support UDP dialing with gVisor. (#1181)
-
-### Changed
-
-- Make some Nebula state programmatically available via control object. (#1188)
-- Switch internal representation of IPs to netip, to prepare for IPv6 support
-  in the overlay. (#1173)
-- Minor build and cleanup changes. (#1171, #1164, #1162)
-- Various dependency updates. (#1195, #1190, #1174, #1168, #1167, #1161, #1147, #1146)
-
-### Fixed
-
-- Fix a bug on big endian hosts, like mips. (#1194)
-- Fix a rare panic if a local index collision happens. (#1191)
-- Fix integer wraparound in the calculation of handshake timeouts on 32-bit targets. (#1185)
-
-## [1.9.3] - 2024-06-06
-
-### Fixed
-
-- Initialize messageCounter to 2 instead of verifying later. (#1156)
-
-## [1.9.2] - 2024-06-03
-
-### Fixed
-
-- Ensure messageCounter is set before handshake is complete. (#1154)
-
-## [1.9.1] - 2024-05-29
-
-### Fixed
-
-- Fixed a potential deadlock in GetOrHandshake. (#1151)
-
-## [1.9.0] - 2024-05-07
-
-### Deprecated
-
-- This release adds a new setting `default_local_cidr_any` that defaults to
-  true to match previous behavior, but will default to false in the next
-  release (1.10). When set to false, `local_cidr` is matched correctly for
-  firewall rules on hosts acting as unsafe routers, and should be set for any
-  firewall rules you want to allow unsafe route hosts to access. See the issue
-  and example config for more details. (#1071, #1099)
-
-### Added
-
-- Nebula now has an official Docker image `nebulaoss/nebula` that is
-  distroless and contains just the `nebula` and `nebula-cert` binaries. You
-  can find it here: https://hub.docker.com/r/nebulaoss/nebula (#1037)
-
-- Experimental binaries for `loong64` are now provided. (#1003)
-
-- Added example service script for OpenRC. (#711)
-
-- The SSH daemon now supports inlined host keys. (#1054)
-
-- The SSH daemon now supports certificates with `sshd.trusted_cas`. (#1098)
-
-### Changed
-
-- Config setting `tun.unsafe_routes` is now reloadable. (#1083)
-
-- Small documentation and internal improvements. (#1065, #1067, #1069, #1108,
-  #1109, #1111, #1135)
-
-- Various dependency updates. (#1139, #1138, #1134, #1133, #1126, #1123, #1110,
-  #1094, #1092, #1087, #1086, #1085, #1072, #1063, #1059, #1055, #1053, #1047,
-  #1046, #1034, #1022)
-
-### Removed
-
-- Support for the deprecated `local_range` option has been removed. Please
-  change to `preferred_ranges` (which is also now reloadable). (#1043)
-
-- We are now building with go1.22, which means that for Windows you need at
-  least Windows 10 or Windows Server 2016. This is because support for earlier
-  versions was removed in Go 1.21. See https://go.dev/doc/go1.21#windows (#981)
-
-- Removed vagrant example, as it was unmaintained. (#1129)
-
-- Removed Fedora and Arch nebula.service files, as they are maintained in the
-  upstream repos. (#1128, #1132)
-
-- Remove the TCP round trip tracking metrics, as they never had correct data
-  and were an experiment to begin with. (#1114)
-
-### Fixed
-
-- Fixed a potential deadlock introduced in 1.8.1. (#1112)
-
-- Fixed support for Linux when IPv6 has been disabled at the OS level. (#787)
-
-- DNS will return NXDOMAIN now when there are no results. (#845)
-
-- Allow `::` in `lighthouse.dns.host`. (#1115)
-
-- Capitalization of `NotAfter` fixed in DNS TXT response. (#1127)
-
-- Don't log invalid certificates. It is untrusted data and can cause a large
-  volume of logs. (#1116)
-
-## [1.8.2] - 2024-01-08
-
-### Fixed
-
-- Fix multiple routines when listen.port is zero. This was a regression
-  introduced in v1.6.0. (#1057)
-
-### Changed
-
-- Small dependency update for Noise. (#1038)
-
-## [1.8.1] - 2023-12-19
-
-### Security
-
-- Update `golang.org/x/crypto`, which includes a fix for CVE-2023-48795. (#1048)
-
-### Fixed
-
-- Fix a deadlock introduced in v1.8.0 that could occur during handshakes. (#1044)
-
-- Fix mobile builds. (#1035)
-
-## [1.8.0] - 2023-12-06
-
-### Deprecated
-
-- The next minor release of Nebula, 1.9.0, will require at least Windows 10 or
-  Windows Server 2016. This is because support for earlier versions was removed
-  in Go 1.21. See https://go.dev/doc/go1.21#windows
-
-### Added
-
-- Linux: Notify systemd of service readiness. This should resolve timing issues
-  with services that depend on Nebula being active. For an example of how to
-  enable this, see: `examples/service_scripts/nebula.service`. (#929)
-
-- Windows: Use Registered IO (RIO) when possible. Testing on a Windows 11
-  machine shows ~50x improvement in throughput. (#905)
-
-- NetBSD, OpenBSD: Added rudimentary support. (#916, #812)
-
-- FreeBSD: Add support for naming tun devices. (#903)
-
-### Changed
-
-- `pki.disconnect_invalid` will now default to true. This means that once a
-  certificate expires, the tunnel will be disconnected. If you use SIGHUP to
-  reload certificates without restarting Nebula, you should ensure all of your
-  clients are on 1.7.0 or newer before you enable this feature. (#859)
-
-- Limit how often a busy tunnel can requery the lighthouse. The new config
-  option `timers.requery_wait_duration` defaults to `60s`. (#940)
-
-- The internal structures for hostmaps were refactored to reduce memory usage
-  and the potential for subtle bugs. (#843, #938, #953, #954, #955)
-
-- Lots of dependency updates.
-
-### Fixed
-
-- Windows: Retry wintun device creation if it fails the first time. (#985)
-
-- Fix issues with firewall reject packets that could cause panics. (#957)
-
-- Fix relay migration during re-handshakes. (#964)
-
-- Various other refactors and fixes. (#935, #952, #972, #961, #996, #1002,
-  #987, #1004, #1030, #1032, ...)
-
-## [1.7.2] - 2023-06-01
-
-### Fixed
-
-- Fix a freeze during config reload if the `static_host_map` config was changed. (#886)
-
-## [1.7.1] - 2023-05-18
-
-### Fixed
-
-- Fix IPv4 addresses returned by `static_host_map` DNS lookup queries being
-  treated as IPv6 addresses. (#877)
-
-## [1.7.0] - 2023-05-17
-
-### Added
-
-- `nebula-cert ca` now supports encrypting the CA's private key with a
-  passphrase. Pass `-encrypt` in order to be prompted for a passphrase.
-  Encryption is performed using AES-256-GCM and Argon2id for KDF. KDF
-  parameters default to RFC recommendations, but can be overridden via CLI
-  flags `-argon-memory`, `-argon-parallelism`, and `-argon-iterations`. (#386)
-
-- Support for curve P256 and BoringCrypto has been added. See README section
-  "Curve P256 and BoringCrypto" for more details. (#865, #861, #769, #856, #803)
-
-- New firewall rule `local_cidr`. This could be used to filter destinations
-  when using `unsafe_routes`. (#507)
-
-- Add `unsafe_route` option `install`. This controls whether the route is
-  installed in the systems routing table. (#831)
-
-- Add `tun.use_system_route_table` option. Set to true to manage unsafe routes
-  directly on the system route table with gateway routes instead of in Nebula
-  configuration files. This is only supported on Linux. (#839)
-
-- The metric `certificate.ttl_seconds` is now exposed via stats. (#782)
-
-- Add `punchy.respond_delay` option. This allows you to change the delay
-  before attempting punchy.respond. Default is 5 seconds. (#721)
-
-- Added SSH commands to allow the capture of a mutex profile. (#737)
-
-- You can now set `lighthouse.calculated_remotes` to make it possible to do
-  handshakes without a lighthouse in certain configurations. (#759)
-
-- The firewall can be configured to send REJECT replies instead of the default
-  DROP behavior. (#738)
-
-- For macOS, an example launchd configuration file is now provided. (#762)
-
-### Changed
-
-- Lighthouses and other `static_host_map` entries that use DNS names will now
-  be automatically refreshed to detect when the IP address changes. (#796)
-
-- Lighthouses send ACK replies back to clients so that they do not fall into
-  connection testing as often by clients. (#851, #408)
-
-- Allow the `listen.host` option to contain a hostname. (#825)
-
-- When Nebula switches to a new certificate (such as via SIGHUP), we now
-  rehandshake with all existing tunnels. This allows firewall groups to be
-  updated and `pki.disconnect_invalid` to know about the new certificate
-  expiration time. (#838, #857, #842, #840, #835, #828, #820, #807)
-
-### Fixed
-
-- Always disconnect blocklisted hosts, even if `pki.disconnect_invalid` is
-  not set. (#858)
-
-- Dependencies updated and go1.20 required. (#780, #824, #855, #854)
-
-- Fix possible race condition with relays. (#827)
-
-- FreeBSD: Fix connection to the localhost's own Nebula IP. (#808)
-
-- Normalize and document some common log field values. (#837, #811)
-
-- Fix crash if you set unlucky values for the firewall timeout configuration
-  options. (#802)
-
-- Make DNS queries case insensitive. (#793)
-
-- Update example systemd configurations to want `nss-lookup`. (#791)
-
-- Errors with SSH commands now go to the SSH tunnel instead of stderr. (#757)
-
-- Fix a hang when shutting down Android. (#772)
-
-## [1.6.1] - 2022-09-26
-
-### Fixed
-
-- Refuse to process underlay packets received from overlay IPs. This prevents
-  confusion on hosts that have unsafe routes configured. (#741)
-
-- The ssh `reload` command did not work on Windows, since it relied on sending
-  a SIGHUP signal internally. This has been fixed. (#725)
-
-- A regression in v1.5.2 that broke unsafe routes on Mobile clients has been
-  fixed. (#729)
-
-## [1.6.0] - 2022-06-30
-
-### Added
-
-- Experimental: nebula clients can be configured to act as relays for other nebula clients.
-  Primarily useful when stubborn NATs make a direct tunnel impossible. (#678)
-
-- Configuration option to report manually specified `ip:port`s to lighthouses. (#650)
-
-- Windows arm64 build. (#638)
-
-- `punchy` and most `lighthouse` config options now support hot reloading. (#649)
-
-### Changed
-
-- Build against go 1.18. (#656)
-
-- Promoted `routines` config from experimental to supported feature. (#702)
-
-- Dependencies updated. (#664)
-
-### Fixed
-
-- Packets destined for the same host that sent it will be returned on MacOS.
-  This matches the default behavior of other operating systems. (#501)
-
-- `unsafe_route` configuration will no longer crash on Windows. (#648)
-
-- A few panics that were introduced in 1.5.x. (#657, #658, #675)
-
-### Security
-
-- You can set `listen.send_recv_error` to control the conditions in which
-  `recv_error` messages are sent. Sending these messages can expose the fact
-  that Nebula is running on a host, but it speeds up re-handshaking. (#670)
-
-### Removed
-
-- `x509` config stanza support has been removed. (#685)
-
-## [1.5.2] - 2021-12-14
-
-### Added
-
-- Warn when a non lighthouse node does not have lighthouse hosts configured. (#587)
-

-- No longer fatals if expired CA certificates are present in `pki.ca`, as long as 1 valid CA is present. (#599)
-
-- `nebula-cert` will now enforce ipv4 addresses. (#604)
-
-- Warn on macOS if an unsafe route cannot be created due to a collision with an
-  existing route. (#610)
-
-- Warn if you set a route MTU on platforms where we don't support it. (#611)
-
-### Fixed
-
-- Rare race condition when tearing down a tunnel due to `recv_error` and sending packets on another thread. (#590)
-
-- Bug in `routes` and `unsafe_routes` handling that was introduced in 1.5.0. (#595)
-
-- `-test` mode no longer results in a crash. (#602)
-
-### Removed
-
-- `x509.ca` config alias for `pki.ca`. (#604)
-
-### Security
-
-- Upgraded `golang.org/x/crypto` to address an issue which allowed unauthenticated clients to cause a panic in SSH
-  servers. (#603)

-### Logging conventions
-
-A log message (the string/format passed to `Info`, `Error`, `Debug` etc, as well as their `Sprintf` counterparts) should
-be a descriptive message about the event and may contain specific identifying characteristics. Regardless of the
-level of detail in the message identifying characteristics should always be included via `WithField`, `WithFields` or
-`WithError`
-
-If an error is being logged use `l.WithError(err)` so that there is better discoverability about the event as well
-as the specific error condition.
-
-#### Common fields
-
-- `cert` - a `cert.NebulaCertificate` object, do not `.String()` this manually, `logrus` will marshal objects properly
-  for the formatter it is using.
-- `fingerprint` - a single `NebeulaCertificate` hex encoded fingerprint
-- `fingerprints` - an array of `NebulaCertificate` hex encoded fingerprints
-- `fwPacket` - a FirewallPacket object
-- `handshake` - an object containing:
-    - `stage` - the current stage counter
-    - `style` - noise handshake style `ix_psk0`, `xx`, etc
-- `header` - a nebula header object
-- `udpAddr` - a `net.UDPAddr` object
-- `udpIp` - a udp ip address
-- `vpnIp` - vpn ip of the host (remote or local)
-- `relay` - the vpnIp of the relay host that is or should be handling the relay packet
-- `relayFrom` - The vpnIp of the initial sender of the relayed packet 
-- `relayTo` - The vpnIp of the final destination of a relayed packet
-
-#### Example:
-
-```
-l.WithError(err).
-    WithField("vpnIp", IntIp(hostinfo.hostId)).
-    WithField("udpAddr", addr).
-    WithField("handshake", m{"stage": 1, "style": "ix"}).
-    Info("Invalid certificate from host")

-## Curve P256 and BoringCrypto
-
-The default curve used for cryptographic handshakes and signatures is Curve25519. This is the recommended setting for most users. If your deployment has certain compliance requirements, you have the option of creating your CA using `nebula-cert ca -curve P256` to use NIST Curve P256. The CA will then sign certificates using ECDSA P256, and any hosts using these certificates will use P256 for ECDH handshakes.
-
-In addition, Nebula can be built using the [BoringCrypto GOEXPERIMENT](https://github.com/golang/go/blob/go1.20/src/crypto/internal/boring/README.md) by running either of the following make targets:
-
-    make bin-boringcrypto
-    make release-boringcrypto
-
-This is not the recommended default deployment, but may be useful based on your compliance requirements.

-## v1
+### Compiling the protobuf definition
 
-This version is deprecated.
-
-A `protobuf` definition of the certificate format is included at `cert_v1.proto`
-
-To compile the definition you will need `protoc` installed.
+Make sure you have `protoc` installed.
 
 To compile for `go` with the same version of protobuf specified in go.mod:
 
 ```bash
-make proto
+make
 ```
-
-## v2
-
-This is the latest version which uses asn.1 DER encoding. It can support ipv4 and ipv6 and tolerate
-future certificate changes better than v1.
-
-`cert_v2.asn1` defines the wire format and can be used to compile marshalers.

-# [Wintun Network Adapter](https://www.wintun.net/)
-### TUN Device Driver for Windows
-
-This is a layer 3 TUN driver for Windows 7, 8, 8.1, and 10. Originally created for [WireGuard](https://www.wireguard.com/), it is intended to be useful to a wide variety of projects that require layer 3 tunneling devices with implementations primarily in userspace.
-
-## Installation
-
-Wintun is deployed as a platform-specific `wintun.dll` file. Install the `wintun.dll` file side-by-side with your application. Download the dll from [wintun.net](https://www.wintun.net/), alongside the header file for your application described below.
-
-## Usage
-
-Include the [`wintun.h` file](https://git.zx2c4.com/wintun/tree/api/wintun.h) in your project simply by copying it there and dynamically load the `wintun.dll` using [`LoadLibraryEx()`](https://docs.microsoft.com/en-us/windows/win32/api/libloaderapi/nf-libloaderapi-loadlibraryexa) and [`GetProcAddress()`](https://docs.microsoft.com/en-us/windows/win32/api/libloaderapi/nf-libloaderapi-getprocaddress) to resolve each function, using the typedefs provided in the header file. The [`InitializeWintun` function in the example.c code](https://git.zx2c4.com/wintun/tree/example/example.c) provides this in a function that you can simply copy and paste.
-
-With the library setup, Wintun can then be used by first creating an adapter, configuring it, and then setting its status to "up". Adapters have names (e.g. "OfficeNet") and types (e.g. "Wintun").
-
-```C
-WINTUN_ADAPTER_HANDLE Adapter1 = WintunCreateAdapter(L"OfficeNet", L"Wintun", &SomeFixedGUID1);
-WINTUN_ADAPTER_HANDLE Adapter2 = WintunCreateAdapter(L"HomeNet", L"Wintun", &SomeFixedGUID2);
-WINTUN_ADAPTER_HANDLE Adapter3 = WintunCreateAdapter(L"Data Center", L"Wintun", &SomeFixedGUID3);
-```
-
-After creating an adapter, we can use it by starting a session:
-
-```C
-WINTUN_SESSION_HANDLE Session = WintunStartSession(Adapter2, 0x400000);
-```
-
-Then, the `WintunAllocateSendPacket` and `WintunSendPacket` functions can be used for sending packets ([used by `SendPackets` in the example.c code](https://git.zx2c4.com/wintun/tree/example/example.c)):
-
-```C
-BYTE *OutgoingPacket = WintunAllocateSendPacket(Session, PacketDataSize);
-if (OutgoingPacket)
-{
-    memcpy(OutgoingPacket, PacketData, PacketDataSize);
-    WintunSendPacket(Session, OutgoingPacket);
-}
-else if (GetLastError() != ERROR_BUFFER_OVERFLOW) // Silently drop packets if the ring is full
-    Log(L"Packet write failed");
-```
-
-And the `WintunReceivePacket` and `WintunReleaseReceivePacket` functions can be used for receiving packets ([used by `ReceivePackets` in the example.c code](https://git.zx2c4.com/wintun/tree/example/example.c)):
-
-```C
-for (;;)
-{
-    DWORD IncomingPacketSize;
-    BYTE *IncomingPacket = WintunReceivePacket(Session, &IncomingPacketSize);
-    if (IncomingPacket)
-    {
-        DoSomethingWithPacket(IncomingPacket, IncomingPacketSize);
-        WintunReleaseReceivePacket(Session, IncomingPacket);
-    }
-    else if (GetLastError() == ERROR_NO_MORE_ITEMS)
-        WaitForSingleObject(WintunGetReadWaitEvent(Session), INFINITE);
-    else
-    {
-        Log(L"Packet read failed");
-        break;
-    }
-}
-```
-
-Some high performance use cases may want to spin on `WintunReceivePackets` for a number of cycles before falling back to waiting on the read-wait event.
-
-You are **highly encouraged** to read the [**example.c short example**](https://git.zx2c4.com/wintun/tree/example/example.c) to see how to put together a simple userspace network tunnel.

-
-#### WintunCreateAdapter()
-
-`WINTUN_ADAPTER_HANDLE WintunCreateAdapter (const WCHAR * Name, const WCHAR * TunnelType, const GUID * RequestedGUID)`

Possible errors include the following: ERROR\_HANDLE\_EOF Wintun adapter is terminating; ERROR\_BUFFER\_OVERFLOW Wintun buffer is full;
-
-#### WintunSendPacket()
-
-`void WintunSendPacket (WINTUN_SESSION_HANDLE Session, const BYTE * Packet)`
-
-Sends the packet and releases internal buffer. WintunSendPacket is thread-safe, but the WintunAllocateSendPacket order of calls define the packet sending order. This means the packet is not guaranteed to be sent in the WintunSendPacket yet.
-
-**Parameters**
-
-- *Session*: Wintun session handle obtained with WintunStartSession
-- *Packet*: Packet obtained with WintunAllocateSendPacket

-## Building
-
-**Do not distribute drivers or files named "Wintun", as they will most certainly clash with official deployments. Instead distribute [`wintun.dll` as downloaded from wintun.net](https://www.wintun.net).**
-
-General requirements:
-
-- [Visual Studio 2019](https://visualstudio.microsoft.com/downloads/) with Windows SDK
-- [Windows Driver Kit](https://docs.microsoft.com/en-us/windows-hardware/drivers/download-the-wdk)
-
-`wintun.sln` may be opened in Visual Studio for development and building. Be sure to run `bcdedit /set testsigning on` and then reboot before to enable unsigned driver loading. The default run sequence (F5) in Visual Studio will build the example project and its dependencies.
