#### 1.11.0-alpha.15

* Improve multi network dialing **1**
* Fixes and improvements

**1**:

New options allow you to configure the network strategy flexibly.

See [Dial Fields](/configuration/shared/dial/#network_strategy),
[Rule Action](/configuration/route/rule_action/#network_strategy)
and [Route](/configuration/route/#default_network_strategy).

#### 1.11.0-alpha.14

* Add multi network dialing **1**
* Fixes and improvements

**1**:

Similar to Surge's strategy.

New options allow you to connect using multiple network interfaces,
prefer or only use one type of interface,
and configure a timeout to fallback to other interfaces.

See [Dial Fields](/configuration/shared/dial/#network_strategy),
[Rule Action](/configuration/route/rule_action/#network_strategy)
and [Route](/configuration/route/#default_network_strategy).

#### 1.11.0-alpha.13

* Fixes and improvements

#### 1.11.0-alpha.12

* Merge route options to route actions **1**
* Add `network_type`, `network_is_expensive` and `network_is_constrainted` rule items **2**
* Fixes and improvements

**1**:

Route options in DNS route actions will no longer be considered deprecated,
see [DNS Route Action](/configuration/dns/rule_action/).

Also, now `udp_disable_domain_unmapping` and `udp_connect` can also be configured in route action,
see [Route Action](/configuration/route/rule_action/).

**2**:

When using in graphical clients, new routing rule items allow you to match on
network type (WIFI, cellular, etc.), whether the network is expensive, and whether Low Data Mode is enabled.

See [Route Rule](/configuration/route/rule/), [DNS Route Rule](/configuration/dns/rule/)
and [Headless Rule](/configuration/rule-set/headless-rule/).

#### 1.11.0-alpha.9

* Improve tun compatibility **1**
* Fixes and improvements

**1**:

When `gvisor` tun stack is enabled, even if the request passes routing,
if the outbound connection establishment fails,
the connection still does not need to be established and a TCP RST is replied.

#### 1.11.0-alpha.7

* Introducing rule actions **1**

**1**:

New rule actions replace legacy inbound fields and special outbound fields,
and can be used for pre-matching **2**.

See [Rule](/configuration/route/rule/),
[Rule Action](/configuration/route/rule_action/),
[DNS Rule](/configuration/dns/rule/) and
[DNS Rule Action](/configuration/dns/rule_action/).

For migration, see
[Migrate legacy special outbounds to rule actions](/migration/#migrate-legacy-special-outbounds-to-rule-actions),
[Migrate legacy inbound fields to rule actions](/migration/#migrate-legacy-inbound-fields-to-rule-actions)
and [Migrate legacy DNS route options to rule actions](/migration/#migrate-legacy-dns-route-options-to-rule-actions).

**2**:

Similar to Surge's pre-matching.

Specifically, new rule actions allow you to reject connections with
TCP RST (for TCP connections) and ICMP port unreachable (for UDP packets)
before connection established to improve tun's compatibility.

See [Rule Action](/configuration/route/rule_action/).

#### 1.11.0-alpha.6

### 1.10.1

* Fixes and improvements

### 1.10.0

Important changes since 1.9:

* Introducing auto-redirect **1**
* Add AdGuard DNS Filter support **2**
* TUN address fields are merged **3**
* Add custom options for `auto-route` and `auto-redirect` **4**
* Drop support for go1.18 and go1.19 **5**
* Add tailing comma support in JSON configuration
* Improve sniffers **6**
* Add new `inline` rule-set type **7**
* Add access control options for Clash API **8**
* Add `rule_set_ip_cidr_accept_empty` DNS address filter rule item **9**
* Add auto reload support for local rule-set
* Update fsnotify usages **10**

* Add `rule-set decompile` command
* Add `process_path_regex` rule item
* Update uTLS to v1.6.7 **11**
* Optimize memory usages of rule-sets **12**

**1**:

The new auto-redirect feature allows TUN to automatically
configure connection redirection to improve proxy performance.

When auto-redirect is enabled, new route address set options will allow you to
automatically configure destination IP CIDR rules from a specified rule set to the firewall.

Specified or unspecified destinations will bypass the sing-box routes to get better performance
(for example, keep hardware offloading of direct traffics on the router).

See [TUN](/configuration/inbound/tun).

**2**:

The new feature allows you to use AdGuard DNS Filter lists in a sing-box without AdGuard Home.

See [AdGuard DNS Filter](/configuration/rule-set/adguard/).

**3**:

See [Migration](/migration/#tun-address-fields-are-merged).

**4**:

See [iproute2_table_index](/configuration/inbound/tun/#iproute2_table_index),
[iproute2_rule_index](/configuration/inbound/tun/#iproute2_rule_index),
[auto_redirect_input_mark](/configuration/inbound/tun/#auto_redirect_input_mark) and
[auto_redirect_output_mark](/configuration/inbound/tun/#auto_redirect_output_mark).

**5**:

Due to maintenance difficulties, sing-box 1.10.0 requires at least Go 1.20 to compile.

**6**:

BitTorrent, DTLS, RDP, SSH sniffers are added.

Now the QUIC sniffer can correctly extract the server name from Chromium requests and
can identify common QUIC clients, including
Chromium, Safari, Firefox, quic-go (including uquic disguised as Chrome).

**7**:

The new [rule-set](/configuration/rule-set/) type inline (which also becomes the default type)
allows you to write headless rules directly without creating a rule-set file.

**8**:

With new access control options, not only can you allow Clash dashboards
to access the Clash API on your local network,
you can also manually limit the websites that can access the API instead of allowing everyone.

See [Clash API](/configuration/experimental/clash-api/).

**9**:

See [DNS Rule](/configuration/dns/rule/#rule_set_ip_cidr_accept_empty).

**10**:

sing-box now uses fsnotify correctly and will not cancel watching
if the target file is deleted or recreated via rename (e.g. `mv`).

This affects all path options that support reload, including
`tls.certificate_path`, `tls.key_path`, `tls.ech.key_path` and `rule_set.path`.

**11**:

Some legacy chrome fingerprints have been removed and will fallback to chrome,
see [utls](/configuration/shared/tls#utls).

**12**:

See [Source Format](/configuration/rule-set/source-format/#version).

* Fixes and improvements

Important changes since 1.7:

* Migrate cache file from Clash API to independent options **1**
* Introducing [rule-set](/configuration/rule-set/) **2**
* Add `sing-box geoip`, `sing-box geosite` and `sing-box rule-set` commands **3**

* Add `idle_timeout` for URLTest outbound **9**
* Add simple loopback detect
* Optimize memory usage of idle connections
* Update uTLS to 1.5.4 **10**
* Update dependencies **11**

**1**:

See [Cache File](/configuration/experimental/cache-file/) and
[Migration](/migration/#migrate-cache-file-from-clash-api-to-independent-options).

**2**:

rule-set is independent collections of rules that can be compiled into binaries to improve performance.
Compared to legacy GeoIP and Geosite resources,
it can include more types of rules, load faster,
use less memory, and update automatically.

See [Route#rule_set](/configuration/route/#rule_set),
[Route Rule](/configuration/route/rule/),
[DNS Rule](/configuration/dns/rule/),
[rule-set](/configuration/rule-set/),
[Source Format](/configuration/rule-set/source-format/) and
[Headless Rule](/configuration/rule-set/headless-rule/).

For GEO resources migration, see [Migrate GeoIP to rule-sets](/migration/#migrate-geoip-to-rule-sets) and
[Migrate Geosite to rule-sets](/migration/#migrate-geosite-to-rule-sets).

**3**:

New commands manage GeoIP, Geosite and rule-set resources, and help you migrate GEO resources to rule-sets.

**4**:

Logical rules in route rules, DNS rules, and the new headless rule now allow nesting of logical rules.

**5**:

The `private` GeoIP country never existed and was actually implemented inside V2Ray.
Since GeoIP was deprecated, we made this rule independent, see [Migration](/migration/#migrate-geoip-to-rule-sets).

**6**:

JSON parse errors will now include the current key path.
Only takes effect when compiled with Go 1.21+.

**7**:

All internal DNS queries now skip DNS rules with `server` type `fakeip`,
and the default DNS server can no longer be `fakeip`.

This change is intended to break incorrect usage and essentially requires no action.

**8**:

See [TUN](/configuration/inbound/tun/) inbound and [WireGuard](/configuration/outbound/wireguard/) outbound.

**9**:

When URLTest is idle for a certain period of time, the scheduled delay test will be paused.

**10**:

Added some new [fingerprints](/configuration/shared/tls#utls).
Also, starting with this release, uTLS requires at least Go 1.20.

**11**:

Updated `cloudflare-tls`, `gomobile`, `smux`, `tfo-go` and `wireguard-go` to latest, `quic-go` to `0.40.1` and  `gvisor`
to `20231204.0`

#### 1.8.0-alpha.13

* Fixes and improvements

#### 1.8.0-alpha.10

* Add `idle_timeout` for URLTest outbound **1**
* Fixes and improvements

**1**:

When URLTest is idle for a certain period of time, the scheduled delay test will be paused.

#### 1.7.2

* Fixes and improvements

#### 1.8.0-alpha.8

* Add context to JSON decode error message **1**
* Reject internal fake-ip queries **2**
* Fixes and improvements

**1**:

JSON parse errors will now include the current key path.
Only takes effect when compiled with Go 1.21+.

**2**:

All internal DNS queries now skip DNS rules with `server` type `fakeip`,
and the default DNS server can no longer be `fakeip`.

This change is intended to break incorrect usage and essentially requires no action.

#### 1.8.0-alpha.7

* Fixes and improvements

#### 1.7.1

* Fixes and improvements

#### 1.8.0-alpha.6

* Fix rule-set matching logic **1**
* Fixes and improvements

**1**:

Now the rules in the `rule_set` rule item can be logically considered to be merged into the rule using rule-sets,
rather than completely following the AND logic.

#### 1.8.0-alpha.5

* Parallel rule-set initialization
* Independent `source_ip_is_private` and `ip_is_private` rules **1**

**1**:

The `private` GeoIP country never existed and was actually implemented inside V2Ray.
Since GeoIP was deprecated, we made this rule independent, see [Migration](/migration/#migrate-geoip-to-rule-sets).

#### 1.8.0-alpha.1

* Migrate cache file from Clash API to independent options **1**
* Introducing [rule-set](/configuration/rule-set/) **2**
* Add `sing-box geoip`, `sing-box geosite` and `sing-box rule-set` commands **3**
* Allow nested logical rules **4**

**1**:

See [Cache File](/configuration/experimental/cache-file/) and
[Migration](/migration/#migrate-cache-file-from-clash-api-to-independent-options).

**2**:

rule-set is independent collections of rules that can be compiled into binaries to improve performance.
Compared to legacy GeoIP and Geosite resources,
it can include more types of rules, load faster,
use less memory, and update automatically.

See [Route#rule_set](/configuration/route/#rule_set),
[Route Rule](/configuration/route/rule/),
[DNS Rule](/configuration/dns/rule/),
[rule-set](/configuration/rule-set/),
[Source Format](/configuration/rule-set/source-format/) and
[Headless Rule](/configuration/rule-set/headless-rule/).

For GEO resources migration, see [Migrate GeoIP to rule-sets](/migration/#migrate-geoip-to-rule-sets) and
[Migrate Geosite to rule-sets](/migration/#migrate-geosite-to-rule-sets).

**3**:

New commands manage GeoIP, Geosite and rule-set resources, and help you migrate GEO resources to rule-sets.

**4**:

Logical rules in route rules, DNS rules, and the new headless rule now allow nesting of logical rules.

See [TUIC inbound](/configuration/inbound/tuic/)
and [TUIC outbound](/configuration/outbound/tuic/)

**2**:

This is the TUIC port of the [UDP over TCP protocol](/configuration/shared/udp-over-tcp/), designed to provide a QUIC
stream based UDP relay mode that TUIC does not provide. Since it is an add-on protocol, you will need to use sing-box or
another program compatible with the protocol as a server.

This mode has no positive effect in a proper UDP proxy scenario and should only be applied to relay streaming UDP
traffic (basically QUIC streams).
