* 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**

* 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-rc.11

* Update uTLS to 1.5.4 **2**
* Update dependencies **3**
* Fixes and improvements

**1**:

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

**2**:

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

**3**:

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

This may break something, good luck!

#### 1.7.4

by the Apple App Store, so updates to Apple Platforms will be delayed._

**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).

*3*:

Requires sing-box to be compiled with Go 1.21.
