----
-
-#### 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.
-
-#### 1.7.0
-
-* Fixes and improvements
-
-Important changes since 1.6:
-
-* Add [exclude route support](/configuration/inbound/tun) for TUN inbound
-* Add `udp_disable_domain_unmapping` [inbound listen option](/configuration/shared/listen) **1**
-* Add [HTTPUpgrade V2Ray transport](/configuration/shared/v2ray-transport#HTTPUpgrade) support **2**
-* Migrate multiplex and UoT server to inbound **3**
-* Add TCP Brutal support for multiplex **4**
-* Add `wifi_ssid` and `wifi_bssid` route and DNS rules **5**
-* Update quic-go to v0.40.0
-* Update gVisor to 20231113.0
-
-**1**:
-
-If enabled, for UDP proxy requests addressed to a domain,
-the original packet address will be sent in the response instead of the mapped domain.
-
-This option is used for compatibility with clients that
