+
+## Linux版本
+
+linux shell脚本，自动化筛选
+
+具体使用流程，需要编译里面 fping 4.2 修改版本，另外需要系统安装curl支持。
+
+下载修改过的源码 fping-4.2.tar.gz  点击下载[Linux源码](https://proxy.freecdn.workers.dev/?url=https://github.com/badafans/better-cloudflare-ip/releases/latest/download/linux.tar.gz)
+
+具体编译使用流程如下
+
+ ```bash
+curl https://github.com/badafans/better-cloudflare-ip/releases/latest/download/linux.tar.gz -o linux.tar.gz
+
+tar -vxf linux.tar.gz
+
+cd linux
+
+./configure
+
+make
+
+cd src
+
+sudo ./cf.sh
+```
+
+1.根据你当前带宽设置一个期望的CF速度的大小，比如说家里宽带100兆，如果想要CF单线程下载速度达到20兆的宽带效果，直接输入数值 20 并按回车键
+
+2.等待程序全自动测试结束，找到符合条件的 IP 会在控制台窗口里面输出结果
+
+3.如果你当前网络环境非常差，建议调低期望的带宽值，不然程序会一直停留在查找筛选的过程中
+
+4.外置的 anycast ip 数量根据现有可用路由动态调整，每次测试提取其中的1280分之1，运气好的话五十多秒钟就能获取到自己想要的优选 IP
+
+## Windows版本
+
+windows批处理全自动无门槛操作，自动化筛选
+
+fping-4.2 for win32 修改版（基于 msys2.0 修改编译）点击下载[Windows版本](https://proxy.freecdn.workers.dev/?url=https://github.com/badafans/better-cloudflare-ip/releases/latest/download/windows.zip)
+
+1.解压后运行 CF优选IP.bat 批处理文件（可能需要管理员权限运行，对于 Windows 7 用户或者 cmd 命令行里面不支持curl命令的，需要先解压curl.exe到当前目录）
+
+2.根据你当前带宽设置一个期望的CF速度的大小，比如说家里宽带100兆，如果想要CF单线程下载速度达到20兆的宽带效果，直接输入数值 20 并按回车键
+
+3.等待程序全自动测试结束，找到符合条件的 IP 会在控制台窗口里面输出结果（可以结合里面的单IP测速的批处理来做校验测试）
+
+4.如果你当前网络环境非常差，建议调低期望的带宽值，不然程序会一直停留在查找筛选的过程中
+
+5.外置的 anycast ip 数量根据现有可用路由动态调整，每次测试提取其中的1280分之1，运气好的话一分多钟就能获取到自己想要的优选 IP
+
+## Android版本
+
+1.安装termux，完整复制下方链接粘贴到termux并回车
+
+``` bash
+curl https://proxy.freecdn.workers.dev/?url=https://raw.githubusercontent.com/badafans/better-cloudflare-ip/master/shell/cf.sh -o cf.sh && chmod +x cf.sh && ./cf.sh
+```

+
+6.由于Android termux本身难以支持root权限，整套ICMP丢包测试逻辑完全重新架构，不依赖与fping，所以整体测试相对较为耗时

+fping 4.2 (2019-02-19)
+======================
+
+## New features
+
+- New option -x / --reachable to check if the number of reachable hosts is >= a certain
+  number. Useful for example to implement connectivity-checks (#138, thanks @deepak0004)
+
+## Bugfixes and other changes
+
+- Allow decimal numbers for '-t', '-i', '-p', and '-Q'
+- Fix build with --disable-ipv6 (#134, thanks @Polynomial-C)
+- Fix hang with '-6', with ipv6 kernel module, but not loaded (#140, thanks @abelbeck)
+- Assume '-6' if the binary is named 'fping6' (this is mostly for special
+  embedded-distro use cases, and not meant to be used generally in place of
+  compiling IPv6-only binary or using '-6', see also the notes in #139, thanks
+  abelbeck)
+- Get rid of warning "timeout (-t) value larger than period (-p) produces unexpected results"
+  (#142, thanks @MrDragon1122)
+
+
+fping 4.1 (2018-09-17)
+======================
+
+## Bugfixes and other changes
+
+- Fix problem when socket fd is 0 (#125, thanks Ramón Novoa!)
+- Fix running on servers with disabled IPv6 (#118, thanks Simon Matter)
+- Allow running "fping -h" or "--help" even when raw socket can't be opened (#131, thanks @teto)
+- Fix build issue with FreeBSD and IPv6 (#132, thanks @gsnw)
+
+fping 4.0 (2017-04-23)
+======================
+
+## Incompatible Changes
+
+##### fping and fping6 unification
+
+fping and fping6 are now unified into one binary. It means that, for example,
+doing 'fping google.com' is going to ping the IPv6 IP of google.com on
+IPv6-enabled hosts.  
+
+If you need exact compatibility with old versions, you can configure and
+install fping twice: once for ipv4, and once for ipv6:
+
+    ./configure --disable-ipv6; make clean install
+    ./configure --disable-ipv4 --program-suffix=6; make clean install
+
+##### Option -n, not the same as -d anymore
+
+Option -n / --name is now doing a reverse-DNS lookups on host addresses,
+only if they are given as IP address, but not for hostnames. For example,
+if you write 'fping -n google.com', fping would previously do a
+forward-DNS lookup on google.com, and then a reverse-DNS lookup on the
+resolved IP address. Now, it is just going to keep the name 'google.com'.
+That same behavior can be achieved with the option -d / --rdns (which was
+previously an alias for -n).
+
+                     fping<4.0              fping>=4.0
+    fping -n NAME    NAME->IP->IPNAME       NAME
+    fping -d NAME    NAME->IP->IPNAME       NAME->IP->IPNAME
+
+##### Discarding of late packets
+
+fping will now discard replies, if they arrive after the defined timeout
+for reply packets, specified with -t. This change is relevant only for the
+count and loop modes, where the measured times should be now more
+consistent (see github issue [#32][i32] for details).
+
+To prevent loosing reply packets because of this change, the default
+timeout in count and loop modes is now automatically adjusted to the
+period interval (up to 2000 ms), but it can be overriden with the -t
+option. The default timeout for non-loop/count modes remains 500 ms.
+
+##### No restrictions by default
+
+fping will not enforce -i >= 1 and -p >= 10 anymore, except if you
+'./configure --enable-safe-limits'.
+
+The reasoning to removing the restrictions by default, is that users can
+clog the network with other tools anyway, and these restrictions are
+sometimes getting in the way (for example if you try to ping a lot of
+hosts).
+
+##### Default interval (-i) changed from 25ms to 10ms
+
+The default minimum interval between ping probes has been changed from
+25ms to 10ms. The reason is that 25ms is very high, considering today's
+fast networks: it generates at most 31 kbps of traffic (for IPv4 and
+default payload size).
+
+## New features
+
+- Unified 'fping' and 'fping6' into one binary ([#80][i80])
+- Long option names for all options
+- IPv6 enabled by default
+- New option -4 to force IPv4
+- New option -6 to force IPv6
+- Keep original name if a hostname is given with -n/--name
+- Option -d/--rdns now always does a rdns-lookup, even for names, as '-n' was doing until now
+- Enforce -t timeout on reply packets, by discarding late packets ([#32][i32])
+- Auto-adjust timeout for -c/-C/-l mode to value of -p
+
+## Bugfixes and other changes
+
+- -i/-p restrictions disabled by default (enable with --enable-safe-limits)
+- Default interval -i changed from 25ms to 10ms
+- Fix compatibility issue with GNU Hurd
+- A C99 compiler is now required
+- Option parsing with optparse (https://github.com/skeeto/optparse). Thanks Christopher Wellons!
+- New changelog file format
