### - Changes in 1.7.40679 and later versions

{% hint style="info" %}
The <mark style="color:orange;">static library</mark> is only available up to <mark style="color:orange;">\_v140\_,</mark> you can use the <mark style="color:orange;">static library</mark> for <mark style="color:orange;">VS2015(v140)</mark> in later versions.
{% endhint %}

<figure><img src="/files/NJznzVx4vdSCh86zm9Jv" alt=""><figcaption></figcaption></figure>

1. With the latest XCode, only arm64-specific libraries are available, so we have prepared both the **old XCode** and the **latest XCode**.
2. We are discontinuing support for <mark style="color:orange;">r10d</mark>, but will continue to support <mark style="color:orange;">r13b</mark> and <mark style="color:orange;">r17</mark>.
3. The version name of the tool chain used in the build disappears from the path and <mark style="color:orange;">cmake</mark> is replaced.
4. The STL type name used in the build has disappeared from the path. Instead, the combination string “*Toolchain name used for build + Configuration*” is entered in Camel notation at that location.
5. The number of Architecture names in the path has increased to three. This is because we're bringing back support for x86 and starting to support ARMv8 for 64-bit.
6. VS version names in the form of VS2017 have been replaced with version names in the form of v141 in the path.
7. VS2017 ->   <mark style="color:orange;">v141</mark>
8. The library for Linux was split into two files, one for the client and one for the server, with a single unified file combining the client and server modules.\
   \
   **For clients:** <mark style="color:orange;">libProudNetClient.a</mark> \
   **For servers:** <mark style="color:orange;">libProudNetServer.a</mark>
