详细关于版本的说明文档，请看这里，
for windows：
for Mac：

1、支持iMac Pro 和MacOS High Sierra系统版本10.13.2
（一些不小心升级了系统到10.13.x发现PT12故障重重的童鞋现在要喜大乐奔了吧）


Pro Tools 12.8.3 是完全合格的使用与 macOS High Sierra (⚠️官方建议务必升级到10.13.2这个系统版本)。运行 macOS High Sierra 10.13.1 的用户应该在安装 Pro tools 12.8.3 之前更新到 10.13.2, 因为安装程序有问题。


热心的人告诉我们, 他们与苹果公司密切合作, 开发这个版本, 这将带来显著的回放性能改善, 同时苹果的新的 iMac Pro。Avid公司声称, 新的 imac Pro 比之前推出的27英寸的 imac 视网膜5K+I7 Cpu机型 (2017) 相比：


在 iMac Pro 8 核心机型上可运行更多36% 的 AAX插件
在
iMac Pro 10 核心机型上可运行更多62% 的AAX插件



2、未来新版本将会终结了对于windows7系统版本的支持
Pro Tools 12.8.3 是最后一个版本, 将支持 Windows 7;12.8.3 后的版本将不会在 windows 7 上进行测试, 并且任何 windows 7 特定的新 bug 都不会被修复。请升级到 Windows 10 之前更新到 Pro Tools 版本过去12.8.3。
3、Avid Video Engine视频引擎支持了新的编码格式
Pro Tools 12.8.3 视频引擎开始支持XAVC Long GOP 文件格式和 1080p50工程项目类型，改进后期制作工作流的集成化。
4、什么是 XAVC Long GOP files?（这个关于视频类的文件格式在音频网站就没必要坐重介绍了吧，笔者打算偷个懒，😄，有兴趣的朋友，可以自行用翻译机翻译）
XAVC is always going to involve some form of H.264 video, along with uncompressed LPCM audio. XAVC generally uses the MXF wrapper, with the audio and video in a single file.
GOP is an acronym which stands for Group of Pictures. Both Panasonic and Sony offer both i-frame (intra frame) and Long GOP versions of H.264. The i-frame versions compress every frame individually, and require a higher bit rate to achieve the same picture quality) but they are easier to edit with older computers with older editing software.
Long GOP versions only include some complete frames and then include the differences between frames after that until the next complete frame. This makes long GOP versions more efficient, which will give higher quality at a lower bit rates.
XAVC can also be either intra-frame or inter-frame. In the video community, these have come to be known as XAVC-I and XAVC-L (for long-GOP or inter-frame).
当然Pro Tools 12.8.3也修正了之前版本出现的部分bugs，特别是一些PT12.8.2用户在MacOS High Sierra10.13.x版本下遇到一些奇奇怪怪的故障。
