经过了几个月的工作这个相当大的更新终于完成了

As you may already know I’ve intended to give Nostalgia Shader the same sort of extensive overhaul that Kappa Shader recieved with version 4.0, thus there are many new things in this release. An example of that would be the addition of screenspace path-tracing as you already know it from Kappa Shader, which can be enabled in the settings and is also an automatically enabled part of the “Ultra” profile in the shaderpack settings. I have made some pack specific alterations of course, with the intention of it mirroring the looks of NostalgiaVX to have a viable free alternative, similar to the relationship between Kappa Shader and KappaPT.

正如你们已经知道的，我在为Nostalgia Shader的4.0版本添加一些类似于Kappa更新到的东西，因此这个版本里会有很多新东西，比如说你们已经在Kappa Shader中见过的SSPT（屏幕空间路径追踪），你可以手动开启或者在Ultra预设中自动启用，当然我还添加了一些特有的东西，以此来让Nostalgia Shader像是Nostalgia的一个免费替代版，就像是Kappa Shader和KappaPT之间的关系。

I have also put some of the new optifine features we’ve recieved earlier this year to good use, which not only helps with performance but also allows for much nicer overall visuals. This also allowed me to bring over many of the small internal improvements and updates of version 4 of Kappa Shader, which includes the much nicer auto exposure for example.

我还加入了一些Optifine的新特性，这些东西不仅可以提升性能而且能带来更好的整体效果，这样我也能把Kappa Shader的一些不错的更新和改动带过来，比如更好的自动曝光。

Ontop of that I have decided to do some touchups and overhauls on various elements of Nostalgia Shader, which you can especially see in the much more atmospheric visuals in the nether and the end dimensions.

除此之外我还决定做一些润色和大修，比如说你们现在能在末地和下界看到的效果更好。

Overall this update irons out the struggles version 3 had and brings the pack closer to the way I want it to be like, and I hope you’ll enjoy this update and that it’s worth the wait :p

综上所述这次更新解决了一些我在3.0版本纠结的东西，这样Nostalgia Shader也能更像我想让他变成的样子，我希望你们能享受这次更新，这也值得等待。

(Also excuse me resuing the screenshot gallery from this months devblog, but I am kinda running out of motives for “promo-screenshots”. I might have to start using some of the awesome shots people post on my discord server at this point, or ask some of them to make shots for these updates.)

Only 1.16.4+ is supported at this moment since the new OptiFine features have not yet been backported! Also needs OptiFine G7 or newer.

由于一些Optifine的新版本尚未被加入到更早的版本中，因此仅可在1.16.4+的版本中使用，并且需要Optifine的版本时G7或者更新的。
