The two major updates in this release candidate are #460 and #461.
We introduced a new data structure matrix in #460 to displace the default map for managing connections internally, with the help of this new data structure, we can eliminate the pointers in map and store connections in the form of a matrix (an array of slices), which will significantly reduce GC (Garbage Collection) latency:

The more connections there are, the more pronounced the effect.
While we have performed sufficient testing on matrix, we are still using map as the default connection storage in this RC version for the sake of caution, but you can enable the new data structure by specifying build tags: -tags=gc_opt. This can be considered as a precautionary measure so that in case matrix has any unexpected bugs, you can quickly fall back to the default map. We will consider promoting matrix to be the default storage for connections in a subsequent official release.
Another significant leap is #461, you can now run gnet on Windows, it should be noted that the Windows version of gnet is intended for development purposes and is not recommended for use in production.

Today, I'm thrilled to announce the release of gnet v2.0.0, in which we've made plenty of significant improvements and optimizations: added and removed some APIs, redesigned and reimplemented the buffer, optimized the memory pool, etc.
Please visit the blog post of announcing gnet v2.0.0 for more details.
