Known Issues in 2018.4.16f1
Animation: Animator.Update CPU time spikes when multiple animations are playing (1184690)
Asset Bundles: Building asset bundles when build path doesn't exist causes a failed assertion on "pluginAppendices.size() <= 1" (1203242)
Package Manager: Immutable packages altered by the API Updater are reverted to their original state when packages are resolved, which can lead to slower import performance in that context.

Package Manager: Changed the package installation process to no longer set package directories and files as read-only on disk. This prevents all sorts of possible corruption scenarios (e.g. read-only directories, partially-read-only packages in the package cache) and avoids some permission issues when removing packages.
Package Manager: Changed the package installation process to systematically revert packages to their original state. Note: this has the side-effect of actively reverting local modifications in immutable packages, which could previously be kept until the dependency was updated to a different version of the package. In order to preserve local changes, a package should first be [embedded in the project](https://docs.unity3d.com/Manual/upm-embed.html).
Package Manager: Added support for configuring additional SSL certificate authorities, including self-signed certificates. See the [Unity Manual](https://docs.unity3d.com/Manual/upm-network.html#SSL) for more information on how to use this.

Package Manager: Added support for Git URLs without a trailing
git://URLs or prepending
git+to URLs (e.g.
Package Manager: Added support for tarball-based dependencies (e.g.
Package Manager: Changed the
UnityEditor.PackageManager.Client.Addmethod to make the
@prefix optional when adding Git-based dependencies and local dependencies (
Package Manager: Reduced the amount of data transferred over the network when fetching package metadata from the registry.
