I would say not quite in the same manner, allocation is a pretty old topic that had only slow and slight changes over time, so most of the existing material is still relevant, but some parts have shifted over time, like for example names in the standard library:
GeneralPurpouseAllocator -> DebugAllocator or using more data structures with an unmanaged style (allocating functions directly have an allocator parameter).
Also the Docs on this forum started mostly as filling holes in documentation that didn’t exist anywhere else.
I think regarding allocation and memory it is a big mixture of articles and links spread across the internet. @vulpesx already mentioned Ziglings and that is a great base for learning.
Then you could look at Learning Zig :
Followed by Ziggit Docs about memory management

It would be very helpful if you let us know which resources you find that are up to date and relevant and helped you understand specific parts. (It is difficult to look at it from a beginner perspective after a while) Then we could try create a good overview document together or this topic can evolve towards that.
There are also a lot of topics on this forum about different specific aspects of memory-management
Because some of the older material will show dated main examples on how to get an allocator, make sure to take a look at the juicy main link @spiffyk posted.
