Just a friendly reminder to people that experimental isn't 
expected to be stable.
2.079 will come with this change, switch to stdx-allocator 
package if you prefer stability. stdx-allocator provides the 
current code and works down until 2.072.

https://code.dlang.org/packages/stdx-allocator

Also note that only vibe.d ~>= 0.8.3-alpha.1 and vibe-core ~>= 
1.4.0-alpha.1 use this package.
(though while most projects have been upgraded manually, I hope 
that we can get a new release of Vibe.d out there soon to avoid 
any issues - see [1]).
