Does Erlang R15B02 have support for hybrid heap?

I run configure --enable-hybrid-heap blabla... and make it, but no [hybrid-heap] flag showing:

$ erl
Erlang R15B02 (erts-5.9.2) [source] [64-bit halfword] [smp:16:16] [async-threads:0] [kernel-poll:false]

I get to know this flag from here: https://stackoverflow.com/a/1185490/940313

The experimental Hybrid heap implementation is gone in R15B02:

OTP-10105  Remove all code, documentation, options and diagnostic
       functions which were related to the experimental hybrid heap
       implementation.

See http://www.erlang.org/download/otp_src_R15B02.readme

  • Thanks. However, I don't understand why is it gone? Do you have any idea? – Xiao Jia Nov 13 '12 at 14:26
  • It was experimental and the OTP team did not want to try to keep it alive going forward with the changes they are currently making to the system. I think the change paves the way for a better heap implementation further down the road though. – I GIVE CRAP ANSWERS Nov 13 '12 at 15:02
