inet:setopts([{active,once}]) wakes up IO polling thread unnecessarily, leading to lock contention and visibly higher CPU utilization.

- Application(s):
- erts
Two bugs in the ERTS internal thread wakeup functionality have been fixed. These bugs mainly hit when all threads in the system tried to go to sleep. When the bugs were triggered, certain operations were delayed until a thread woke up due to some other reason. Most important operations effected were code loading, persistent term updates, and memory deallocation.

Fixed bug in ets:select_replace/2 on compressed tables that could produce faulty results or VM crash. Bug exists since OTP 20.

When compiling Erlang/OTP on macOS using Xcode 12, the performance of the BEAM interpreter would be degraded.

As of OTP 22, the allocator specific memory carrier pools were replaced by a node global carrier pool. This unfortunately caused substantial memory fragmentation in some cases due to long lived data being spread into carriers used by allocators mainly handling short lived data.
A new command line argument +M<S>cp has been introduced with which one can enable the old behavior as well as configuring other behaviors for the carrier pools. In order to configure the old behavior, with allocator specific carrier pools for all allocators, pass +Mucp : (including the colon character) as a command line argument to erl when starting the Erlang system.
The default configuration for carrier pools will be changed to +Mucp : some time in the future, but not in this patch.

The configuration parameter memsup_improved_system_memory_data has been introduced. It can be used to modify the result returned by memsup:get_system_memory_data(). For more information see the memsup documentation.
Note that the configuration parameter is intended to be removed in OTP 24 and the modified result is intended to be used as of OTP 24.
