+ <item>
+ <p>
+ Improve search algorithm of abandoned memory carriers.
+ Instead of limited linear search, each allocator instance
+ maintain a balanced search tree of all its abandoned
+ carriers for faster and more exhaustive search.</p>
+ <p>
+ Own Id: OTP-14915 Aux Id: ERIERL-88 </p>
+ </item>
+ <item>
+ <p>
+ New erts_alloc command line options <c>+M_acnl</c> and
+ <c>+M_acfml</c> to limit carrier abandonment.</p>
+ <p>
+ Own Id: OTP-14916 Aux Id: ERIERL-88 </p>
+ </item>
+ <item>
+ <p>
+ New family of <c>erts_alloc</c> strategies: Age Order
+ First Fit. Similar to "address order", but instead the
+ oldest possible carrier is always chosen for allocation.</p>
+ <p>
+ Own Id: OTP-14917 Aux Id: ERIERL-88 </p>
+ </item>
+ <item>
+ <p>
+ Add possibility to change allocator options at runtime
+ with <c>system_info(erts_alloc, ...)</c>. Only option
+ <c>sbct</c> (single block carrier threshold) is currently
+ supported via this interface.</p>
