No. There was no "issue" in AmiBroker.
It is Windows thing. Simply Windows despite having
for example 2GB of "free memory", fails if you want to allocate 1GB
because the memory is fragmented from the very start in Windows.
For example, certain Windows-own DLLs have preferred load address
just in the middle of address space - cutting available largest block
by half.
It is illustrated on the screenshot from the VMMap showing address
space of Windows Explorer.
Microsoft published fix for that problem for IE7
http://support.microsoft.com/kb/950060
But it is exactly re-occuring in IE8 and all new versions of OS.
The change in AmiBroker was an attempt to partially address this OS
problem, by moving AmiBroker DLLs into different place in the VM address
space freeing some extra space. This is not cure but some kind of
improvement over situation created by Microsoft in recent versions of OS.
I could easily just say: oh well.... complain to Microsoft. Instead
I proactively try to address/workaround OS inefficiences to get the most
possible from the hardware and OS that you have installed.
Change Log mentions things by version. So if given thing appears under
CHANGES 5.28.1 it means that it is added in that particular version.
