>> SPEED then JIT is the way to go. Early estimates indicate that the new
>> Dolphin will be between 2x and 5x faster than Dolphin Professional X6.
>>
>> 2) Multi-threading. Currently, the Dolphin VM is single threaded
>> (although with an ability to run external calls on separate threads).
>> The Vision Smalltalk VM is true multi-threaded which will allow Dolphin

>> multi-processor and multi-core machines.
>>
>> 3) Unicode Support. Internally, the new VM is entirely based on Unicode.
>> For many of our international customers the ability to use Unicode in
>> their applications will be a huge benefit.
>>
>> 4) Smalltalk Link Libraries (SLLs). In the same way that Digitalk
>> Smalltalk introduced the concept of SLLs, the Vision Smalltalk platform
>> also allows Smalltalk code to be distributed as collections of small,
>> pre-compiled units that in many ways are simailar to Windows DLLs.
>> Dolphin Smalltalk users will be able to deploy their applications either
>> as SLLs or fully bound into executable files as they are today.
>>
>> 5) 64 bit OS Support. Whilst the current Vision Smalltalk VM is 32 bit,
>> development is underway on a full 64 bit version. Once this is ready,
>> new Dolphin users will be able to benefit from this immediately with no

>>
>> 6) Maintenance and Support. The Vision Smalltalk platform is fully
>> supported and is being actively developed by Lesser Software. With this
>> new way forward both existing and new Dolphin developers can be sure of
>> a supported route into the future.
>>
>> At present, no pricing structure has been set for the new platform.
