And here is working script to load it:

Metacello new
�� �� �� �� smalltalkhubUser: 'Pharo' project: ���Seamless';
�� ����configuration: ���Seamless'; �� �� �� ��
�� �� �� �� version: #stable;
load

Loading by Gofer or directly by configuration is not working now (it is really strange)

Hi,

I released new version of Seamless 0.9.0.
It is based on specialized TostSerializer instead of Fuel.

This version is ~4 times faster than previous one and produce much compact data packets.��
For example Fuel based version takes 400 bytes to return small integer as result of message send. Now it is just 21 bytes.

Pharo 5 and 6 are supported.
