Starting with Soyuz TMA-5, the H2O2 system had already been improved, resulting in a slight life-duration extension. I doubt they can do better with this system (SIOS) : I guess they should make a major redesign of it.

AFAIK, They are same but some corporations and agencies are using different designations.

But there are a difference of two years, or maybe one year and some months.

there may not have been an actual improvement in the H2O2 system for TMA-5, but rather experts from Energia re-qualified the system from 180 days to 210 days.

The later date almost always wins.

There have been actual improvment : system СТЭО (Система Термоэлектрический Охладитель) !

Don't rule out a better containment system for the Soyuz-MS H202.

agreed; more on the h2o2 system
http://suzymchale.com/ruspace/soyuz.html
There will also be an improved cooling system for the hydrogen peroxide re-entry control thrusters, enabling the Soyuz to remain in space for up to a year. The ship would be designated Soyuz TMA-Ts, «Союз-ТМА-Ц», the “Ts” meaning Цифровой, Tsifrovoi, digital (later changed to “M”, presumably for “Modernized”).

Soyuz TMA-MS does not exist. There will be Soyuz MS beginning with factory number 731. In FPIP schedule in L2 section we can see Soyuz TMA-M with number 722 and launch in September 2016. I doubt that the next ship in November 2016 will be 731 due to presence of only one Russian on board it. That is why the first Soyuz MS launch can not be earlier than March 2017. Soyuz MS will be Soyuz TMA-M with fully modernized and tested systems. The date of first Soyuz MS launch depends on results of first flights of Progress MS ships too.

Maybe they will use the same procedure that was used when the change from Soyuz TMA to Soyuz TMA-M occured. So after the launch of "731" they can launch "720" to "722". The numbers in the FPIP can be changed.

Perhaps what has confused things slightly is that the rockets were ordered for «Союз-ТМА» № 709, 711, 713, 714, 731, 732, 734, 735, 737.

FYI. Upgrade of the Progress-MS.

"In particular, it will be replaced on-board radio system," Quantum-B "antenna-feeder devices on a single new command and telemetry system ECTS. Moreover, instead of the existing equipment rendezvous and docking" Course A "new" progress MS " system will be installed "Course-NA" which will go to the modern element base with the organization of production in Russia ", - said the deputy head of the RSC" Energia ".

Upgraded ship will also receive additional protection from debris and meteoroid on a cargo edema. To increase reliability of the docking mechanism and joint sealing will be introduced duplicate motors.

"Progress-MS" will be equipped with the new headlamp with light-emitting diodes, instead of radio monitoring equipment orbit as part of traffic control systems and navigation will be applied satellite navigation equipment of last generation.

Most, if not all, of these new technologies have already been demonstrated on earlier Progress missions on a one-shot basis.

On each Progress-MS, there will be four containers to allow the jettison of 24 CubeSat !

Maybe an intelligent attempt to use payload mass increase due to the use of Soyuz-2.1a ?
