In July 2016 IBM has released Informix 12.10xC7. Just a couple of weeks after the regular fix pack 12.10.xC7 IBM launches 12.10.xC7W1. Due to this some customers assumed that the fix pack is buggy. But this is definitely not the case! Instead the PID refers to COGNOS - offering specific requirements which had to be implemented into Informix which is the embedded database. Probably IBM will provide customers with more PIDs in the future.

Important: if you have already installed Informix 12.10xC7 it is not necessary to install the PID afterwards. The fixes will be reconsidered in the next fix pack 12.10xC8.

The new fix pack can be called an I(nternet)o(f)T(hings)-Release. It comprises mainly enhancements in the field of JSON/BSON, Spatial Data and TimeSeries. Informix can now receive data via MQTT protocol and put in into the database directly. This is Important to allow sensors and other endpoint devices to send data to repositories or message brokers. 

Finally there is something new from the Informix Warehouse Accelerator (IWA). From now on you can install the IWA also on IBM POWER8. So far installation was possible only on Intel processors (x86).
