| should still be able to use the old API if it is desired.
So far we have retained backward compatibility. But our plans are to
drop the old APIs as soon as all of the utilities (including external
projects) report they are ready.
I seriously recommend everyone to use the Unified Driver Model (UDM)
interface. It has numerous enhancements
* No global variables (thread safety).
* Unified driver interface. Internally abstracts all inband,
outofband and probing drivers.
* Easier and cleaner API interface, fewer number of arguments.
* It is easy to maintain UDM APIs unchanged across future releases
because of its design.
* LAN driver in UDM has serious enhancements and bug
fixes. "per-message-auth" support will be enabled based on
'get-channel-auth-caps' returns automatically. This will be a big
performance improvement (fewer bytes to transfer, one time password
* Buffers re-used where ever possible through ipmi_device_t. This
avoids unnecessary memory copying and allocation.
0.1.3 APIs impose a serious limitation if we want to move
forward. Every IPMI command needs to be written for each driver and
utilities becomes will go crazy supporting all the drivers. I can
retain the old APIs till all utilities gets ported to newer APIs. But
they will get no new enhancements.
Coding freezing and QA releases will happen by end of October and
Final release tentatively planned around end of November.
I wish I can drop the APIs and have a clean start from 0.2.0
onwards. Our next major focus will be towards SOL support.
