Dear Boosters, In my opinion it would be very helpful if the documentation include for each library the version of the last update. For instance, one could add this information in the summary page (http://www.boost.org/doc/libs/1_41_0): --- [snip] --- uBLAS uBLAS provides matrix and vector classes ... Author(s)...........Joerg Walter and Mathias Koch First Release...1.29.0 -> Last Update......1.40.0 <- Standard Build & Link......Header only Categories........Math and numerics --- [/snip] --- The reason for this is that it should simplify the discovery of what version of Boost one needs for his own software project. As a matter of fact, the use of "First Release" might not be sufficient because after the initial release of a library many other features could have been added. So the need for this additional piece of information. What do you think? Regards, -- Marco
