+! Copyright update [doc]
+
+! C++11 support is not trully header only [c++11]
+
+! Statement name truncation in PostgreSQL
+
+  There seems to be a limit on the prepared statement name in PG. The result
+  is that the names are no longer unique (statement already exists error).
+  What we can do to help with that is put the statement kind (perists, find,
+  etc.) part at the beginning of the name rather than at the end as we do
+  now.
+
+  See email from <abellina@gmail.com>/11-Jun-2014.
+
+- Add noexcept to move construction and assignment [c++11]
+
+  Without noexcept some code (e.g., swap()) may have to resorts to copy.
+
+! Command Line Tools required for ODB binary package on Mac OS
+
+  It seems without them there are no standard headers in /usr/include. Need
+  to test and document.

+Some existing value types (e.g., time_period in Boost.DateTime) do not
+provide modifiers and the only way to initialize such types is by passing
+everything at once in a constructor. For such types it would be nice to
+be able to use another, "interface" type to capture the data and then
+use it to initialize the desired type at once. The same logic would
+apply to persisting the type in the database.
+
+In fact, we already can do this via virtual data members just very
+awkwardly -- one has to specify the interface type (as virtual member
+type) as well as to/from conversion functions (as accessors and modifiers)
+for every data member of the target value type. So it seems pretty
+straightforward to allow specifying this once for a type.
+
+We already have a very similar mechanism: extended database type support.
+The only difference, really, is that there it is about database types and
+here it is about C++ types.
+
+Tricky stuff:
+
+  * There can still be accessor/modifier expressions at the element
+    level (will have to compose the calls).
+
+  * Containers could be tricky: for them we require by-reference
+    access. Yes, containers might not even be supported since we
+    do simple value and container init in separate functions so
+    a stack-based temporary won't work. This will probably be ok,
+    however, since the use-case is to facilittate mapping of existing
+    composite value types and it is unlikely they will use containers
+    (or maybe not).
+
+This will need to be implemented as "for all intents and purposes use this
+other type as the composite value type except in two places: when getting
+const& from the object and when setting value (std::move()?) to the object."
+
+Could this be something that's also useful for simple value types? Yes! Real
+use case: custom lazy ptr (implements loading in ->). Being able to use
+standard lazy ptr as interface type would be useful. Right now have to go
+through virtual data members. Not going to work well for templates though.

+- Interface type for existing composite value types: interface-type

+- Make column prefix for locally-defined composite value types empty
+
+  If a composite value type is defined in a class, then we could make
+  its table prefix empty by default. This will remove the ugly need to
+  specify an empty prefix for deleted_data. Of course, if it is used
+  for several data members, then we will end up generating broken code.
+  Maybe if it is private and only used for a single data member?

++ stderr_tracer doesn't trace statement preparation [2.4.0]
+
+  If a statement is invalid, then it will fail during preparation. However,
+  currently, there is no way to see that statement since stderr_tracer doesn't
+  trace this event.
+
+  Options:
+
+  * trace preparation by default - too much info
+  * allow changing behavior at runtime - not thread safe
+  * support via bool flag and make user instantiate - burdensome
+  * support via bool flag and instantiate stderr_full_tracer - code bloat
+    but seems the best option
