- `.from(t1, t2)` produces an unconditional join if you forget to add a condition in the .where() sqlpp11 therefore now deprecates unconditional joins. - more often than not, writing something like `where(name == "doe")`, you meant to write `where(t.name == "doe")`. It is hard to find bugs when the former expression compiles because you happen to have a variable `name` in the current scope as well. sqlpp11 therefore now deprecates `.where(bool)` and disallows raw bool values boolean expression like `something and bool` wrap bools in sqlpp::value(), if you REALLY want a bool value here
