internal charset to one associated with currently being handled query. 
To note such a query can come from interactive client either.

There was a discussion within replication team and Monty who's suggestion won.
It avoids straightforward parsing of all `set' queries that could affect client side 
character set. 
According to the idea, mysql client does not parse `set' queries but rather cares of
`charset new_cs_name' command.
This command is generated by mysqlbinlog in form of exclaiming comment (Lars' suggestion)
so that enlightened clients like `mysql' knows what to do with it.

Interactive human can switch between many multi-byte charsets during the session 
providing the command explicitly. 
To note that setting new internal mysql's charset does not
trigger sending any `SET' sql statement to the server.

When an ambiguous field name is used in a group by clause a warning is issued
in the find_order_in_list function by a call to push_warning_printf.
An expression that was not always valid was passed to this call as the field
name parameter.

Fix for extra zero in exponent of double values on windows.

A query with a group by and having clauses could return a wrong
result set if the having condition contained a constant conjunct 
evaluated to FALSE.
It happened because the pushdown condition for table with
grouping columns lost its constant conjuncts.
Pushdown conditions are always built by the function make_cond_for_table
that ignores constant conjuncts. This is apparently not correct when
constant false conjuncts are present.

which was fixed by earlier changesets.
The error message is now the more generic "Unknown table ... in field list".
