Known BUGS

   o	There is a warning message about ambiguous slot choice in the integer 
	coercion of the connection con. (This is a bug in DBI packages.)

Changes in TSdbi version 2009.11-1

   o	Removed namespace export of "show", which seemed to be the cause of the
   	warning messages about "replacing previous import: show" when other
	packages require TSdbi.


Changes in TSdbi version 2009.5-2

   o	Added optional names argument to TSquery, to give series names to 
	returned series. 

   o	TSquery was extended to allow generating daily series. 


Changes in TSdbi version 2009.5-1

   o	Added class conType which is inherited by connections for specific
	drivers, so that some methods (in progress) can abstract from the 
	specific driver. 


Changes in TSdbi version 2009.1-1

   o	Added checks in several TS* packages to verify if a service is 
	available on the testing host (e.g. CRAN). 

   o	Minor documentation fixes found by new R-devel parsing. 

   o	Aliases for panels and vintages should now resolve properly (they did 
	not, other than "current").


Changes in TSdbi version 2008.11-1

   o	A mechanism has been added for (optionally) allowing different vintages 
	and panels of the data series. (e.g. series with the same identifier 
	but a different release date or country).

   o	More database plugins have been added  (PostgreSQL, ODBC, Fame). 

   o	A mechanism to support multilingual documentation as been added (but not
	yet well tested).
 
   o	The is support to specify what time series representation should be 
	returned.

   o	Vignettes have been expanded.

   o	The class representation of some objects was cleaned up and improved.

   o	renamed class TSdbOptions to TSdb and change TS*Connection classes to
	include it in their representation rather than with contains.

   o	changed fields refPeriod to refperiod in tables to avoid capitalization 
	issues among SQL version. Changed TSrefPeriod to TSrefperiod to avoid 
	confusion.

   o	changed tables Panels to panels and Vintages to vintages, to avoid
	confusion, but tables do not seem to suffer from the capitalization issue.  

   o	changed "double" to "double precision" and DATETIME to TIMESTAMP in 
	inst/TSsql/CreateTables.TSsql as these work in other SQL versions 
	as well as MySQL.


Changes in TSdbi version 2008.8-1

   o	adjusted TSquery to use standard sql extract(YEAR rather than mysql YEAR(.

   o	fixed bug in TSquery for case of a query returning only one period. 


Changes in TSdbi version 2008.5-1

   o	Work around for bug in R 2.7.0 

   o	Added TSquery (even though it is not logically part of this package). 

   o	Misc. clean up of beta. 

   o	vintages is working but not carefully tested. Panels may be working, but
	not at all tested.

   o	This is a beta version.

   o	This is a beta version.
