   NOTE: Next major version will comply with the emerging common
         database interface DBI, if agreed by the R-SIG-DB.  This 
         will probably change the function names, but not the basic 
         functionality.

Version 0.3-3

* Some minor clean up of the RS-DBI C code.

* Updated the use of NAs in strings in the C code, according to the new 
  1.5.0 stricter rules.

* added a PROTECT() when re-setting the length of output data.frame 
  during fetching that could lead to random core dumps (thanks to 
  Don MacQueen for reporting this pesky bug).

* getInfo() on a connection object now also returns the password used
  on the connection (needed, e.g., in assignTable, see below).

* A few fixes to assignTable.OraConnection:

    A bug in the SQL*Loader script that assignTable() creates to
    efficiently transfer data.frames to Oracle (the bug was that NAs in
    the last column caused SQL*Loader to fail);

    assingTable() now also provides the password in the call to SQL*Loader 
    to avoid being prompted for it.

    Added an argument "batch=10000"; this is used to write.table() these
    many rows at a time from the data.frame in order to avoid huge memory 
    build ups.  It's still shamefully slow (due to write.table), but at least
    it won't exahust memory. [Need to find an efficient alternative to 
    write.table(), perhaps we need to write our own specialized C code?]

* Extended the size of the internal connections parameters (user, password 
  and dbname) to 1024 to allow users to embed the tnsnames.ora string, e.g.,

     con <- dbConnect(Oracle(), 
             "user/passwd@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=foo.misc.de)(PORT=1521))(CONNECT_DATA=(SID=TEST))

  [this seems to be an undocumented "feature" that Oracle gurus use quite
  commonly when they don't have priviledges to update the network config
  file $ORALCE_HOME/network/admin/tnsname.ora (thanks to Michael Mader for 
  this trick!]

* ifdef all S4/Splus' idioms if(IS_LIST(x)) x = AS_LIST(x).  I'm not sure
  whether these should be PROTECTED in R, but since the idiom is only
  needed in S4/Splus5+, it's better not to have it in R.

* Fixed a bug in SQLDataType.OraConnection (wrong signature).

* Added dbObject validity checks to a bunch of the meta-data functions.

Version 0.3-2

* Added code to be able to copy data.frames to Oracle, see
  assignTable().

Version 0.3-1

* Note that if you statically link against the Oracle libraries
  you may move the resulting package to systems w.o. Oracle (of
  course, subject to the other system being binary compatible).
  If you do this, you may need to provide additional Oracle
  configuration parameters to ROracle.  See the file "README.client"
  for details.

* Ported to R, added a configure script.  

* Implemented a workaround to the very nasty bug in the linux
  implementation of the ProC/C++ (as of 8.1.[567]) (see the function
  filter_buggy_error() in RS-Oracle.pc) The sign was that Oracle
  would give a "fetch out of order" error when there was no fetching
  going on.

* Modified the documentation to pass R CMD check. Unfortunately we now
  have two separate versions of the help (one for Splus, another for R).

Splus-specific

* It nows does the  #include "S.h" conditionally, for the sake of 
  Splus 6.0 (you need to define the macro SPLUS6 in the makefile).
