   1 July 30, 1995, v2.00.beta:
   2         0. the first release and beta version.

   4 Sep. 11, 1995, v2.10:
   5         1. Porting to AIX 3.x and 4.x, by writing dlopen(),
   6            dlsym(), dlclose() interface.
   7         2. Tested on SCO OpenServer 5.x
   8         3. Awared of that, unlike s700/s800, exported function
   9            symbols on HP9000 s300/s400 will be prepended with
  10            a '_' prefix by compiler(and this '_' prefix is not
  11            automatically handled by shl_findsym()). Now, it works
  12            fine on s300/s400.
  13         4. Support driver ODBC call tracing.

  15 Oct. 12, 1995, v2.11:
  16         5. Driver's SQLNumResultCols() will automatically be
  17            invoked in driver manager's SQLExecute(),
  18            SQLExecDirect() and SQLParamData() after successfully
  19            (i.e. return SQL_SUCCESS or SQL_SUCCESS_WITH_INFO )
  20            calling of their correspondent driver functions. This
  21            simplifies the state tracing/checking of the driver
  22            manager a lot and allows store procedures to return
  23            result set and also make iODBC driver manager work
  24            properly with SELECT INTO statements which actually
  25            don't return result sets.
  26         6. Memory leaks are cleared.
  27         7. Two bugs in dld.c for AIX are fixed
  28         8. A bug of setting tracing option is fixed.
  29         9. The driver will not be unloaded by SQLDisconnect()
  30            but by SQLFreeConnect() or next SQLConnect()/
  31            SQLDriverConnect()/SQLBrowsConnect() on a different
  32            driver. This will save driver's loading time if it
  33            has been used by a previous connection(even there
  34            is no active connection on this driver).
  35         10.Another three platforms are supported:
  36                 FreeBSD                 2.x
  37                 Concurrent Max/OS SVR4  1.x
  38                 DG/UX                   5.x
  39         11.autoconfig and build -- shell scripts to help modifying
  40            Config.mk and building iodbc driver manager
  41
  42 Nov. 12, 1995, v2.12
  43         12.I realized that a driver manager doesn't aware of
  44            difference between a C5 (i.e. hstmt) and a C6
  45            (i.e. transaction) states.
  46         13.The link flags "-lc" has been droped from Linux ELF
  47            section of Config.mk to fix a segment fault problem.
  48            Now, it works fine on Slackware 2.3 and Red Hat 2.0
  49            (kernel version are 1.2.xx and 1.3.xx respectively).
  50         14.On FreeBSD 2.x, dlsym() doesn't handle the '_' prefix
  51            prepended to an exportting function symbol by compiler.
  52            So, CLI_NAME_PREFIX needs to be defined as "_SQL" for
  53            FreeBSD 2.x.
  54         15.Some files are renamed
  55                 dld.c   -> dlf.c
  56                 dld.h   -> dlf.h
  57                 confg.h -> config.h
  58         16. Fix a bug on setting tracing options.
