Version 1.0 (06-MAY-2005)
===========================================================================
Changed default schema from xxtascha to tascha.

Added admin procedures to drop tasks and schedules.

Fixed bug when checking first/last DOM. Getting invalid date from
NEXT_DAY if TO_CHAR(SYSDATE,'D') returns '0'. Used 'DY' instead.

Changed taschx_pkg and tascha_pkg to use raise_application_error()
rather than packaged exceptions. User will see error then as they
are not likely to ever call procs inside exception block.

Added run_stats option against schedule to log session statistics after
task completion.


Version 0.9 (20-APR-2005)
===========================================================================
Changed logging to not require sched_id and run_no as parameters. These
are set through package variables instead when a task is called.

Added tascha_logger package so all users can be granted access to logging
procedures without having access to admin procedures. Makes things easier
for end users to write to tascha log from their procedures.

If no failure email address is specified then use admin address specified
at install instead.

Added title for schedule entries so sub titles can be specified. For example
the task may titled "Salary Report" but two different schedule entries could
be titled "Increases" and "Pending" to reflect variations caused by different
input parameters.

Added dbms_application_info calls so jobs can be viewed in v$session.

Included wrapper for dbms_stats.gather_schema_stats and included task to
analyze tascha schema. Wrapper for dbms_stats required as we cannot use
booleans - dbms_sql does not support them.

Split logging table into two. Header table task_logs and details table
task_log_lines. Added utils/show_logs and show_log scripts for easier
viewing of logs.

Version 0.8 (10-MAR-2005)
===========================================================================
Added logging to triggers on tasks, task_schedule to catch schedule changes

Included maintenance task for task_logs table.
Procedure task_log_maint. Task disabled as default.

Added option for DOW to be MON, TUE, etc rather than just 1, 2, etc.
These are converted to 1, 2 equivalents at run time using date format 'D'

Made reschedule_task raise an exception when invalid schedule id used.

Moved scripts into sub-directories to tidy up installation.

Included topqueries example.
topqueries.sql is procedure to be created as priveliged user.
topqueries_req.sql is pl/sql to create task as tascha admin user.

Changed logging procedures to cache logs to arrays and flush on request

Version 0.7 (20-FEB-2005)
