Can you please try again the windows binary and let me know if the problem persists.

Well, perhaps not.
The Download page says 2.0.3, but when I start it says 2.0.2. in the app ?  Perhaps the windoes exe has not been updated.

Hi Team, 

Thanks a ton for the new features and improvements!

I'm just getting started and was trying to run web2py.exe on Windows 7 after downloading it from (2.0.2 stable).

However, ran into this error:

D:\web2py>web2py -S welcome
Traceback (most recent call last):
  File "", line 16, in <module>
  File "gluon/", line 15, in <module>
  File "gluon/", line 24, in <module>

  File "gluon/", line 264, in <module>
  File "gluon/", line 250, in read_possible_plurals
WindowsError: [Error 3] The system cannot find the path specified: 'D:\\web2py\\gluon\\contrib\\rules/*.*'

Then, realized there was no folder called "gluon" in the extracted folder. I downloaded the source from and copied the "gluon" folder from this source code to the previous web2py folder.

This solved the error and was able to web2py GUI. Hope this helps.

After 5 months. It is done. This is the most waited and the most feature-packed release.

I am sure we'll find some corners that need to be ironed but it is considerably better than 1.99.7. It adds lot of new features and improves many existing ones:

- 57,000 new lines of code and closed 279 issues since 1.99.7.
- Retrieving data from DB should be faster, in particular select(cacheable=True)
- Has a new scheduler, a built-in wiki, new language and pluralization system, better markmin with oembed support and better scaffolding app, increased security.
- Lots of experimental features including GIS support, mongodb support, built-in, and more.

Should be 100% backward compatible. If you run into any issue let us know ASAP.

I personally want to thank the major contributors to this release (in alphabetic order)
Alan, Andrew, Anthony, Bruno, Christian, Dave, Dominic, Iceberg, Jonathan, Marc, Mariano, Marin, Martin, Mark, Michael, Michele, Niphlod, Patrick, Vladyslav, 
They spend many nights testing, coding, debugging at a very fast pace.

Many many people have contributed.

If your contribution has not been properly acknowledged please let us know ASAP. It is probably an oversight.

- tasks are marked EXPIRED (if stop_time passed)
- functions with no result don't end up in scheduler_run
- more options: -E -b -L
- scheduler can now handle 10k tasks with 20 concurrent workers and with no issues
- new params:
    tasks can be found in the environment (no need to define the tasks parameter)
    max_empty_runs kills the workers automatically if no new tasks are found in queue (nice for "spikes" of processing power)
    discard_results to completely discard the results (if you don't need the output of the task)
    utc_time enables datetime calculations with UTC time
- scheduler_task changes:
    task_name is no longer required (filled automatically with function_name if found empty)
    uuid makes easy to coordinate scheduler_task maintenance (filled automatically if not provided)
    stop_time has no default (previously was today+1)
    retry_failed to requeue automatically failed tasks
    sync_output refreshes automatically the output (nice to report percentages)
- workers can be:
    DISABLED (put to sleep and do nothing if not sending the heartbeat every 30 seconds)
    TERMINATE (complete the current task and then die)
    KILL (kill ASAP)
