Thoughts for 5.8.2

Hi guys

Pickung up what Thiago's wrote in another thread recently -

> What about a release next week? I've just committed CORS support and 
> I'm looking forward to get it released. :) 

Here are my thoughts about the next release. Well done for adding CORS 
support, Thiago. It's a useful addition to Tapestry. Further, we have a 
number of smaller bug fixes and improvements. I'm all for releasing 
early, however, I think we should make an effort towards including the 
fixes for the issues listed below also:

TAP5-2718 Tapestry Announcement lacks version

TAP5-2714 Checkbox component with Bootstrap 4

TAP5-2721 Broken links to 5.8.1 asc files on download
           page (more a todo than a commit)

The above are probably not very complicated or challenging. Fixing them 
can make a difference for new users, though  - no second chance for a 
first impression.


TAP5-2713 ChecksumPath
I understand Ben already fixed this one, so the issue could be set to 
closed also.

TAP5-2723 CronExpression fails handling L-<dayOfMonth>
It would be nice if Charles didn't have to wait another few months for a 
fix. That said, I agree with Ben: the code in CronExpression isn't easy 
to understand and hence the cause of the problem not easily spotted. My 
small contribution so far is a test case which I added to the TAP5-2723 
branch. I won't have the time to work on it more during the next couple 
of weeks, so either somebody else picks it up or we just leave it until 
later.

Thanks,

Volker
