[Pywikipedia-l] ArchiveBot

Hi all. I found this notice on User:MiszaBot III page [1] *All archiving tasks which used to be performed by the MiszaBots are now performed by lowercase sigmabot III <https://en.wikipedia.org/wiki/User:Lowercase_sigmabot_III> without the need to change the {{User:MiszaBot/config}} configuration. The actual MiszaBots are neither functioning nor expected to become functional.* And on Lowercase_sigmabot_III page I found: *This bot was created to replace MiszaBots <https://en.wikipedia.org/wiki/User:MiszaBot> after the latter stopped working and uses an identical configuration syntax.* Few questions: 1) I guess that MiszaBot III was using archivebot.py (his name is in the list of contributors). Is that right? 2) does the statement above implies in some way that archivebot.py has flaws, which has been fixed by sigmabot III (the code in his/her page is different from archivebot.py)? Or the latter just chose another implementation for other reasons? Can someone shed some light? Thanks Mpaa [1] https://en.wikipedia.org/wiki/User:MiszaBot_III [2] https://en.wikipedia.org/wiki/User:Lowercase_sigmabot_III
