Pywikibot compat will no longer be supported - Please migrate to pywikibot core

Sorry for English, I hope someone translates this.
Pywikibot (then "Pywikipediabot") was started back in 2002. In 2007 a new branch (formerly known as "rewrite", now called "core") was started from scratch using the MediaWiki API. The developers of Pywikibot have decided to stop supporting the compat version of Pywikibot due to bad performance and architectural errors that make it hard to update, compared to core. If you are using pywikibot compat it is likely your code will break due to upcoming MediaWiki API changes (e.g. T101524). It is highly recommended you migrate to the core framework. There is a migration guide, and please contact us if you have any problem.

There is an upcoming MediaWiki API breaking change that compat will not be updated for. If your bot's name is in this list, your bot will most likely break.

Thank you,
The Pywikibot development team, 19:30, 5 June 2015 (UTC)
