Bug fixes
Fix vulnerability in OAuth where user-submitted authorization token was used for authentication
(https://github.com/buildbot/buildbot/wiki/OAuth-vulnerability-in-using-submitted-authorization-token-for-authentication). Thanks to Phillip Kuhrt for reporting it.
v2.3.0
Highlights
Support for older browsers has been hopefully temporarily broken due to frontend changes in progress. Notably, Internet Explorer 11 is not supported in this release. Currently supported browsers are Chrome 56, Firefox 52, Edge 13 and Safari 10, newer versions of these browsers and their compatible derivatives. This set of browsers covers 98% of users of buildbot.net.
Bug fixes

Deprecations and Removals
The implementation language of the Buildbot web frontend has been changed from CoffeeScript to JavaScript. The documentation has not been updated yet, as we plan to transition to TypeScript. In the transitory period support for some browsers, notably IE 11 has been dropped. We hope to bring support for older browsers back once the transitory period is over.

Deprecations and Removals
Removed support for Python 2.7 in the buildbot master code.

APIs that are not documented in the official Buildbot documentation have been
made private. Users of these undocumented APIs are encouraged to file bugs to
get them exposed.
Removed support of old slave APIs from pre-0.9 days. Using old APIs may fail
silently. To avoid weird errors when upgrading a Buildbot installation that
may use old APIs, first upgrade to to 1.8.0 and make sure there are no
deprecated API warnings.
Remove deprecated default value handling of the keypair_name and
security_name attributes of EC2LatentWorker.
