= Discussion =
* Chimera 1.12 waiting on:
  - turning off virus-checking does not solve "cannot rename file" issue, still waiting for info on turning off Windows indexing
  - ~~openssl on Linux~~, use ChimeraX approach of adding root certificate file from known system locations
  - ~~splash screen problem with PIL fixed
  - Put candidate release up now (Greg will handle branching and release notes migration, Conrad will go through svn logs for notable bug fixes)
* Chimera issues
  - RCSB wants us to use https to wwpdb.org to fetch files
* Alpha 3
  - Sessions: msgpack vs pickle
    - Use different extension mechanism to handle tuples/lists instead of overloading map serialization and checking for special  {{{ __type__ }}} key
    - Other custom types, e.g., DateTime, will use new extension mechanism as well
    - Python version is done but very slow
    - Working on C version for speed
* Alpha 4
  - Undo manager
    * Conrad
    * getting closer
  - Preferences GUI
    * Eric
    * Core preferences + 1 example bundle preferences
    * Ensure fetching URL is settable via preferences
  - Zone atomspec
    * Conrad
    * chains still need work, only selects polymer
  - Rescan tickets, in particular, findclash
* Beta release topics
  - Why do we need a beta so soon?  Why not leave it as alpha?
  - Is December a realistic target?
  - Will bundles move out from core, e.g., atomic?
  - What are the beta APIs?  Toolshed.  Atomic.  Command...
  - How much "firming up" API is needed?
  - What consists of "the API"?  Public methods, even those without Sphinx documentation?
  - Release protocol for "core" bundles?

= Action Items =
* Conrad will continue working on ribbon tickets
* Conrad will investigate implementing the "like" operator
 - e.g., to specify polymer in atomspec
* Scooter will investigate making tickets public (possibly marking some tickets private)
* Conrad will send mail to RCSB about bad pdb.org certificate
* Greg will handle Chimera 1.12 branching and release notes migration
* Conrad will go through Chimera 1.12 svn logs for notable bug fixes
