Pascal Martin has posted his latest summary of the discussions happening on the php.internals mailing list for the month of October 2014.

809 messages have been exchanged in October 2014 on PHP’s internals@ mailing-list — a bit more than in September. [...] First of all, PHP 5.6 has entered its normal cycle of releases, with a first maintenance version at the beginning of the month.

He includes a graph of the (monthly) number of emails over the last year and how October fits in. Topics mentioned include:

• an RFC to remove deprecated functionality in PHP7
• the RFC for the PHP7 release timeline
• Flagging functions as deprecated in favor of variadic functions
• Getting the XML output of a phpdbg tool closer to the DBGp protocol
• an RFC for big integer support
• an proposal for allowing objects as hash keys
