Hi, I'm reading the PJSIP developer's guide (ver. 0.5.4) downloaded from the documentation section. Unfortunately, I found some mismatches with the latest pjproject version 1.1 (for example, in the pjsip_dialog structure definition I noticed new fields not documented in developer's guide). Is there any kind of document up to date? Is the developer's guide only a generic indication to the developers? Thanks.
