I've brought neo4cl up to date with Bolt 4.3, and I'd like to implement support for 5.0 while I'm on a roll.
The compatibility page indicates that there's a 5.0 version of the protocol, but I don't see any mention of it in the protocol specs. Are there updates in progress for this?
Hello, I think it's missing from the docs indeed, we'll fix this ASAP.
In Bolt 5.0 (Neo4j server 5.0 to 5.4 included), the only noteworthy change is that UTC-based DateTime structures have completely replaced the legacy ones (in 4.4, the UTC-based structures have to be negotiated with the server): A Timely Update to the Bolt Protocol - Neo4j Graph Data Platform
In Bolt 5.1 (starting with Neo4j server 5.5), LOGON and LOGOFF messages have appeared. They should be added to the documentation fairly soon.
