incompatible

Nebula Graph v3.0.0 does not support the most ecosystem tools of v2.x, please upgrade the ecosystem tools.

The storage services added in the configuration files cannot be read or written directly. The configuration files only register the storage services into the meta services. You must run the ADD HOSTS command to read and write data on storage servers. #3343
Disable ZONE and GROUP. #3776 #3825 #3330

Add SHOW LOCAL SESSIONS and SHOW LOCAL QUERIES commands, and deprecate SHOW ALL QUERIES. #3488
A tag is not required for a vertex. DELETE VERTEX only deletes the vertices, and does not delete the related outgoing and incoming edges of the vertices. At this time, there will be dangling edges by default. #3316 #3335 #3328 #3286
Disable the YIELD clause to return custom variables. #3271
The YIELD clause is required in the FETCH, FIND PATH, LOOKUP, GET SUBGRAPH and GO statements. #3056 #3139 #2957
Add non-reserved keywords: s2_max_level, s2_max_cells. #3396
It is required to specify a tag to query properties of a vertex in a MATCH statement. For example, from return v.name to return v.player.name. #3255
