Bugfix

Fixed the crash of variable types collected. #4724
Fixed the crash in the optimization phase of multiple MATCH. #4780
Fixed the bug of aggregate expression type deduce. #4706

Fixed the bug of parameter expression in the LOOKUP statement. #4664
Fixed the bug that YIELD DISTINCT returned a distinct result set in the LOOKUP statement. #4651
Fixed the bug that ColumnExpression encode and decode are not matched. #4413
Fixed the bug that id($$) filter was incorrect in the GO statement. #4768
Fixed the bug that full scan of MATCH statement when there is a relational In predicate. #4748
Fixed the optimizer error of MATCH statement.#4771
Fixed wrong output when using pattern expression as the filter in MATCH statement. #4778
Fixed the bug that tag, edge, tag index and edge index display incorrectly. #4616

Fixed the bug that the return value of the date time vertex was changed. #4448
Fixed the bug that the startup service failed when the log directory not existed and enable_breakpad was enabled. #4623
Fixed the bug that after the metad stopped, the status remained online. #4610
Fixed the corruption of the log file. #4409
Fixed the bug that ENABLE_CCACHE option didn't work. #4648
Abandoned uppercase letters in full-text index names. #4628

Change

Vertices without tags are not supported by default. If you want to use the vertex without tags, add --graph_use_vertex_key=true to the configuration files (nebula-graphd.conf) of all Graph services in the cluster, add --use_vertex_key=true to the configuration files (nebula-storaged.conf) of all Storage services in the cluster. #4629
