 /**
- * Version above which we use the CLI's indirect build tracing and
- * multi-language tracing features.
+ * This variable controls using the new style of tracing from the CodeQL
+ * CLI. In particular, with versions above this we will use both indirect
+ * tracing, and multi-language tracing together with database clusters.
  *
- * There are currently three blockers on the CLI's side to enabling this:
- * (1) The logs directory should be created for a DB cluster, as some
- *     autobuilders expect it to be present.
- * (2) The SEMMLE_PRELOAD_libtrace{32,64}? env variables need to be set.
- * (3) The .environment and .win32env files need to be created next to
- *     the DB spec.
- *
- * Once _all_ of these are fixed, we can enable this by setting the
- * version flag below to the earliest version of the CLI that resolved
- * the above issues.
+ * Note that there were bugs in both of these features that were fixed in
+ * release 2.7.0 of the CodeQL CLI, therefore this flag is only enabled for
+ * versions above that.
