Bugs fixed in this release:

• A stale Tcl_Obj could lead to a hang or crash when sending SNMP requests with varbinds that include syntax, where the syntax (as provided) is a non-base type.
• Querying properties on an object using a symbolic name plus subidentifier, when the object has variations defined, could lead to an infinite loop.
• A crash could occur on exit when database or session commands were invoked in a callback called after the exit started, such as in the handler for a toplevel window.
