1.3.1

• Revise breakpoint handling; Breakpoints now use code objects, not (possibly ambiguous) function names
• Fix bugs in detecting when stopped at a def and in nextlineno()
• Better information when current frame is inside a builtin eval or exec call
• Fix some of the many disasm spec problems.
• Go over eval, skip, step, jump, and autoeval documentation
• Guard against invalid frame indexing in backtrace
• Suggest import when a function is not found in getting a location
• Improve "info frame", for example, opcode, add opcode source line
• Allow breakpoints in a not-frozen module
• Improve print_location() handling via deparsing (in older Python versions)
• Tolerate missing keys in settings lookup.
• Temporary file name is now based on some of the deparsed text (when we can deparse)
