Version 2.4.0

This is a production release primarily aimed at improving dc.

• A couple of copy and paste errors in the dc manual were fixed.
• dc startup was optimized by making sure it didn't have to set up bc-only things.
• The bc && and || were made available to dc through the M and m commands, respectively.
• dc macros were changed to be tail call-optimized.

The last item, tail call optimization, means that if the last thing in a macro is a call to another macro, then the old macro is popped before executing the new macro. This change was made to stop dc from consuming more and more memory as macros are executed in a loop.

The q and Q commands still respect the "hidden" macros by way of recording how many macros were removed by tail call optimization.

Version 2.3.1

This is a production release. It fixes a bug that caused -1000000000 < -1 to return 0. This only happened with negative numbers and only if the value on the left was more negative by a certain amount.

ALL USERS SHOULD UPDATE bc.

This release contains a fix for the test suite made for Linux from Scratch: now the test suite prints pass when a test is passed.

Other than that, there is no change in this release, so distros and other users do not need to upgrade.
