Release 3.3.3

This is a production release with one tweak and fixes for manuals.

The tweak is that length(0) returns 1 instead of 0. In 3.3.1, I changed it so length(0.x), where x could be any number of digits, returned the scale, but length(0) still returned 0 because I believe that 0 has 0 significant digits.

After request of FreeBSD and considering the arguments of a mathematician, compatibility with other bc's, and the expectations of users, I decided to make the change.

The fixes for manuals fixed a bug where -- was rendered as -.

Release 3.3.0

This is a production release that changes one behavior and fixes documentation bugs.

The changed behavior is the treatment of -e and -f when given through BC_ENV_ARGS or DC_ENV_ARGS. Now bc and dc do not exit when those options (or their equivalents) are given through those environment variables. However, bc and dc still exit when they or their equivalents are given on the command-line.

Release 3.2.7

This is a production release that removes a small non-portable shell operation in configure.sh. This problem was only noticed on OpenBSD, not FreeBSD or Linux.

Non-OpenBSD users do NOT need to upgrade, although NetBSD users may also need to upgrade.

Release 3.2.6

This is a production release that fixes the build on FreeBSD.

There was a syntax error in configure.sh that the Linux shell did not catch, and FreeBSD depends on the existence of tests/all.sh.

All users that already upgraded to 3.2.5 should update to this release, with my apologies for the poor release of 3.2.5. Other users should skip 3.2.5 in favor of this version.

Release 3.2.5

This is a production release that fixes several bugs and adds a couple small things.

The two most important bugs were bugs that causes dc to access memory out-of-bounds (crash in debug builds). This was found by upgrading to afl++ from afl. Both were caused by a failure to distinguish between the same two cases.

Another bug was the failure to put all of the licenses in the LICENSE.md file.

Third, some warnings by scan-build were found and eliminated. This needed one big change: bc and dc now bail out as fast as possible on fatal errors instead of unwinding the stack.

Fourth, the pseudo-random number now attempts to seed itself with /dev/random if /dev/urandom fails.

Finally, this release has a few quality-of-life changes to the build system. The usage should not change at all; the only thing that changed was making sure the Makefile.in was written to rebuild properly when headers changed and to not rebuild when not necessary.
