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.

Release 3.2.0

This is a production release that has one bug fix and a major addition.

The bug fix was a missing auto variable in the bessel j() function in the math library.

The major addition is a way to build a version of bc's math code as a library. This is done with the -a option to configure.sh. The API for the library can be read in ./manuals/bcl.3.md or man bcl once the library is installed with make install.

This library was requested by developers before I even finished version 1.0, but I could not figure out how to do it until now.

If the library has API breaking changes, the major version of bc will be incremented.

Release 3.1.4

This is a production release that fixes one bug, changes two behaviors, and removes one environment variable.

The bug is like the one in the last release except it applies if files are being executed. I also made the fix more general.

The behavior that was changed is that bc now exits when given -e, -f, --expression or --file. However, if the last one of those is -f- (using stdin as the file), bc does not exit. If -f- exists and is not the last of the -e and -f options (and equivalents), bc gives a fatal error and exits.

Next, I removed the BC_EXPR_EXIT and DC_EXPR_EXIT environment variables since their use is not needed with the behavior change.

Finally, I made it so bc does not print the header, though the -q and --quiet options were kept for compatibility with GNU bc.
