Set master version to 1.5

[ararslan]

VERSION has been set to 1.5.0-DEV, the 1.4 NEWS items have been moved to HISTORY, and NEWS has been cleared out for 1.5 items.

Please don't merge anything to master until this is merged so that versions don't get messed up, since 1.4 has been branched.

[JeffBezanson]

NEWS needs edits. I'll do a pass.

Please don't merge anything to master until this is merged so that versions don't get messed up, since 1.4 has been branched.

For future releases, can we just merge this to master whenever and the create the release branch from whatever the commit before was? Trying to lock master without an enforcement mechanism seems potentially problematic.

[ararslan]

Yes, agreed.

I'm getting

at the end of trying to build Julia. Related? Easy fix?

[ararslan]

Very weird, I have not gotten that on any of my systems: I've rebuilt from source with this change on Linux, macOS, and FreeBSD. Perhaps clean it out (git clean -fdx is what I do) and try again?

[timholy]

Worked, thanks! (Note for anyone who reads this: first save elsewhere any untracked files you don't want deleted.)

[ararslan]

make distclean-all (or whatever it's called) might work as well and wouldn't delete your stuff.

[vtjnash]

rm -rf usr almost always works too, and is quick

[ViralBShah]

That would not remove the .o files right? We have too many (4) clean targets. Max level is distcleanall.
