I think we should release 2.063.1, for these reasons:

- Regression bug 9122 is not actually fixed in 2.063 release although it's listed in fixed Phobos regressions

  Because current 2.063 release does not contain the fix for issue 10017.

  https://github.com/D-Programming-Language/phobos/commit/9a7627776e7cffa999f30e5a7450fb7f044a12f7

  Actually that was the root cause of 9122, so it should have been contained in 2.063 release.

- 2.063 release has some regressions which was discovered after releasing.

  Issue 10215 - [REG2.063] const causes wrong float calculation

    This is serious wrong-code bug. This bug does not exist in git master.

    To fix the bug, we just need to recreate release package.

    Read my comment:  http://d.puremagic.com/issues/show_bug.cgi?id=10215

  Issue 10212 - [REG2.061] Segfault in mismatching delegate literal types

    It's old regression bug, but should be fixed as soon as possible.

    Please review and merge https://github.com/D-Programming-Language/dmd/pull/2101

  Issue 10197 - [REG2.063] Cannot cast overloaded template property result

    Already fixed in git master.

From now I'll push some trivial changes to 2.063 branch which I think these are necessary for 2.063.1.

And I'll remove 2.063.1 tags for a moment. I think tagging should be done after the release done, but it's not yet released.
