Release 0.12.0

@ronkok here:

… #2219, which was fixed by PR #2220 in March. The problem is that we have not had a release issued since September. There are also some bug fix PRs waiting for review, much less release.

We should review at least the bug-fix PRs, and then do a release. (Sorry, I’ve been slacking on this as much as everyone.) @ronkok, can you list which PRs you think are important and/or easy for review before release, so we can prioritize? I’ll then make a list here that can track progress:

Bug fixes:

• PR #2234, Fix a parenthesis rendering bug — awaiting responses/revisions
• PR #2278, Prevent a crash when \substack has no argument.
• PR #1841, Remove space after \\
• PR #2290, Fix \boldsymbol{\Omega}
• PR #2236, Fix fraction bar color
• PR #2295, Fix website trust
• PR #2156, Font cleanup, fix \i spacing

PRs that aim at making the documentation more clear or complete:

• PR #2269
• PR #2279
• PR #2280 — ~~blocked on https://github.com/bradhowes/remarkable-katex/issues/4~~
• PR #2289
• PR #2297

@edemaine I think it’d be safe to do with the current environment. I’ll prepare a release PR.

I can do it. Another concern is #2082, which may cause security issues. I think its documentation may be insufficient.
