Time for a new release?

[MiguelCompany]

Since the last release, there have been some changes.
I am particularly interested in #139 and #147.

@foonathan Do you think it's time for a new release?

I agree, especially with the bugs reported in the last couple of weeks. I've tagged a new release: https://github.com/foonathan/memory/releases/tag/v0.7-3
