v1.0.0:

• Separate value caches and resource caches. The two distinct intended use
  are now given separate names and signatures. Resource caches are careful
  about resource ownership.

• Switch from First Class Module API to functor API.

• Note that this version is a complete rewrite with new package names, new
  module names, new APIs, new concepts. These changes are too numerous to be
  listed here: only the most important feature change is listed above. Refer
  to the README and the documentation which contain up-to-date information on
  the library as it stands.

• Compatible with OCaml 5.0.0. The previous version used functions of the
  Ephemeron module that were removed in OCaml version 5.

v0.9:

• Provide Collection.length

v0.8:

• Provide Collection.fold_older_first

• Documentation fixes

v0.7:

• Add filter to caches

• Support for empty and singleton caches in ringo-lwt

v0.6:

• Add specialised 0-sized and 1-sized caches

• Improved test coverage

• Improved documentation

v0.5:

• Fix leakiness of Lwt-wrapped caches (clean-up functions would hold onto bindings)

• Fix race condition in Lwt-wrapped caches (rejection of a non-held promise cannot cause removal of a held promise)

• Folding in Lwt-wrapped caches ignores failed promises (aligns semantics with automatic cleaning)

• Improve documentation of Lwt-wrapped caches

v0.4:

• Handle reinsertion as promotion

• bugfix: do not hard-fail when removing the single element of a collection

• Wrappers for Lwt, Lwt-Option, and Lwt-Result

• rename Strict to Strong (as opposed to Weak)

v0.3:

• Rename Loose as Weak

• Rename CACHE as CACHE_MAP (and associated name changes) to hint at key-value storage

• introduce set-caches (CACHE_SET) which are simple value caches (not key-value caches)

• introduce clear to empty caches entirely

• fix singleton-collection bug

• simplify code in main entry module

v0.2:

• complete rewrite: the library pivots towards caches

v0.1: Initial release
