2.2.0

This release replaces the dependency on Core with Base, greatly reducing the number of transitive dependencies. Base is small enough and only relies on ppx_sexp_conv, making Tdigest acceptable to non-Core users.

2.1.3

Added the Tdigest.Marshallable module.

2.1.2

Adds support for Core v0.16.0

2.1.1

• Optimized t_of_sexp/sexp_of_t, they now use the dense string representation of of_string/to_string
• Added validation to add and add_list: the ?n parameter cannot be <= 0

2.1.0

• Added Tdigest.is_empty
• Added [@@deriving sexp] to all visible data types.
  • Note: it's strongly recommended to serialize/deserialize using to_string/of_string instead of the S-Expression functions
    • This has been fixed in 2.1.1
• Further optimized to_string, of_string, and a few internal systems

2.0.0

Release for Core v15, otherwise identical to 1.0.0
