## 0.14

- add `Tiny_httpd_io` module, abstraction over IOs (output/input) as better IO channels
    than the stdlib's

- add `Server.run_exn`
- add `Tiny_httpd_pool`
- server: add `IO_BACKEND` abstraction; implement a unix version of it

## 0.13

- feat: `Server.run` takes `?after_init` parameter
- remove dep on ounit2 and qtest
- expose `Response.make_void`
- Add OPTIONS method
- use ocamlformat on the code

## 0.12

- add dep on `seq`
- add a `Html` module with combinators to produce html
- add `Tiny_httpd_dir.VFS` to emulate file systems
- add a small program, `tiny-httpd-vfs-pack`, to pack directories and files
  (local or behind a URL) into a OCaml module using `VFS`
- show small example of socket activation

## 0.11

- breaking: remove deprecated path handlers based on scanf
- breaking: more getter/setters for request/response, change signatures,
  make request/response private aliases

- fix: release semaphore in case of exception in accept

- feat: add a notion of Middleware
- feat: add `?middlewares` param to `create`
- feat: add `?get_time_s` param to `create`
- feat: close connection if response's headers contains connection
- feat: store `start_time` in request
- feat: implement connection timeout using socket options
  Default is `max_keep_alive = -1.0` which preserves the original behaviour.
- feat: in server-sent-events, add a `close()` function

- refactor(zip): compression is now a middleware
- perf: pass `buf_size` in many places, set default `buf_size` to 16kb
- example: update `echo` to provide a /stats/ endpoint using a middleware

## 0.10

- feat: allow socket activation by passing a raw unix socket to `create`
- fix: `Unix.accept` may raise an exception
  (typicall Unix.EINTR, even with sigpipe blocked ?),
