+## v0.3 _(2023-02-03)_
+
+### Added
+- **(breaking change)** add a datatype `Backends.QueuingFlag` to set the queuing
+  mode
   - the `initSolver` function now takes this datatype as argument instead of a
     boolean
+- **(breaking change)** add a `send_` method to the `Backends.Backend` datatype
+  for sending commands with no output
+- add a `Backends.flushQueue` function for forcing the content of the queue to
+  be evaluated
+
+### Changed
 - **(breaking change)** make the queuing functions thread-unsafe but faster
-- add a `send_` method to the `Backends.Backend` datatype for sending commands with no output
-- add a `Backends.flushQueue` function for forcing the content of the queue to be
-  evaluated
 
-# v0.2
+## v0.2 _(2022-12-16)_
+
+### Changed
 - split the `Process` module into its own library
 - rename `SMTLIB.Backends`'s `ackCommand` to `command_`
+- improve read-me
+
+### Removed
 - remove logging abilities
   - the user can always surround `command` or `command_` with their own logging
     functions

 ## Building and testing
 
 This repository provides a reproducible build environment through a [Nix
 flake](https://www.tweag.io/blog/2020-05-25-flakes/).

 ## Implementing backends
 
 Currently, backends only need to provide a function to submit queries, as
 documented in [SMTLIB.Backends.Backend](src/SMTLIB/Backends.hs). See
-[SMTLIB.Backends.Process.toBackend](smtlib-backends-process/src/SMTLIB/Backends/Process.hs) or
-[SMTLIB.Backends.Z3.toBackend](smtlib-backends-z3/src/SMTLIB/Backends/Z3.hs) for examples.

+for examples.
 
 ## Motivation
 
-This library was created because there are a lot of Haskell projects using SMT solvers
-through SMT-LIB, but most of them only use solvers through external processes
-and implement the interaction with the solver themselves. But running solvers
-as external processes can be quite slow, hence this library aims to provide
-other, more efficient ways to do so. We believe having one well-optimized and
-safe library is more efficient than having the same code be spread out between
-different projects.

+## v0.3 _(2023-02-03)_
+
+### Added
 - add tests for documenting edge cases of the backends
   - check that we can pile up procedures for exiting a process
   - what happens when sending an empty command
   - what happens when sending a command not producing any output
-- add `Process.defaultConfig`, synonym for `def`
-- improve error messages inside `Process.toBackend`
+- add `Process.defaultConfig`
+- add `std_err` field in `Config`: the user may now specifiy how to create the
+  handle for the error channel
+
+### Changed
+- make the test-suite compatible with `smtlib-backends-0.3`
 - **(breaking change)** use `process` instead of `typed-process` to manage the underlying process
   - change the definition of the `Process.Handle` datatype accordingly
   - remove `Process.wait`
   - there is now a single example in the test-suite showing how to 
     manage the underlying process and its I/O channels
+- improve error messages inside `Process.toBackend`

+### Removed
+- removed `Process.wait`
