# Revision history for `resolv`

## 0.2.0.0

_2023-03-31, Alexey Radkov and Andreas Abel_

* Bump `bytestring` to `>= 0.10` for correct `IsString ByteString` instance.
  (PR [#16](https://github.com/haskell-hvr/resolv/pull/16).)
* Fix memory leaks due to missing `res_nclose()` after each `res_ninit()` call.
  (PR [#12](https://github.com/haskell-hvr/resolv/pull/12).)
* Check the value of `h_errno` on failures of `res_nquery()` and throw an
  appropriate exception of type `DnsException` built with one of new
  constructors `DnsHostNotFound`, `DnsNoData`, `DnsNoRecovery`, or `DnsTryAgain`.
  Note that previously such exceptions were thrown by `fail` and had type `IOError`.
  (PR [#17](https://github.com/haskell-hvr/resolv/pull/17).)
* Suppress configure warning on option `--with-compiler` passed by Cabal.
  (PR [#21](https://github.com/haskell-hvr/resolv/pull/21).)
* Tested with GHC 8.0 - 9.6.
