## [4.3.1] - 2020-07-08

   See !44 and !42.

## [4.3.0] - 2020-04-22

- `SLIRP_VERSION_STRING` macro, with the git sha suffix when building from git
 - `SlirpConfig.disable_dns`, to disable DNS redirection #16

### Changed

- `slirp_version_string()` now has the git sha suffix when building form git
 - Limit DNS redirection to port 53 #16

### Fixed

 - Fix use-afte-free in `ip_reass()` (CVE-2020-1983)

## [4.2.0] - 2020-03-17

### Added

- New API function `slirp_add_unix`: add a forward rule to a Unix socket.
 - New API function `slirp_remove_guestfwd`: remove a forward rule previously
   added by `slirp_add_exec`, `slirp_add_unix` or `slirp_add_guestfwd`
 - New `SlirpConfig.outbound_addr{,6}` fields to bind output socket to a
   specific address

### Changed

- socket: do not fallback on host loopback if `get_dns_addr()` failed
   or the address is in slirp network

### Fixed

- ncsi: fix checksum OOB memory access

## [4.1.0] - 2019-12-02

### Added

- The `slirp_new()` API, simpler and more extensible than `slirp_init()`.
 - Allow custom MTU configuration.
 - Option to disable host loopback connections.
 - CI now runs scan-build too.

### Changed

- Disable `tcp_emu()` by default. `tcp_emu()` is known to have caused
   several CVEs, and not useful today in most cases. The feature can
   be still enabled by setting `SlirpConfig.enable_emu` to true.
 - meson build system is now `subproject()` friendly.
 - Replace remaining `malloc()`/`free()` with glib (which aborts on OOM)
 - Various code cleanups.

### Deprecated

- The `slirp_init()` API.

### Fixed

- `getpeername()` error after `shutdown(SHUT_WR)`.
 - Exec forward: correctly parse command lines that contain spaces.
 - Allow 0.0.0.0 destination address.
 - Make host receive broadcast packets.
 - Various memory related fixes (heap overflow, leaks, NULL
   dereference).
 - Compilation warnings, dead code.

## [4.0.0] - 2019-05-24

### Added

- Installable as a shared library.
 - meson build system
   (& make build system for in-tree QEMU integration)

### Changed

- Standalone project, removing any QEMU dependency.
 - License clarifications.
