  only on successful DDNS update (`compat` mode).  New `event` mode
  calls the script on any action, with added new environment variables.
- Cloudflare plugin, curated by Simon Pilkington:
  - Increased size of response buffer, JSON reply is quite big and
    In-a-dyn is used to one-liner replies from most servers

---------------------

### Changes
- Distribute `CONTRIBUTING.md` in release tarballs, by André Colomb

- Issue #179: Update easyDNS plugin to new API, by Nicholas Alipaz


[v2.2][] - 2017-08-09
---------------------

### Changes
- Use HTTP by default for DYN.com checkip server, used by many DDNS
  providers that do not have their own.  This change is far more user
  friendly since you no longer have to explicitly set `checkip-ssl =
  false` for the most common use-case.
- Some DDNS providers have multiple IP addresses registered for the same
  service, as of this release Inadyn immediately tries to connect to the
  next listed addresses on connection problems.
- Issue #153: Support for custom HTTP User Agent.  Useful with providers
  that require using a specific brower.  Set to, e.g. "Mozilla/4.0", or
  rely on the default "inadyn/VERSION" user agent.
- Support for the `%%` format specifier in custom server URL's, as
  mentioned in issue #152.
- Add support for a `.conf` syntax checker: `inadyn --check-config`
- Add support for logging to `stderr` when running in foreground or
  without syslog enabled
- Simplified provider name lookup in `.conf` file.  Now substring match
  is used, resulting in support for `provider Dyn { ... }`.
- Remove libite dependency by importing all its used files into inadyn.
  This should ease adoption by distributions and end users.  All code
  is under free licenses: BSD, ISC.
- Import Timur's Debian packaging, adding debconf support

### Fixes
- Issue #152: Do not attempt to create PID file in oneshot mode (`-1`)
- Issue #152: Must URL encode custom server URL's
- Issue #170: Use configured `--prefix` not hard coded `/etc/inadyn.conf`
- Issue #172: Use separate variable for `--iface` command line option and
  `.conf` file option


[v2.1][] - 2016-12-04
---------------------

### Changes
- Use HTTPS instead of HTTP by default
- Support for disabling HTTPS for `checkip-server`, per provider.
  Idea from Valery Frolov
- Add `-I,--ident=NAME` option for syslog+pidfile name
- Deprecate `--pidfile=NAME` option in favor of `--ident=NAME`

### Fixes
- Issue #150: Custom update URL parser fixes
- Issue #151: Support for detecting OpenSSL v1.1
- Issue #144: Clarify use of public vs private IP.  It is possible
  to register private IP addresses in a public DNS
- Clarify `--foreground` option in man page
- Document minimum required versions of libite and libConfuse
- Portability fixes, replace `__progname` with a small function,
  replace `%m` with `%s` and `strerror(errno)`.


[v2.0][] - 2016-09-12
---------------------

New configuration file format, changed command line options, improved
HTTPS support using GnuTLS and Open/LibreSSL.  Inadyn now comes with
certificate validation enabled by default.

### Changes
- New configuration file format using [libConfuse][]
- Radically simplified command line, a .conf file is now required
- Reorganized SSL code, split `ssl.c` into `openssl.c` and `gnutls.c`
- Strict HTTPS certificate validation is now default.  To disable this
  use `strict-ssl = false` in the .conf file.
- Certificate validation uses trusted CA certificates from the system
  with fall-backs to certain known locations.  To override this default
  handling a `ca-trust-file = FILE` setting in `inadyn.conf` can be used
  to provide the path to another CA cert bundle, in PEM format.
- Massive overhaul of `inadyn(8)` and `inadyn.conf(5)` man pages
- Support for reading address from interface, including IPv6 addresses
- Support for calling an external script to get the IP address
- Support for multiple users @ same provider, idea from Valery Frolov:

        provider default@no-ip.com:1 {
            username    = ian
            password    = secret
            alias       = flemming.no-ip.com
        }
    
        provider default@no-ip.com:2 {
            username    = james
            password    = bond
            alias       = spectre.no-ip.com
        }

- Support for ddnss.de and dynv6.com, contributed by Sven Hoefer
- Support for spdyn.de, on request from Frank Röhm
- Support for strato.com, contributed by Duncan Overbruck
- Support for disabling IP address validation: `verify-address = false`
- Refactored memory handling and privilige separation to simplify code
- Refactored logging and backgrounding to simplify code
- Removed old compatibility symlinks and other required GNU specific
  files, we now distribute and install README.md and ChangeLog.md

### Fixes

- Fix issue #67: Use GnuTLS native API for HTTPS

- Fix issue #113: `--drop-privs` does not work
- Add actual permissions check to `os_check_perms()`
- Fix issue #121: Support for fully customizable update URL
- Fix issue #122: Only use HTTPS connection for DNS update, not checkip
- Fix issue #131: Use FreeDNS' own checkip server instead of DYN.com's
- Fix issue #134: Support wildcard cert with GnuTLS backend


[1.99.15][] - 2015-09-09
------------------------

Minor bugfix release.

### Changes
- Support for new API at https://tunnelbroker.net, fixes issue #83.
  Use `default@tunnelbroker.net` to use the DYN.com API to update
  the IPv4 address for your IPv6-in-IPv4 tunnel.  Thanks goes to
  Horst Venzke @hvenzke for reporting this problem!
- The old API for the IPv6-in-IPv4 system `ipv6tb@he.net` is now
  deprecated.  Users should migrate to `default@tunnelbroker.net`
- Files generated by the GNU Configure & Build System is now no longer
  stored in GIT.  Instead, users that rely on GIT must run the new
  `./autogen.sh` script to generate the necessary files (`configure`).


### Fixes
- Fix issue #100: regression from [1.99.13][] pidfile is no longer
  created.  Inadyn 1.x semantics incompatible with OpenBSD `pidfile()`
  that replaced local version in [1.99.14][].  Problem found by David
  Schury @daersc.
- Fix issue #107: If an IP address update fails, e.g. due to temporary
  connectivity, HTTP transmission problems, etc. then Inadyn now forces
  an update in the next IP check cycle.  (This is the configurable
  `period` interval in `inadyn.conf`.)  Reported by Oliver Graute
  @redbrain17 and audited by @BulldozerBSG, thanks!
- Fix issue #108: Update README with correct alias syntax for Namecheap,
  issue reported by @quazar0


[1.99.14][] - 2015-07-14
------------------------

Improved support for configuring custom DDNS providers and support for
running in Windows, using Cygwin!

### Changes
- New setting `append-myip` which, instead of appending your hostname
  alias, appends the current IP to the server GET update URL.  See
  [README][README.md] or the man pages for more details.
- Prevent Inadyn from bugging out if it cannot write a cache file when
  the `-o, --once` flag is given.
- Inadyn now defaults to a silent build, use V=1 (like Linux) to get a
  verbose build.  Useful for auto-builders etc.
- Migrate to [libite][] for functions like `pidfile()`, `strlcpy()` etc.
- Add support for <http://GiraDNS.com>, thanks to Thorsten Mühlfelder!
- Add support for <https://www.duiadns.net>, thanks to Ionut Slaveanu!

### Changes
- Merge wl500g patches from <http://code.google.com/p/wl500g>:
  - `101-http-request.patch`. This cleans up the DDNS server defintions
	and callbacks, evidently originating from ideas implemented by
	DD-WRT.
  - `102-zoneedit.patch`. This fixes issues in what appears to be both
	request and response formats in ZoneEdit DDNS. Originating from
	DD-WRT.
  - `103-tzo.patch`. This patch adds support for tzo.com DDNS serivices.
  - `110-dnsomatic.patch`.  This patch adds support for DNS-O-Matic
	<http://dnsomatic.com/>, an OpenDNS service which can act as a
	"meta" update to several other DDNS service providers.
  - `120-heipv6tb.patch`. This patch adds support for Hurricane Electric's
	http://tunnelbroker.net/ DDNS services <https://dns.he.net/>.
- When starting: always use cache file, if it exists, or seed with DNS
  lookup

  immediately after first update, not after the sleep period as before

  "Copy-paste" error :-(
