+0.3.3 (2018-09-06)
+------------------
+
+This release contains a breaking change for hsv setter, which is changed to accept
+the new brightness value in percentage instead of an integer between 1 and 255.
+
+The alias support has been extended to allow changing the alias, as well as accessing
+the device using it (without specifying an IP address or a hostname), which can be
+useful in some setups. Furthermore utf8-encoded aliases are now handled correctly.
+
+- Fix bug that changed brightness at each HSV update (#124) [Sebastian Templ]
+
+  * Fix bug that changed brightness at each hsv update
+
+  The HSV setter should accept a percentage for the brightness
+  value but actually assumed the brightness to be in absolute values
+  between 1 and 255.
+  This resulted in brightness reductions at each HSV update, in
+  steps of 100% -> 100/255=39% -> 39/255=15% -> ... (see also
+  https://github.com/home-assistant/home-assistant/issues/15582,
+  where I originally reported this bug).
+
+  * Modify HSV property to return brightness in percent
+
+  Switch from reported brightness values of 1..255 to percentage
+  values, for consistency with the apidoc and 8761dd8.
+
+  * Add checks and tests for the hsv setter
+
+  - make sure that new (hue, saturation, brightness) values are
+    within their valid ranges (0..255, 0..100, 0..100) and raise
+    SmartDeviceException if they are not
+  - add test function for the hsv setter
+
+- Allow using alias instead of IP address or hostname (#127) [kwazel]
+
+  * Added option to control devices by device name
+
+  * set unused ip address to dont-care
+
+  * spend less time discovering by devicename, removed command
+
+  * consistent use of alias instead of device name
+
+  * processed review comments
+
+  * Return when no device with alias has been found
+
+- Add 'alias' command for querying and setting the alias (#126) [Teemu R]
+
+  * add 'alias' command for querying and setting the alias
+
+  * calculate coverage only on library files, e.g., ignoring cli and test files
+
+  * remove py34 and add py37
+
+  * readd py33, remove it from travis as it seems to be a travis limitation only
+
+  * use xenial dist for travis, regular does not support py37..
+
+- Support Unicode strings in encrypt/decrypt (#125) [Anders Melchiorsen]
+
+
+0.3.2 (2018-06-17)
+------------------
+
+- Add bulb valid temperature range (#122) [Thibault Cohen]
+
+
+0.3.1 (2018-06-16)
+------------------
+
+This release adds a few improvements, most importantly:
+
+* emeter support for new HS110 hardware/firmware revision.
+
+* HS220 supports now dimming.
+
+Breaking changes:
+
+* get_emeter_daily & get_emeter_monthly will report back in kwh on bulbs, making the API consistent with the smart plugs.
+
+- Fix emeter support for newer HS110 firmwares (#107) [Teemu R]
+
+  * Add support for new-style emeter
+
+  This commit adds a straightforward dict-extending container,
+  which converts between the old and new keys of the get_emeter_realtime()
+  Furthermore the unit tests are converted to base on HS100
+  instead of HS110.
+
+  This is the first step to fix #103, other emeter-using functionality
+  has not yet been converted, only getting the current consumption.
+
+  * fix a couple of linting issues
+
+  * Convert new-style emeter values also for get_emeter_daily() and get_emeter_monthly()
+
+  * Adds a new 'kwh' parameter for those calls, which defaults to True
+  * This changes the behavior of bulbs emeter reporting, use False if you prefer the preciser values
+
+- Update pypi description (#102) [Teemu R]
+
+  * update pypi description
+
+  * add wall switches
+
+- Update smartplug.py to support dimming in HS220 (#115) [JsChiSurf]
+
+  * Update smartplug.py to support dimming in HS220
+
+  Switch functions essentially as a "plug" with the addition to support for dimming, for which can be test for by verifying existence of
+'brightness' array value.
+
+  * Attempt at updates to pass validator
+
+  * Maybe this time?  :-)
+
+  * Add more detail to comment blocks
+
+  Make clear in requests for current brightness level the expected return values, and note that light will turn on when setting a brightness
+level, if not already on.  This makes clear that a state change request (turn_on) does NOT have to be made first when setting brightness.
+
+  * Update smartplug.py
+
+  * Update smartplug.py
+
+  Fixes #114
+
+- Add python_requires for >= 3.4. [Teemu Rytilahti]
+
+- Add hs210. [Teemu R]
+
+  Based on user report: https://community.home-assistant.io/t/tp-link-hs210-3-way-kit/39762/6
+
+- Add support for DNS host names (#104) [K Henriksson]
+
+- Use direct device type discovery for devices (#106) [K Henriksson]
+
+  This is more efficient than enumerating all devices and checking the IP.
+
+- Cli: add 'time' command to get the current time from the device.
+  [Teemu Rytilahti]
+
+- Created a docker file to aid dev setup (#99) [TheSmokingGnu]
+
+  * created a docker file to aid dev setup
+
+  * fixed review comments in README and Dockerfile
+
+  * review comments to simplify the docker run command
+
+
+0.3.0 (2017-09-14)
+------------------
+
+This is the first release after a while and aims to improve the robustness all-around.
+To make this happen we have decided to break the API and drop the support for Python 2.
+
+API break:
+    * Python2 support has been dropped.
+    * pyHS100/pyHS100.py has been splitted to smartdevice.py, smartplug.py and smartbulb.py, no one should have ever accessed these directly though.
+    * SmartPlugException is no more, SmartDeviceException is used by both SmartPlug and SmartBulb
+    * Discovery has been moved from TPLinkSmartHomeProtocol into its own class for easier 3rd party use.
+    * SmartDevice's identify() and `features` will emit a warning when used. These will likely be dropped or revised in the future and their use should be avoided.
+
+Other changes:
+
+    * CLI tool supports device discovery and is usable without specifying device type or IP for testing
+    * CLI tool supports changing bulb-specific settings
+    * Library support & unit tests are extended to cover more devices.
+       - Supported plugs: HS100, HS105, HS110
+       - Supported switches: HS200
+       - Supported bulbs: LB100, LB110, LB120, LB130

+
+  * Check for mic_mac on mac, based on work by kdschloesser on issue #59
+
+  * make hound happy, __init__ on SmartDevice cannot error out so removing 'raises' documentation

+
+  * Add .gitignore for posterity
+
+- Generalize smartdevice class and add bulb support for the cli tool (#50) [Teemu R]
+
+  Fixes #48 and #51. The basic functionality should work on all types of supported devices, for bulb specific commands it is currently necessary to specify ```--bulb```.
+
+- Refactor and drop py2 support (#49) [Teemu R]
+
+  * move is_off property to SmartDevice, implement is_on for bulb and use it

+0.2.4.2 (2017-04-08)
+--------------------
+- Add installation requirement for future package. [Teemu Rytilahti]
+
+0.2.4.1 (2017-03-26)
+--------------------
+- Cli: display an error if no ip is given. [Teemu Rytilahti]
+
+
+0.2.4 (2017-03-26)
+------------------
+
+- Add new client tool (#42) [Teemu R]
+
+  * Add new client tool
+
+  After installing the package pyhs100 command-line tool can be used
+  to control the plug.
+
+  See --help for its usage, most of the features for plugs are implemented,
+  some of the shared functionality works for bulbs too.
+
+  * Add discover command
+
+  * Delete old examples, the cli works as an example well enough
+
+- Ignore OSError on socket.shutdown() [Teemu Rytilahti]
+
+  This fixes #22 and obsoletes PR #23.
+- Set color temp to 0 when trying to change color (#36) [pete1450]
+
+  * set color temp to 0 when trying to change color
+
+  * changed tabs to spaces
+
+- Add changelog & add .gitchangelog.rc (#28) [Teemu R]
+
+  This commits adds .gitchangelog.rc for changelog generation.
+  To generate, simply run gitchangelog.
+
+- Discover: Catch socket.timeout and debug log it (#34) [Teemu R]
+
+  Fixes #33
+
+- Add flake8 to tox, disable qa on pyHS100/__init__.py, fix py27
+  compatibility (#31) [Teemu R]
+
+- Add support for TP-Link smartbulbs (#30) [Matthew Garrett]
+
+  * Add support for new-style protocol
+
+  Newer devices (including my LB130) seem to include the request length in
+  the previously empty message header, and ignore requests that lack it. They
+  also don't send an empty packet as the final part of a response, which can
+  lead to hangs. Add support for this, with luck not breaking existing devices
+  in the process.
+
+  * Fix tests
+
+  We now include the request length in the encrypted packet header, so strip
+  the header rather than assuming that it's just zeroes.
+
+  * Create a SmartDevice parent class
+
+  Add a generic SmartDevice class that SmartPlug can inherit from, in
+  preparation for adding support for other device types.
+
+  * Add support for TP-Link smartbulbs
+
+  These bulbs use the same protocol as the smart plugs, but have additional
+  commands for controlling bulb-specific features. In addition, the bulbs
+  have their emeter under a different target and return responses that
+  include the energy unit in the key names.
+
+  * Add tests for bulbs
+
+  Not entirely comprehensive, but has pretty much the same level of testing
+  as plugs
+
+
+0.2.3 (2017-01-11)
+------------------
+
+- Add .gitchnagelog.rc for changelog generation. to generate, simply
+  install and run gitchangelog. [Teemu Rytilahti]
+
+- Version bump. [GadgetReactor]
+
+- Initial steps to remove caching (#26) [Teemu R]
+
+  This commit removes caching of sysinfo to avoid
+  inconsistent states as described in issue #14.
+
+  Each an every access for properties will cause a request
+  to be made to the device. To avoid this, user of the library
+  may want to access sys_info() directly instead of using the helpers.
+
+  Currently sys_info() returns raw json object where-as helpers do
+  parse information for easier consumption; current state is just to
+  provide a PoC how it looks compared to having an active update()
+  for fetching the info.
+
+- Make tests runnable without device (#24) [Teemu R]
+
+  * Make tests runnable without device
+
+  Adds preliminary support for fake devices, thanks to
+  hoveeman's sysinfos from issue #14,
+  making running tests possible without a device.
+
+  At the moment we have only HS110 and HS200 infos available, and tests
+  are currently run only against HS110 data.
+
+  * Make tests py27 compatible
+
+- Add device discovery (#25) [Teemu R]
+
+  * add (untested) discover mode
+
+  * Keep discovery and normal communication separate, uppercase magic consts
+
+  This sepearates the earlier test code for discovering devices,
+  and adds 5 sec timeout for gathering responses from potential devices.
+
+  This commit also uppercases magic constants.
+
+  Discovery & communication tested with HS110.
+
+  * update readme with example how to discover devices, pep8ify
+
+- Add timeout to query (#19) [Austin]
+
+- Refactor & add unittests for almost all functionality, add tox for
+  running tests on py27 and py35 (#17) [Teemu R]
+
+  * Refactor & add unittests for almost all functionality, add tox for running tests on py27 and py35
+
+  This commit adds unit tests for current api functionality.
+  - currently no mocking, all tests are run on the device.
+  - the library is now compatible with python 2.7 and python 3.5, use tox for tests
+  - schema checks are done with voluptuous
+
+  refactoring:
+  - protocol is separated into its own file, smartplug adapted to receive protocol worker as parameter.
+  - cleaned up the initialization routine, initialization is done on use, not on creation of smartplug
+  - added model and features properties, identity kept for backwards compatibility
+  - no more storing of local variables outside _sys_info, paves a way to handle state changes sanely (without complete reinitialization)
+
+  * Fix CI warnings, remove unused leftover code
+
+  * Rename _initialize to _fetch_sysinfo, as that's what it does.
+
+  * examples.cli: fix identify call, prettyprint sysinfo, update readme which had false format for led setting
+
+  * Add tox-travis for automated testing.
+
+0.2.2 (2016-12-13)
+------------------
+
+- Version bump (#16) [Georgi Kirichkov]
+
+- Read all data from the device, disable double-encoding, implement more
+  APIs, refactor querying, update README (#11) [Teemu R]
+
+  * Read from socket until no data available, disable double string encoding
+
+  HS110 sends sometimes datagrams in chunks especially for get_daystat,
+  this patch makes it to read until there is no more data to be read.
+
+  As json.dumps() does JSON encoding already, there's no need to str()
+  the year or month either.
+
+  * Add cli.py, a simple script to query devices for debugging purposes.
+
+  * allow easier importing with from pyHS100 import SmartPlug
+
+  * move cli.py to examples, add short usage into README.md
+
+  * Implement more available APIs, refactor querying code.
+
+  This commit adds access to new properties, both read & write,  while keeping the old one (mostly) intact.
+  Querying is refactored to be done inside _query_helper() method,
+  which unwraps results automatically and rises SmartPlugException() in case of errors.
+  Errors are to be handled by clients.
+
+  New features:
+  * Setting device alias (plug.alias = "name")
+  * led read & write
+  * icon read (doesn't seem to return anything without cloud support at least), write API is not known, throws an exception currently
+  * time read (returns datetime), time write implemented, but not working even when no error is returned from the device
+  * timezone read
+  * mac read & write, writing is untested for now.
+
+  Properties for easier access:
+  * hw_info: return hw-specific elements from sysinfo
+  * on_since: pretty-printed from sysinfo
+  * location: latitude and longitued from sysinfo
+  * rssi: rssi from sysinfo
+
+  * Update README.md with examples of available features.
+
+  * Handle comments from mweinelt
+
+  * Refactor state handling, use booleans instead of strings
+
+  * Fix issues raised during the review.
+
+  Following issues are addressed by this commit:
+  * All API is more or less commented (including return types, exceptions, ..)
+  * Converted state to use
+  * Added properties is_on, is_off for those who don't want to check against strings.
+  * Handled most issues reported by pylint.
+  * Adjusted _query_helper() to strip off err_code from the result object.
+  * Fixed broken format() syntax for string formattings.
+
+  * Fix ci woes plus one typo.
+
+  * Do initialization after changing device properties, fix nits.

-# Preparing the changelog
-
-Looks like gitchangelog is not as nice as thought before,
-however, you can generate the changelog by doing this:
-
-$ gitchangelog 0.x.y..HEAD
-
-and manually placing the output to CHANGELOG and fixing
-the newlines between commit messages, and cleaning up the
-unnecessary entries,  and finally commiting the file.
-
-After that prepare a pull request containing the changed,
-release-related files (CHANGELOG, setup.py, README, ..).
-
-# After release merge is done
-
-$ git tag -a v0.x.y -m "0.x.y"
