-
-* Relays public channel messages between mattermost, IRC, XMPP, Gitter and Slack. Pick and mix.
-* Supports multiple channels.
-* Matterbridge can also work with private groups on your mattermost.
-
-Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for documentation and an example.
-
-## Changelog
-Since v0.6.1 support for XMPP, Gitter and Slack is added. More details in [changelog.md] (https://github.com/42wim/matterbridge/blob/master/changelog.md)
-
-## Requirements:
-Accounts to one of the supported bridges
-* [Mattermost] (https://github.com/mattermost/platform/)
-* [IRC] (http://www.mirc.com/servers.html)
-* [XMPP] (https://jabber.org)
-* [Gitter] (https://gitter.im)
-* [Slack] (https://www.slack.com)
-
-## binaries
-Binaries can be found [here] (https://github.com/42wim/matterbridge/releases/)
-* For use with mattermost 3.3.0+ [v0.6.1](https://github.com/42wim/matterircd/releases/tag/v0.6.1)
-* For use with mattermost 3.0.0-3.2.0 [v0.5.0](https://github.com/42wim/matterircd/releases/tag/v0.5.0)
-
-
-## Docker
-Create your matterbridge.conf file locally eg in ```/tmp/matterbridge.conf```
-
-```
-docker run -ti -v /tmp/matterbridge.conf:/matterbridge.conf 42wim/matterbridge:0.6.1
-```
-
-## Compatibility
-### Mattermost 
-* Matterbridge v0.6.1 works with mattermost 3.3.0 and higher [3.3.0 release](https://github.com/mattermost/platform/releases/tag/v3.3.0)
-* Matterbridge v0.5.0 works with mattermost 3.0.0 - 3.2.0 [3.2.0 release](https://github.com/mattermost/platform/releases/tag/v3.2.0)
-
-
-#### Webhooks version
-* Configured incoming/outgoing [webhooks](https://www.mattermost.org/webhooks/) on your mattermost instance.
-
-#### Plus (API) version
-* A dedicated user(bot) on your mattermost instance.
-
-
-## building
-Go 1.6+ is required. Make sure you have [Go](https://golang.org/doc/install) properly installed, including setting up your [GOPATH] (https://golang.org/doc/code.html#GOPATH)
-
-```
-cd $GOPATH
-go get github.com/42wim/matterbridge
-```
-
-You should now have matterbridge binary in the bin directory:
-
-```
-$ ls bin/
-matterbridge
-```
-
-## running
-1) Copy the matterbridge.conf.sample to matterbridge.conf in the same directory as the matterbridge binary.  
-2) Edit matterbridge.conf with the settings for your environment. See below for more config information.  
-3) Now you can run matterbridge. 
-
-```
-Usage of ./matterbridge:
-  -conf string
-        config file (default "matterbridge.conf")
-  -debug
-        enable debug
-  -plus
-        running using API instead of webhooks (deprecated, set Plus flag in [general] config)
-  -version
-        show version
-```
-
-## config
-### matterbridge
-matterbridge looks for matterbridge.conf in current directory. (use -conf to specify another file)
-
-Look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for an example.
-
-### mattermost
-#### webhooks version
-You'll have to configure the incoming and outgoing webhooks. 
-
-* incoming webhooks
-Go to "account settings" - integrations - "incoming webhooks".  
-Choose a channel at "Add a new incoming webhook", this will create a webhook URL right below.  
-This URL should be set in the matterbridge.conf in the [mattermost] section (see above)  
-
-* outgoing webhooks
-Go to "account settings" - integrations - "outgoing webhooks".  
-Choose a channel (the same as the one from incoming webhooks) and fill in the address and port of the server matterbridge will run on.  
-
-e.g. http://192.168.1.1:9999 (192.168.1.1:9999 is the BindAddress specified in [mattermost] section of matterbridge.conf)
-
-#### plus version
-You'll have to create a new dedicated user on your mattermost instance.
-Specify the login and password in [mattermost] section of matterbridge.conf
-
-## FAQ
-Please look at [matterbridge.conf.sample] (https://github.com/42wim/matterbridge/blob/master/matterbridge.conf.sample) for more information first. 
-### Mattermost doesn't show the IRC nicks
-If you're running the webhooks version, this can be fixed by either:
-* enabling "override usernames". See [mattermost documentation](http://docs.mattermost.com/developer/webhooks-incoming.html#enabling-incoming-webhooks)
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
-
-If you're running the plus version you'll need to:
-* setting ```PrefixMessagesWithNick``` to ```true``` in ```mattermost``` section of your matterbridge.conf.
-
-Also look at the ```RemoteNickFormat``` setting.

+* general: various improvements
+* general: samechannelgateway now relays messages correct again #207
+
+
 # v0.16.0-rc2
 ## Breaking Changes

+
+     a. under intellectual property rights (other than patent or trademark)
+        Licensable by such Contributor to use, reproduce, make available,
+        modify, display, perform, distribute, and otherwise exploit its
+        Contributions, either on an unmodified basis, with Modifications, or
+        as part of a Larger Work; and
+
+     b. under Patent Claims of such Contributor to make, use, sell, offer for
+        sale, have made, import, and otherwise transfer either its
+        Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+     The licenses granted in Section 2.1 with respect to any Contribution
+     become effective for each Contribution on the date the Contributor first
+     distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+     The licenses granted in this Section 2 are the only rights granted under
+     this License. No additional rights or licenses will be implied from the
+     distribution or licensing of Covered Software under this License.
+     Notwithstanding Section 2.1(b) above, no patent license is granted by a
+     Contributor:
+
+     a. for any code that a Contributor has removed from Covered Software; or
+
+     b. for infringements caused by: (i) Your and any other third party's
+        modifications of Covered Software, or (ii) the combination of its
+        Contributions with other software (except as part of its Contributor
+        Version); or
+
+     c. under Patent Claims infringed by Covered Software in the absence of
+        its Contributions.
+
+     This License does not grant any rights in the trademarks, service marks,
+     or logos of any Contributor (except as may be necessary to comply with
+     the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+     No Contributor makes additional grants as a result of Your choice to
+     distribute the Covered Software under a subsequent version of this
+     License (see Section 10.2) or under the terms of a Secondary License (if
+     permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+     Each Contributor represents that the Contributor believes its
+     Contributions are its original creation(s) or it has sufficient rights to
+     grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+     This License is not intended to limit any rights You have under
+     applicable copyright doctrines of fair use, fair dealing, or other
+     equivalents.
+
+2.7. Conditions
+
+     Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
+     Section 2.1.
+
+
+3. Responsibilities
+
+3.1. Distribution of Source Form
+
+     All distribution of Covered Software in Source Code Form, including any
+     Modifications that You create or to which You contribute, must be under
+     the terms of this License. You must inform recipients that the Source
+     Code Form of the Covered Software is governed by the terms of this
+     License, and how they can obtain a copy of this License. You may not
+     attempt to alter or restrict the recipients' rights in the Source Code
+     Form.
+
+3.2. Distribution of Executable Form
+
+     If You distribute Covered Software in Executable Form then:
+
+     a. such Covered Software must also be made available in Source Code Form,
+        as described in Section 3.1, and You must inform recipients of the
+        Executable Form how they can obtain a copy of such Source Code Form by
+        reasonable means in a timely manner, at a charge no more than the cost
+        of distribution to the recipient; and
+
+     b. You may distribute such Executable Form under the terms of this
+        License, or sublicense it under different terms, provided that the
+        license for the Executable Form does not attempt to limit or alter the
+        recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+     You may create and distribute a Larger Work under terms of Your choice,
+     provided that You also comply with the requirements of this License for
+     the Covered Software. If the Larger Work is a combination of Covered
+     Software with a work governed by one or more Secondary Licenses, and the
+     Covered Software is not Incompatible With Secondary Licenses, this
+     License permits You to additionally distribute such Covered Software
+     under the terms of such Secondary License(s), so that the recipient of
+     the Larger Work may, at their option, further distribute the Covered
+     Software under the terms of either this License or such Secondary
+     License(s).
+
+3.4. Notices
+
+     You may not remove or alter the substance of any license notices
+     (including copyright notices, patent notices, disclaimers of warranty, or
+     limitations of liability) contained within the Source Code Form of the
+     Covered Software, except that You may alter any license notices to the
+     extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+     You may choose to offer, and to charge a fee for, warranty, support,
+     indemnity or liability obligations to one or more recipients of Covered
+     Software. However, You may do so only on Your own behalf, and not on
+     behalf of any Contributor. You must make it absolutely clear that any
+     such warranty, support, indemnity, or liability obligation is offered by
+     You alone, and You hereby agree to indemnify every Contributor for any
+     liability incurred by such Contributor as a result of warranty, support,
+     indemnity or liability terms You offer. You may include additional
+     disclaimers of warranty and limitations of liability specific to any
+     jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+
+   If it is impossible for You to comply with any of the terms of this License
+   with respect to some or all of the Covered Software due to statute,
+   judicial order, or regulation then You must: (a) comply with the terms of
+   this License to the maximum extent possible; and (b) describe the
+   limitations and the code they affect. Such description must be placed in a
+   text file included with all distributions of the Covered Software under
+   this License. Except to the extent prohibited by statute or regulation,
+   such description must be sufficiently detailed for a recipient of ordinary
+   skill to be able to understand it.
+
+5. Termination
+
+5.1. The rights granted under this License will terminate automatically if You
+     fail to comply with any of its terms. However, if You become compliant,
+     then the rights granted under this License from a particular Contributor
+     are reinstated (a) provisionally, unless and until such Contributor
+     explicitly and finally terminates Your grants, and (b) on an ongoing
+     basis, if such Contributor fails to notify You of the non-compliance by
+     some reasonable means prior to 60 days after You have come back into
+     compliance. Moreover, Your grants from a particular Contributor are
+     reinstated on an ongoing basis if such Contributor notifies You of the
+     non-compliance by some reasonable means, this is the first time You have
+     received notice of non-compliance with this License from such
+     Contributor, and You become compliant prior to 30 days after Your receipt
+     of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+     infringement claim (excluding declaratory judgment actions,
+     counter-claims, and cross-claims) alleging that a Contributor Version
+     directly or indirectly infringes any patent, then the rights granted to
+     You by any and all Contributors for the Covered Software under Section
+     2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
+     license agreements (excluding distributors and resellers) which have been
+     validly granted by You or Your distributors under this License prior to
+     termination shall survive termination.
+
+6. Disclaimer of Warranty
+
+   Covered Software is provided under this License on an "as is" basis,
+   without warranty of any kind, either expressed, implied, or statutory,
+   including, without limitation, warranties that the Covered Software is free
+   of defects, merchantable, fit for a particular purpose or non-infringing.
+   The entire risk as to the quality and performance of the Covered Software
+   is with You. Should any Covered Software prove defective in any respect,
+   You (not any Contributor) assume the cost of any necessary servicing,
+   repair, or correction. This disclaimer of warranty constitutes an essential
+   part of this License. No use of  any Covered Software is authorized under
+   this License except under this disclaimer.
+
+7. Limitation of Liability
+
+   Under no circumstances and under no legal theory, whether tort (including
+   negligence), contract, or otherwise, shall any Contributor, or anyone who
+   distributes Covered Software as permitted above, be liable to You for any
+   direct, indirect, special, incidental, or consequential damages of any
+   character including, without limitation, damages for lost profits, loss of
+   goodwill, work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses, even if such party shall have been
+   informed of the possibility of such damages. This limitation of liability
+   shall not apply to liability for death or personal injury resulting from
+   such party's negligence to the extent applicable law prohibits such
+   limitation. Some jurisdictions do not allow the exclusion or limitation of
+   incidental or consequential damages, so this exclusion and limitation may
+   not apply to You.
+
+8. Litigation
+
+   Any litigation relating to this License may be brought only in the courts
+   of a jurisdiction where the defendant maintains its principal place of
+   business and such litigation shall be governed by laws of that
+   jurisdiction, without reference to its conflict-of-law provisions. Nothing
+   in this Section shall prevent a party's ability to bring cross-claims or
+   counter-claims.
+
+9. Miscellaneous
+
+   This License represents the complete agreement concerning the subject
+   matter hereof. If any provision of this License is held to be
+   unenforceable, such provision shall be reformed only to the extent
+   necessary to make it enforceable. Any law or regulation which provides that
+   the language of a contract shall be construed against the drafter shall not
+   be used to construe this License against a Contributor.
+
+
+10. Versions of the License
+
+10.1. New Versions
+
+      Mozilla Foundation is the license steward. Except as provided in Section
+      10.3, no one other than the license steward has the right to modify or
+      publish new versions of this License. Each version will be given a
+      distinguishing version number.
+
+10.2. Effect of New Versions
+
+      You may distribute the Covered Software under the terms of the version
+      of the License under which You originally received the Covered Software,
+      or under the terms of any subsequent version published by the license
+      steward.
+
+10.3. Modified Versions
+
+      If you create software not governed by this License, and you want to
+      create a new license for such software, you may create and use a
+      modified version of this License if you rename the license and remove
+      any references to the name of the license steward (except to note that
+      such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+      Licenses If You choose to distribute Source Code Form that is
+      Incompatible With Secondary Licenses under the terms of this version of

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+Package client provides bindings for the etcd APIs.

+
+	// create a new key /foo with the value "bar"
+	_, err = kAPI.Create(context.Background(), "/foo", "bar")

+	_, err = kAPI.Delete(context.Background(), "/foo", &DeleteOptions{PrevValue: "bar"})

+
+	// set a new key, ignoring its previous state
