+# Release Notes
+
+## _v2.2.1 (20171025)_
+
+**[Features]**
+- Support for sending and decoding Nikai TV messages. (#311, #313)
+- gc_decode: External utility to decode Global Cache codes. (#308, #312)
+- IRMQTTServer: Example code to send IR messages via HTTP & MQTT. (#316, #323)
+- Improve converting 64bit values to hexidecimal. (#318)
+
+**[Misc]**
+- IRrecvDump.ino code is now deprecated. Use IRrecvDumpV2.ino instead. (#314)
+
+
+## _v2.2.0 (20170922)_
+
+**[Bug Fixes]**
+- Add printing output of RC-MM and RC-5X protocols in example code. (#284)
+- LG timing improvements based on observations (#291)
+
+**[Features]**
+- Automatic capture timing calibration for some protocols. (#268)
+- Support for creating & sending Trotec AC codes. (#279)
+- Support for creating & sending Argo Ulisse 13 DCI codes. (#280 #300)
+- Move to 2 microsecond timing resolution for capture of codes. (#287)
+- Capture buffer changes:
+- Size at runtime. (#276)
+- Message timeout at runtime. (#294)
+- Simplify creating & using a second buffer (#303)
+- New example code:
+  - Trotec A/C (#279)
+  - LG A/C units (#289)
+  - Argo Ulisse 13 DCI codes. (#300)
+
+
+## _v2.1.1 (20170711)_
+
+**[Bug Fixes]**
+- GlobalCache incorrectly using hardware offset for period calc. (#267)
+
+**[Features]**
+- Support reporting of 'NEC'-like 32-bit protocols. e.g. Apple TV remote (#265)
+- Add an example of sendRaw() to IRsendDemo.ino (#270)
+
+
+## _v2.1.0 (20170704)_
+
+**[Features]**
+- Support for sending Pronto IR codes. (#248)
+- Support for sending Fujitsu A/C codes. (#88)
+- Minor improvements to examples.
+
+
+## _v2.0.3 (20170618)_
+
+**[Bug fixes]**
+- Capture buffer could become corrupt after large message, breaking subsequent decodes. (#253)
+
+
+## _v2.0.2 (20170615)_
+
+**[Bug fixes]**
+- Correct decode issue introduced in v2.0.1 affecting multiple protocol decoders (#243)
+- Correct post-message gap for the Panasonic protocol(s) (#245)
+- Incorrect display of the decoded uint64_t value in the example code. (#245)
+
+
+## _v2.0.1 (20170614)_
+
+**[Bug fixes]**
+- Decoding protocols when it doesn't detect a post-command gap, and there is no more data. (#243)
+- Incorrect minimum size calculation when there is no post-command gap. (#243)
+
+
+## _v2.0.0 - 64 bit support and major improvements (20170612)_
+
+**[Misc]**
+- This is almost a complete re-write of the library.
+
+**[Features]**
+- All suitable protocols now handle 64-bit data messages and are repeatable via an optional argument.
+- Unit tests for all protocols.
+- Far better and stricter decoding for most protocols.
+- Address & command decoding for protocols where that information is available.
+- Much more precise timing for generation of signals sent.
+- Lower duty-cycles for some protocols.
+- Several new protocols added, and some new sending and decoding routines for existing ones.
+- Ability to optionally chose which protocols are included, enabling faster decoding and smaller code footprints if desired.
+- Support for far larger capture buffers. (e.g. RAWLEN > 256)
+
+**[Bug fixes]**
+- Numerous bug fixes.
+
+
+## _v1.2.0 (20170429)_
+
+**[Features]**
+- Add ability to copy IR capture buffer, and continue capturing. Means faster and better IR command decoding.
+- Reduce IRAM usage by 28 bytes.
+- Improve capture of RC-MM & Panasonic protocols.
+- Upgrade IRrecvDumpV2 to new IR capture buffer. Much fewer corrupted/truncated IR messages.
+
+
+## _v1.1.1 (20170413)_
+
+**[Bug fixes]**
+- Fix a reported problem when sending the LG protocol. Preemptive fix for possible similar cases.
+- Fix minor issues in examples.
+
+**[Features]**
+- Add documentation to some examples to aid new people.
+- Add ALPHA support for RC-MM protocol. (Known to be currently not 100% working.)
