# Do not want to convert your 2.x program and use the 3.x library version?
The 3.x versions try to be backwards compatible, so you can easily run your old examples. But some functions like e.g. `sendNEC()` -see below- could not made backwards compatible,
so in this cases you must revisit your code and adapt it to the 3.x library.<br/>
If you program look like:
First consider to just use the [original 2.4 release form 2017](https://github.com/Arduino-IRremote/Arduino-IRremote/releases/tag/v2.4.0)
or the last backwards compatible [2.8 version](https://github.com/Arduino-IRremote/Arduino-IRremote/releases/tag/2.8.0) for you project.
It may be sufficient and deals flawlessly with 32 bit IR codes.<br/>
If not, the 3.x versions try to be backwards compatible, so you can easily run your old examples. But some functions like e.g. `sendNEC()` -see below- could not made backwards compatible.
The (old and deprecated) call of `irrecv.decode(&results)` uses the old MSB first decoders like in 2.x and sets the 32 bit codes in `results.value`!<br/>
But only the following decoders are available then: Denon, JVC, LG, NEC, Panasonic, RC5, RC6, Samsung, Sony.
it runs on the 3.x version as before. But only the following decoders are available then: Denon, JVC, LG, NEC, Panasonic, RC5, RC6, Samsung, Sony.
The `results.value` is set by the decoders for **NEC, Panasonic, Sony, Samsung and JVC** as MSB first like in 2.x!<br/>
The old functions `sendNEC()` and `sendJVC()` are deprecated and renamed to `sendNECMSB()` and `sendJVCMSB()` to make it clearer that they send data with MSB first,
which is not the standard for NEC and JVC. Use them to send your **old MSB-first 32 bit IR data codes**.

Use them to send your **old MSB-first 32 bit IR data codes**.
In the new version you will send NEC (and other) commands not by 32 bit codes but by a (constant) 8 bit address and an 8 bit command.
