#### WLED Version 16.0.1 Announcement

Read the full copy at https://github.com/wled/WLED/releases/tag/v16.0.1

I'm pleased to announce that since the release of 16.0.0, approximately 50% of WLED installs have downloaded the new release, with only a tiny number of issues reported relative to the install base. Also for those of you that help by sending the install/upgrade report, we have seen only a handful of people downgrade back to 0.15.

There were few key reasons for why this was released as 16.0.0 and not 0.16.0 - 

One example is that it is actually a major software change as the entire esp32 platform we run on top of is a major new version, the first time since esp32 support was added. 

Another is that it better reflects the fact that WLED is almost 10 years old and has over 2 million downloads, so it’s definitely not a pre-release version 0!



Therefore I think it's fair to say we recommend ALL users upgrade to this 16.0.1 maintenance release!

#### WLED Version 16.0 Announcement

It is finally here: the WLED team is excited to announce the 16.0 release!

Read the full copy at https://github.com/wled/WLED/releases/tag/v16.0.0

The WLED team is excited to announce this beta release of the forthcoming official release of the next major version.

**Warning**: this is a beta release!!  WLED strongly recommends that you take a backup of your config and presets and do not install this beta unless you have easy access to reflash via USB.

Please wait for the main release of version 16 if you do not have easy access to reflash via USB.


This has been 16 months in the making and revived contributions from 59 contributors and marks a significant point in the development of WLED.

The team would like to take this opportunity to particularly recognise the contribution of @blazoncek. While he chose to leave the development team at the end of December, he was a very important part of the development cycle for this version.

Hey fellow LED lovers, the WLED Team are pleased to announce the first maintenance release of the 0.15 version.

The main intention of this release is to include fixes for the 0.15.0 release and also back-port selected bug fixes from the main development branch.

There are a few new features as well that were considered low-risk enough to give you access in this release rather than waiting for 0.16 in the autumn.

While efforts have been made to ensure this release only acts to improve the experience over 0.15.0 as with any software upgrade, we do advise you take backups of your configs and presets before you upgrade and you might want to try on only a few of your devices before pushing to all your devices.

**New Features**
In this release you will find an additional bin file which is tech preview of V4 build for esp32 - Fresh installs *ONLY* - do not install this bin via OTA
The future release of 0.16 will use the ESP-IDF V4 for all the ESP32 family, however there are some challenges that the WLED team are working on to make this possible as an OTA upgrade.

DMX INPUT - All esp32 builds now have the DMX Input feature included (V4 needed for esp32 classic)

**Bug Fixes**
The key change in 0.15.1 is a change in configuration to use the I2S parallel output in preference to the RMT based driver wherever possible. This is because the RMT driver is very prone to flicker of the LEDs, especially when the esp32 is under heavy network activity.
The I2S based driver requires that all your LEDs are of the same chipset type and the length of a given output is no more than 600 LEDs.
