What changed in WLED from 0 to 16

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

This has been almost one and a half years to finish but be assured it was worth the wait: there are many new awesome features from 59 contributors and it marks a significant point in the development of WLED.

While he has now stepped back from the WLED team, we 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.

We hope that the new version exceeds your expectations of a free-for-all open source software. We all contributed to this update in our spare time, driven by passion and the desire to make something useful for everyone.

If you enjoy the project and would like to support WLED developers, consider contributing in any way that feels right to you — whether that’s sharing feedback, helping others, write documentation, contributing code, or, if you’re able, making a donation:
