Hi everyone,
I’m happy to announce that major revisions to my Grok TiddlyWiki learning resource are done, on schedule and under budget. 
Changes
These revisions bring GTW up to date with many of the newest features in TiddlyWiki: procedures, functions, <% conditional expressions %>, custom widgets, parameterized field transclusions, and so on. Macros and similar older ways to achieve the same things are de-emphasized but still discussed. I’ve also read through the entire book and gotten a fresh set of reviewers, and we’ve corrected a number of things that had gotten slightly out of date over the years or could just be explained better (plus a couple of outright errors that had somehow escaped detection for three and a half years – oops!).
Perhaps conspicuously missing from this edition are cascades and more details and exercises on the newer filter run prefixes (e.g., :map, :filter, :reduce). I do hope to incorporate those in a future revision – they just didn’t quite fit in this one with the time budget I had available.
Your feedback is always welcome, preferably emailed to me or using the send feedback link at the bottom of an associated section in the book.
Getting it
You can find the new version on the website at Grok TiddlyWiki — Build a deep, lasting understanding of TiddlyWiki. You can also now directly clone a copy to your TiddlyHost account (so you can save your progress and customize the book), and the source code is now published on GitHub.
Housekeeping
A huge thanks to those of you who have helped this round by reviewing the changes or providing other kinds of assistance, especially @vilc and frazier, and to those who have already donated to support my work on this edition. For anyone who wanted to help but didn’t get a chance to turn around feedback in time, feel free to send it on as you get to it and I’ll incorporate it in the next update.
On that note, donations would be much appreciated, as always – while I enjoy working on GTW and love helping the TiddlyWiki community, the fact remains that these revisions took more than $4,000 worth of my time at my normal hourly rate and there are a lot of projects I could be working on. Partially funding my work ensures that I stay cheerful about the amount of time I’m volunteering and have a good reason to prioritize it, ensuring the project remains as sustainable over the long term as TiddlyWiki.
Also, if it’s been too long for anyone since they last talked about Grok TiddlyWiki and TiddlyWiki itself on their blog, social media, etc., this might be a good moment!
