 This is a **pre-release** intended for **early adopters** and those who'd like to give feedback. New betas will be released frequently, while I continue to fix issues and make other improvements/additions.
 
 The included handlers and utils are **still undergoing changes**, though the signal creator API (and signal content) should already be mostly stable.

 ## Recent changes
 
+* \[mod] Changed default **handler back-pressure** mechanism from `:dropping` to `:blocking` (eaiser for most users to understand and detect; override when calling [`add-handler!`](https://cljdoc.org/d/com.taoensso/telemere/CURRENT/api/taoensso.telemere#add-handler!)) (beta11)
 * \[mod] [`pr-signal-fn`](https://cljdoc.org/d/com.taoensso/telemere/CURRENT/api/taoensso.telemere.utils#pr-signal-fn) now takes only a **single opts map** (beta10)
 * \[mod] [User-level kvs](https://cljdoc.org/d/com.taoensso/telemere/CURRENT/api/taoensso.telemere#help:signal-options) are **no longer included by default** in handler output. `:incl-kvs?` option has been added to [`format-signal-fn`](https://cljdoc.org/d/com.taoensso/telemere/CURRENT/api/taoensso.telemere.utils#format-signal-fn) and [`pr-signal-fn`](https://cljdoc.org/d/com.taoensso/telemere/CURRENT/api/taoensso.telemere.utils#pr-signal-fn) (beta7)
 * \[mod] Middleware must now be a **single fn**, use [`comp-middleware`](https://cljdoc.org/d/com.taoensso/telemere/CURRENT/api/taoensso.telemere#comp-middleware) to create one fn from many (beta7)
