+  Features
+
+  - Lib:
+    - Function iterp: test whether an object is an iterator.
+    - Iterable ranges  with skip factor: 1..10..2, "aa".."dd"..4.
+    - Function progf: pass arguments to each function in a list,
+      returning value of last one.
+    - rand: bits of PRNG now used more efficiently:
+      - e.g. 32 successive (rand 2) calls use a single 32 bit
+        random word pulled from PRNG.
+    - Functions remove, keep: generalized remqual and keepqual.
+
+  - System Interface:
+    - glob* now supports string and integer ranges in brace expansion,
+      similarly to bash.
+      - Bash has only single-character ranges like {a..z}, whereas
+        we have {aa...zz} and such.
+      - also: new bexp function now exposes glob*'s brace expansion.
+
+  - Syntax:
+    - letrec macro.
+    - case, case*, ecase and ecase* synonym macros for casequal family,
+      for nicer readability.
+    - new mul and div macros to update a place by multiplying
+      or dividing its current value.
+
+  - Read syntax:
+    - quasiliteral substitutions can now specify format directive,
+      e.g.  `@~3,2f:a` is like `@a`, but with ~3,2f format directive
+      applied.
+    - referencing dot allows white space on right side
+      - thus chains like obj.(meth arg).next ... can be split
+        across lines now.
+    - symbols can contain | character.
+
+  - Expansion:
+    - *expand-hook* feature.
+    - noexpand mechanism to annotate code as not requiring expansion.
+    - ifx macro provides infix.
+      - c-like operators for bit operations.
+      - squared functions: sin ** 2 x  is sine squared x.
+      - novel precedence algorithm for intuitive parses.
+      - superfix relational comparisons 0 < x <= j < k.
+
+  - Pattern Matching
+    - New match-tuple-case macro
+    - @(require) operator now possible over argument tuples in
+      lambda-match.
+    - new macros in the "each" family:
+      - each-match-case, collect-match-cases, append-match-cases,
+        keep-match-cases, ... and others.
+
+  - Data Integrity
+    - HMAC: functions hmac-sha1, hmac-sha256 and hmac-md5.
+    - sha1-hash, sha256-hash, md5-hash now take stream argument.
+
+  - Data Compression
+    - str-compress and str-decompress functions directly compress
+      and decompress strings as UTF-8.
+
+  - listener:
+    - auto-infix mode.
+      - works with auto-compound mode.
+      - TXR can be used as infix calculator easily.
+
+  - buffers:
+    - now support bit operations
+      - functions buf-and, buf-ash, and others.
+      - also integrated into math lib: logand, ash, ... work on buffers.
+    - make-buf and buf-set-length can fill with multi-byte-patterns,
+      specified as a buffer or integer.
+    - improvement in buf representation, streamlining all code touching it.
+
+   - streams:
+     - better support for mixed character and byte push-back
+       in file/socket/pipe streams.
+     - string byte input streams support character input,
+       any mixture of unget-byte and unget-char operations,
+       and also fill-buf.
+     - much improved support for mixed parsing and
+       regular I/O operations.
+       - after iread or get-json, we can read the characters
+         which immediately follow, and then having consumed
+         what we need, do another iread or get-json.
+     - string output streams support truncate-stream and seek-stream.
+     - string input stream supports seek-stream.
+     - buffers streams similarly improved.
+
+  - debugging:
+    - new parameter macro :trace lets any function be statically traced.
+      - uses same mechanism as trace, but does not turn on/off
+        dynamically
+      - works with any function anywhere: flet, labels, lambdas.
+
+  - compiler:
+    - minor optimization improvements.
+    - diagnostic improvements (origin tracing).
+
+  - build:
+    - New utility "config-cache-hook.tl" available in tree for caching
+      build configurations, for faster git bisect and whatnot.
+
+  Bugs
+
+  - build:
+    - configure: bad gcc version check.
+    - Makefile: don't create .build_id for non-users of build_id.
+  - setenv: checks for error from C setenv and throw.
+  - buffers: conversion of zero-sized buffer to integer was asserting.
+  - listener: abort when Tab-completing sym with non-existent package.
+  - signals: SIGSYS considered synchronous signal like SIGFPE, etc.
+  - listener: fixed 2021 regression causing no Tab completion on keywords.
