+                                    TXR 299
+                                   2025-02-16
+
+
+  Features
+
+  - Lib:
+    - New defenum macro for defining enumerated constants, which
+      get implemented as symbol macros.
+
+  - Data Interchange:
+    - New CSV support: get-csv, put-csv, tocsv.
+    - Follows RFC 4180 as much as it makes sense to.
+
+  - Awk:
+    - code generation improved:
+      - field separation handled by a lambda that is configured
+        whenever field separation is set up, such that it doesn't
+        have to switch at record parse time (Strategy or State Pattern).
+    - CSV support: fs variable (field separator) can be set to :csv.
+
+  - Performance:
+    - improvements in read-until-match and related functions.
+
+  - VM:
+    - several variants of the IF instruction now check for signal
+      when doing a backward branch, like JMP does.
+      - I discovered that some looping code was not interruptible
+        by Ctrl-C.
+      - Root cause was that backward JMP was optimized to an
+        backwards-branching IF instruction.
+  
+  - op:
+    - lop: behavior change in lop and related left-inserting
+      partial application operators: the arguments are no longer
+      inserted when argument variables @1, @2, ...  or @rest are present.
+    - lopip, lflow: more efficient expansion.
+      - we know that pipe line elements receive only one argument and so
+        we can eliminate the use of apply and lambda.
+    - New macro lop1.
+
+  Bugs
+
+  - Bug in match-case macro.
+  - json: incorrect defaulting of flat-p argument in put-json.
+  - FFI:
+    - broken return value handing for int8 and uint8.
+    - broken be-int16 closure return value.
+    - rewrote return value handing for endian types to read/write
+      the memory as a ffi_arg and just do conversions and swaps.
