 List of major changes and improvements between releases
 =======================================================
 
-Yosys 0.10 .. Yosys 0.10-dev
+Yosys 0.16 .. Yosys 0.16-dev
+--------------------------
+
+ * SystemVerilog
+    - Fixed automatic `nosync` inference for local variables in `always_comb`
+      procedures not applying to nested blocks and blocks in functions
+
+Yosys 0.15 .. Yosys 0.16
+--------------------------
+ * Various
+    - Added BTOR2 witness file co-simulation.
+    - Simulation calls external vcd2fst for VCD conversion.
+    - Added fst2tb pass - generates testbench for the circuit using
+      the given top-level module and simulus signal from FST file.
+    - yosys-smtbmc: Option to keep going after failed assertions in BMC mode
+
+ * Verific support
+    - Import modules in alphabetic (reproducable) order.
+
+Yosys 0.14 .. Yosys 0.15
+--------------------------
+
+ * Various
+    - clk2fflogic: nice names for autogenerated signals
+    - simulation include support for all flip-flop types.
+    - Added AIGER witness file co-simulation.
+
+ * Verilog
+    - Fixed evaluation of constant functions with variables or arguments with
+      reversed dimensions
+    - Fixed elaboration of dynamic range assignments where the vector is
+      reversed or is not zero-indexed
+    - Added frontend support for time scale delay values (e.g., `#1ns`)
+
+ * SystemVerilog
+    - Added support for accessing whole sub-structures in expressions
+ 
+ * New commands and options
+    - Added glift command, used to create gate-level information flow tracking
+      (GLIFT) models by the "constructive mapping" approach
+
+ * Verific support
+    - Ability to override default parser mode for verific -f command.
+
+Yosys 0.13 .. Yosys 0.14
+--------------------------
+
+ * Various
+    - Added $bmux and $demux cells and related optimization patterns.
+
+ * New commands and options
+    - Added "bmuxmap" and "dmuxmap" passes 
+    - Added "-fst" option to "sim" pass for writing FST files
+    - Added "-r", "-scope", "-start", "-stop", "-at", "-sim", "-sim-gate",
+      "-sim-gold" options to "sim" pass for co-simulation
+
+ * Anlogic support
+    - Added support for BRAMs
+
+Yosys 0.12 .. Yosys 0.13
+--------------------------
+
+ * Various
+    - Use "read" command to parse HDL files from Yosys command-line
+    - Added "yosys -r <topmodule>" command line option
+    - write_verilog: dump zero width sigspecs correctly
+
+ * SystemVerilog
+    - Fixed regression preventing the use array querying functions in case
+      expressions and case item expressions
+    - Fixed static size casts inadvertently limiting the result width of binary
+      operations
+    - Fixed static size casts ignoring expression signedness
+    - Fixed static size casts not extending unbased unsized literals
+    - Added automatic `nosync` inference for local variables in `always_comb`
+      procedures which are always assigned before they are used to avoid errant
+      latch inference
+
+ * New commands and options
+    - Added "clean_zerowidth" pass
+
+ * Verific support
+    - Add YOSYS to the implicitly defined verilog macros in verific
+
+Yosys 0.11 .. Yosys 0.12
+--------------------------
+
+ * Various
+    - Added iopadmap native support for negative-polarity output enable
+    - ABC update
+
+ * SystemVerilog
+    - Support parameters using struct as a wiretype
+
+ * New commands and options
