-Changes from v1.2?
+Here is a list of changes between 1v0 and 1v31:
 
-v1.2
-****
+1. Additional SAW filters with matching networks have been added:
+
+   Cell Band 01: U160
+
+   Cell Band 02: U164, L121
+
+   Cell Band 03: U165, L122, L123
+
+   Cell Band 07: U166, L124, L125
+
+2. GPIO pins have been modified so that GPIO0 and GPIO1 now support Arduino interrupt routines (IR).
+
+   LNA_EN and PA_ENn have been moved at the MCU from pins 1 and 32 to pins 14 and 13, respectively.
+
+   GPIO1_MCU and GPIO0_MCU are now connected to MCU interrupt pins INT1 and INT0 (pins 1 and 32), respectively.
+
+3. To support TDD operation without an interrupt routine (IR), U167 has been added.
+
+   An inverter was also added to make BAND38_TX_ENn active low.
+
+4. R138 has been added so that the ICSP is directly connected to +5V_MCU node.
+
+5. Since the PE4245 was not available on the market, it has been replaced with the HMC544AE.
+
+   Affected components: U61, U63
+
+   Control signals for the new switches are generated by U137. These control signals are now 3 V instead of the previous 2.5 V.
+
+6. The HAM3500 PA designated as MAAM-009560 has been replaced with the MMZ38333, and the surrounding circuitry has been modified accordingly.
+
+7. The section between U57 (cellular predriver) and U86 (RF switch) has been changed from:
+
+   MADL-011021-14150T (U160, limiter) 
+
+   PAT1220-C-3DB-T5 (U161, attenuator)
+
+   to:
+
+   PAT1220-C-3DB-T5 (U149, not fitted, attenuator)
+
+   MADL-011008-14120T (U150, limiter)
+
+   PAT1220-C-5DB-T5 (U161, not fitted, attenuator)
+
+   Additionally, C150, C151, and L120 have been added.
+
+8. GPIO0, GPIO1, GPIO4 and GPIO5 have been changed, which caused additional GPIO pins remapping on several connectors and components.
+
+   GPIO remapping on Q3–Q6, U27, U28, SW2, J13, and U23–U26:
+   from GPIO0, GPIO1, GPIO2, GPIO3 
+   to GPIO2, GPIO3, GPIO4, GPIO5.
+
+   This also remapped RELAY_0, RELAY_1, RELAY_2, and RELAY_3
+   from GPIO0, GPIO1, GPIO2, GPIO3
+   to GPIO2, GPIO3, GPIO4, GPIO5.
+
+   J22 connector remapping:
+   GPIO5, GPIO3, GPIO3_CONN changed to GPIO1, GPIO5, GPIO5_CONN.
+
+   J12 connector remapping:
+   GPIO0, GPIO1, GPIO2, GPIO3_CONN, GPIO4, GPIO5
+   changed to GPIO0, GPIO1, GPIO2, GPIO3, GPIO4, GPIO5_CONN.
