+  * New prameters:
+    - server::dist_noise_rate (default value: 0.0125)
+    - server::focus_dist_noise_rate (default value: 0.0125)
+    - server::land_dist_noise_rate (default value: 0.00125)
+    - server::land_focus_dist_noise_rate (default value: 0.00125)
+
+  * New command:
+    - "(dash (l POWER DIR) (r POWER DIR))"
+     This is an extension of the dash command. All version players
+     can use this format. If the command is accepted, players can
+     perform acceleration and direction change simultaneously based
+     on the bipedal dash model.
+
+    - "(gaussian_see)"
+     All version players can use this command. If the command is
+     accepted, rcssserver sent a reply message, "(ok gaussian_see)".
+     This command is used for a gaussian noise mode describing below.
+
+  * Introduce a bipedal dash model. Players can now independently
+    issue dash commands to the left and right legs. This means that
+    players can now apply different accelerations to each leg. With
+    the bipedal dash model, players can perform acceleration and
+    direction changes simultaneously, governed by differential drive
+    kinematics.
+
+    The rotation is calculated as:
+
+    rotation = (left_leg_vel.bx - right_leg_vel.bx)/(player_size*2)
+
+    where bx is the x-component of the vector with the player's
+    body direction as the x-axis.
+
+    The player's result velocity is calculated as:
+
+    vel = (left_leg_vel + right_leg_vel)/2
+
+    Stamina is consumed independently on the left and right legs,
+    and the total consumption is the sum of half of each leg:
+
+    stamina = stamina - (left_consumed/2 + right_consumed/2)
+
+  * Introduce a new gaussian observation noise model. This model is
+    activated by "(gaussian_see)" command and replaces the previous
+    quantization model. In this model, In this model, the noised
+    distance in the player's observation is determined by a
+    Gaussian distribution:
+
+      stddev = actual_dist * noise_rate + focus_dist * focus_noise_rate
+      noised_dist = max(0.0, normal_distribution(actual_dist, stddev))
+
+    where normal_distribution(mean, stddev) is a random number
+    generator based on a Gaussian distribution with given mean and
+    standard deviation. actual_dist represents the actual distance
+    between the observed object and the player, while focus_dist is
+    the distance between the observed object and the player's focus
+    point. noise_rate and focus_noise_rate are determined by
+    heterogeneous parameters, with default values defined as new
+    server parameters, uniformly set for all player types in the
+    current version. For ball and player observation,
+    server::dist_noise_rate and server::focus_dist_noise_rate are
+    applied, while for flags (landmark objects), server::land_dist_noise_rate
+    and server::focus_dist_noise_rate are applied.
+
+    The velocity noise formula is similar to the previous one.
+    The formula of dir_chg remains unchanged, while dist_chg is
+    calculated as:
+
+      dist_chg = actual_dist_chg * noised_dist / actual_dist
+
+    where actual_dist_chg represents the x-component of the velocity
+    vector with the direction from the player to the observed object
+    as the x-axis. The resulting dist_chg value is rounded to two
+    decimal places before being sent.
+
+  * Improve the JSON game log format. The format of each data has
+    been reviewed to make it easier to parse and the JSON rcg is
+    now recorded as a pure JSON file. The parser library is bundled
+    in rcssmonitor.
+
 [18.1.3]
   * Fix an issue in the penalty shootouts referee. If both teams
-  	score the same when finishing all extended trials, the penalty
-	shootouts referee will not end the game and the simulator will
-	get stuck. Thanks go to Omid Amini for providing the patch.
