+    - [Enhancement] Made internal adjustments to the [[visual3d:documentation:definitions:file_formats:hdf5|HDF5-based file format]] that result in up to 50% smaller files than previously.
+    - [Enhancement] Adjusted the shoulder's [[visual3d:documentation:kinematics_and_kinetics:joint|joint radius ratio]] for Visual3D's [[visual3d:documentation:third-party:theia#automatic_model-building|automatic model for Theia3D data]], resulting in more robust modelling.
+    - [Bug Fix] Fixed a bug where Visual3D could crash when animating multiple motion files with [[visual3d:documentation:c3d_signal_types:data_not_found|DATA_NOT_FOUND]].
+    - [Bug Fix] Fixed a bug where Visual3D could crash if it failed to compute a defined [[visual3d:documentation:modeling:landmarks:landmarks_overview|landmark]].
+    - [Bug Fix] Fixed a bug where changing the start frame of a motion file from another CMZ under "Add/Modify Synchronization Motion Files" would cause Visual3D to crash.
+  - Updates for 2026.07.1
+    - [Pre-release] Preview for a new [[visual3d:documentation:definitions:file_formats:hdf5|HDF5-based file format]] for motion capture analysis as an alternative to the [[visual3d:documentation:definitions:file_formats:cmz_format|CMZ file format]]:
+      - The HDF5-based format is implemented alongside the existing CMZ format, which remains available throughout Visual3D
+      - Save the new HDF5 file format through Visual3D's graphical interface as well as the [[visual3d:documentation:pipeline:file_commands:file_save|File_Save]] and [[visual3d:documentation:pipeline:file_commands:file_save_as|File_Save_As]] pipeline commands
+      - Load the new HDF5 file format through Visual3D's graphical interface as well as the [[visual3d:documentation:pipeline:file_commands:file_open|File_Open]] pipeline command
+      - Open Visual3D-saved H5 files with any utility or program that supports the HDF5 file format
+    - [New Feature] Added new [[visual3d:documentation:pipeline:signal_commands:moving_stddev|Moving_STDDEV]] pipeline command to calculate the Standard Deviation of a moving window.
+    - [Enhancement] Visual3D now defaults to building Theia3D's 2026 model, including baseball bat and ball segments when tracked, providing full support for [[visual3d:documentation:third-party:theia#version_requirements|Theia3D Apex]].
+    - [Enhancement] Visual3D's automatic model-builder now supports sex-specific regression equations from de Leva ([[visual3d:documentation:definitions:adjusted_zatsiorsky-seluyanov_s_segment_inertia_parameters|adjusted Zatsiorsky-Seluyanov]]) for calculating segment inertial properties.
+  - Updates for 2026.06.2
+    - [Enhancement] Updated the [[visual3d:documentation:pipeline:force_commands:fp_auto_baseline|FP_Auto_Baseline]] pipeline command to use different window sizes when treating forces derived from ORIGINAL and PROCESSED Analog signals.
+    - [Bug Fix] Fixed a bug where appending a model template to an existing model could result in segments defined as "[[visual3d:documentation:modeling:segments:virtual_segments|Kinematic Only]]" being assigned forces.
+  - Updates for 2026.06.1
+    - [New Feature] Added [[visual3d:documentation:pipeline:signal_commands:vector_coding|Vector Coding]] pipeline command.
+    - [Enhancement] Refactored automatic model building for markerless data.
+    - [Enhancement] The Link_Model_Based item [[visual3d:documentation:visual3d_signal_types:link_model_based_data_type:model_angular_momentum|MODEL_ANGULAR_MOMENTUM]] can now act across multiple subjects, including angular momentum of bat/club and player.
+    - [Enhancement] Updated [[visual3d:documentation:third-party:theia#automatic_model-building|automatic model-building for Theia3D]] output files to use [[visual3d:documentation:definitions:adjusted_zatsiorsky-seluyanov_s_segment_inertia_parameters|adjusted Zatsiorsky-Seluyanov]] regression equations for the pelvis and trunk segments when these values are not present in the C3D file.
+    - [Bug Fix] Modified [[visual3d:documentation:pipeline:event_commands:automatic_gait_events:event_create_at_selected_event|Event_Create_At_Selected_Event]] pipeline command so even if only one event from the list of events exists, it is still selected.
+  - Updates for 2026.04.2
+    - [Bug Fix] Fixed a bug causing the pipeline command [[visual3d:documentation:pipeline:signal_commands:set_data_to_new_values|Set_Data_To_New_Values]] to crash the application.
+  - Updates for 2026.04.1
+    - [New Feature] Added Ball modelling to [[visual3d:documentation:third-party:theia#automatic_model-building|automatic model for Theia3D data]].
+    - [Enhancement] Implemented both [[visual3d:documentation:third-party:theia#automatic_model-building|Ball and Bat modelling for Theia3D data]] using [[visual3d:documentation:definitions:multisubject|multiple subjects]], allowing multiple Ball and Bat objects to be modelled within a single session.
+    - [Enhancement] Added an Animation_Frame parameter to the [[visual3d:documentation:pipeline:other_commands:set_camera_perspective|Set_Camera_Perspective]] command, allowing the user to programmatically set the animation frame prior to saving images.
+    - [Bug Fix] Fixed a bug in [[visual3d:documentation:kinematics_and_kinetics:external_forces:force_assignment|Force Assignments]] when more than 1 custom force was manually assigned to a segment.
+    - [Bug Fix] Fixed a bug in [[visual3d:documentation:reports:reports_overview|Report Graphs]] in which [[visual3d:documentation:definitions:cmo_library#active_files_in_the_cmo_library|ALL_CMO_GLOBALS]] did not populate the dialog.
+    - [Bug Fix] Fixed a bug in the [[visual3d:documentation:pipeline:signal_commands:add_constant_to_signals|Add_Constant_To_Signals]], [[visual3d:documentation:pipeline:signal_commands:subtract_constant_from_signals|Subtract_Constant_From_Signals]], [[[[visual3d:documentation:pipeline:signal_commands:multiply_signals_by_constant|Multiply_Signals_By_Constant]], and [[visual3d:documentation:pipeline:signal_commands:divide_signal_by_constant|Divide_Signal_By_Constant]] commands where the specified signal component was used inconsistently compared to previous versions of Visual3D.
+  - Updates for 2026.03.2
+    - [Enhancement] Code refactor for processing markerless motion capture data.
+    - [Bug Fix] The "Create New Muscle" button in the Model-builder's [[visual3d:documentation:modeling:muscles:muscles_overview|Muscles tab]] did not work; this has been fixed.
   - Updates for 2026.03.1
     - [New Feature] Added [[visual3d:documentation:pipeline:file_commands:append_recalc_pipeline|Append_Recalc_Pipeline]] command which allows users to append pipeline commands to the workspace's RECALC pipeline.

     - [Bug Fix] Fixed a bug where using the [[visual3d:documentation:pipeline:force_commands:remove_segment_assignment_to_force_and_cop|Remove_Segment_Assignment_To_Force_And_COP]] command for multiple files without a start and end frame would lead to a crash.
     - [Bug Fix] Fixed a bug where components from [[visual3d:documentation:pipeline:metric_commands:metric_signal_value_at_event|Metric_Signal_Value_At_Event]]'s legacy parameter SIGNAL_COMPONENTS would not be correctly matched with their corresponding signals.
-    - [Bug Fix] Fixed a bug where the [[visual3d:documentation:pipeline:signal_commands:compute_volume_of_a_convex_hull_across_frames|Metric_Compute_Volume_of_a_Convex_Hull_Across_Frames]] command would not produce a result.
