+# APEX 1.3.0 Changelog
+
+## Highlights
+
+APEX 1.3.0 introduces new structure-generation workflows, new property workflows, improved automatic supercell construction, stronger failure-handling behavior, and a substantially reworked GUI submission/retrieval workflow.
+
+Major additions include:

+- Finite-temperature lattice workflow improvements
+- Finite-temperature elasticity workflow support and example documentation
+- Annealing workflow support for LAMMPS
+- Shape-controlled automatic supercell generation
+- `req_calc`-based relaxation/property selection for joint workflows
+- GUI-side batched submission for large configuration sets
+- Multi-workflow progress tracking and retrieval in `apex gui`
+- Bohrium account defaults managed by `apex account`
+- Improved failed-step output retrieval, diagnostics, retry behavior, and early-break handling
+
+---
+
+## Core Features
+
+### Automatic Structure Construction
+
+- Added automatic lattice constant estimation based on composition-weighted atomic radii.
+- Added automatic supercell generation from composition tolerance.
+- Added optional maximum atom budget for automatic supercell construction.
+- Added shape-control modes for automatic supercell generation:
+  - `near_cubic`
+  - `xy_equal_z_free`, mainly for gamma-surface and slab-like workflows.
+- Added support for sublattice-aware random solid solution generation for:
+  - B2
+  - L1_2
+  - L1_0
+
+### RSS Workflow
+
+- Added RSS workflow support.
+- Added RSS example documentation.
+- Added support for prototype-aware and sublattice-aware RSS systems.
+- Added parent-lattice helpers, automatic parent-lattice resolution, and Warren-Cowley SRO-driven sampling utilities.
+
+### GammaSurface Workflow
+
+- Added GammaSurface workflow support.
+- Added GammaSurface example documentation.
+- Added shape-control support for slab-like gamma-surface supercells.
+- Added `apex preview` support for generating GIF previews of GammaSurface motion.
+
+### Grüneisen Parameters and Thermal Expansion Workflow
+
+- Added `gruneisen` workflow support based on phonon calculations at multiple symmetric volume strains.
+- Added both `sign_only` and `full` output modes; `full` can fit Birch-Murnaghan EOS data to estimate thermal expansion.
+- Extended LAMMPS/phonoLAMMPS and VASP paths for Grüneisen post-processing, and added dedicated tests and examples.
+
+### Finite-Temperature Lattice Workflow
+
+- Add finite-temperature lattice calculations with updated thermo output, temperature-aware reporting, pressure handling, and `c/a` post-processing.
+
+### Finite-Temperature Elasticity Workflow
+
+- Added finite-temperature elasticity workflow support.
+- Added finite-temperature elasticity example documentation.
+- Added finite-temperature elastic tensor fitting, stress post-processing, and derived elastic modulus output.
+
+### Annealing Workflow
+
+- Added LAMMPS annealing workflow support.
+- Improved generated annealing input scripts for heating, cooling, RDF output, and holding stages.
+
+### Workflow Selection and Submission
+
+- Added `req_calc`-based workflow selection for relaxation and property calculations.
+- Added support for skipping relaxation in joint workflows with `"relaxation": {"req_calc": false}` when property setup can use the structure-directory `POSCAR` directly.
+- Added explicit disabling of individual properties with `"req_calc": false`.
+- Added clearer submit-time path validation and workflow labeling support.
+- Added skip-completed behavior for already successful relaxation and property tasks when rerun is not requested.
+
+### Failure Handling and Retrieval
+
+- Added automatic break behavior when the relaxation step fails in joint workflows.
+- Added detailed failed-step diagnostics with last-step failure reasons, workflow IDs, and workflow UIDs.
+- Added failed-output retrieval support using debug artifacts and main logs from the latest failed steps.
+- Added archive-workflow retrieval support in `apex retrieve`, including UID-based fallback lookup when workflow-name lookup is insufficient.
+- Added retry-aware artifact download behavior for transient failures while avoiding retries for permanent missing-artifact cases.
+- Added per-task LAMMPS status records and debug artifacts, including:
+  - `apex_task_status.json`
+  - `.debug.log`
+  - `.debug.stdout`
+  - `.debug.stderr`
+
+### Reporting
+
+- Added richer report support for new and updated workflows, including finite-temperature lattice, finite-temperature elasticity, GammaSurface, and annealing outputs.
+- Added static-report support for finite-temperature lattice tables/plots and annealing artifact summaries.
+- Added report CLI controls for browser launch, host, and port.
+- Improved Dash report startup behavior and reduced duplicate report-page launches.
+
+---
+
+## User Experience
+
+- Added `apex gui`, a web-based interface for common APEX operations.
+- Added GUI-side batched submission for large configuration sets.
+- Added aggregated multi-workflow progress tracking and retrieval in `apex gui`.
+- Added GUI support for structure upload, POSCAR-driven interaction auto-detection, VASP/ABACUS interaction-table editing, and profile-specific default templates.
+- Added GUI-side account management and report/retrieve orchestration.
+- Added `apex account` for saving Bohrium identity and cloud defaults for easier repeated submission.
+- Added automatic Bohrium default injection while preserving user-provided config overrides.
+- Added `apex preview` for visualizing GammaSurface movement before submission.
+- Added automatic interaction-type detection from POSCAR content.
+- Improved failed-step messages by printing the reason from the latest failed step.
+- Added default configuration templates for LAMMPS, VASP, ABACUS, and GUI submit groups.
+
+---
+
+## Compatibility and Documentation
+
+- Updated README coverage for RSS, GUI usage, Bohrium account defaults, Gamma line/surface, `req_calc`, and finite-temperature elasticity.
+- Added runnable examples for RSS, GammaSurface, and finite-temperature elasticity.
+- Added GUI developer documentation.
+- Added `monty` to the package dependencies and constrained supported Python versions to `<3.13`.
+- Added support for Phonopy v4 in terms of phonon calculation.
