Every version, easy to trace.

1. 01v0.2.11LatestGitHub release

   • Adds an experimental serial gyroscopic modal route for straight BEAM2 shafts with centered rigid axisymmetric disks.
   • Produces Campbell results with complex mode tracking, branch lineage, degeneracy handling, and ambiguity diagnostics.
   • Checks include zero speed behavior, formulation and frame checks, an analytical disk oscillator, signed speed spectral splitting, and internal mesh convergence. The route remains bounded and experimental.

2. 02v0.2.10GitHub release

   • Unifies selected nonlinear analyses around shared solve state and transactional trial, commit, and rollback handling.
   • Adds continuation and bounded arc length alongside selected geometric nonlinearity and small strain or bounded corotational J2 paths.
   • Includes scoped contact and friction work, Code_Aster correlation, and selected PETSc and MPI checks. These records do not qualify every nonlinear case.

3. 03v0.2.9Source tag only

   • Preserves a source snapshot between the v0.2.8 and v0.2.10 releases.
   • There is no matching GitHub release page or published installation package for this tag.
   • Nonlinear work from this development cycle is described with the v0.2.10 release. This tag does not add a separate qualification claim.

4. 04v0.2.8GitHub release

   • Introduces bounded serial mixed mesh paths using connected TET4, WEDGE6, and HEX8 regions for selected static and modal cases, translational MPCs, and multiple materials.
   • Adds experimental Newmark and harmonic routes, a limited .inp import subset, mixed HDF5 result storage, frictionless penalty contact, and HEX8 SRI as separately scoped capabilities.
   • Publishes 46 element and analysis records: 32 qualified within scope and 14 experimental. Each status remains limited to its documented workflow.

5. 05v0.2.7GitHub release

   • Extends bounded verification for TET4, TET10, HEX8, and HEX20, with separate WEDGE6 modal and small strain J2 routes.
   • Adds linear buckling and initial frictionless node to triangle contact workflows, while strengthening static, modal, harmonic, and transient checks.
   • Recorded PETSc and MPI runs reach about 10.1 million DOFs under named configurations. This is a documented workload, not a general scaling guarantee.

6. 06v0.2.6a0Source tag only

   • Development snapshot centered on verification and validation structure, capability registries, and evidence records.
   • Separates execution provenance, evidence review, and release decisions to improve traceability.
   • No matching GitHub release or installation package exists for this tag, and it adds no newly qualified FEM route.

7. 07v0.2.5a0GitHub pre release

   • Documents bounded small strain J2 paths for TET4, TET10, HEX8, and HEX20, plus Total Lagrangian elasticity for TET4 and HEX8.
   • Adds sparse linear buckling and frictionless contact within specific documented routes.
   • Expands robustness, failure, and performance evidence. Friction, finite kinematic J2, and arc length are not qualified by this tag.

8. 08v0.2.4a0GitHub pre release

   • Builds shared experimental nonlinear solid mechanics infrastructure with explicit trial, commit, and rollback states.
   • Documents small strain J2 paths for TET4, TET10, HEX8, and HEX20, plus full Newton solution within the stated scope.
   • Adds tangent checks, Newton diagnostics, and bounded Code_Aster correlation. Modified Newton, cyclic, and broader multi element routes remain outside that evidence.

9. 09v0.2.3a0GitHub pre release

   • Brings HEX8 and HEX20 into selected static, modal, Newmark transient, and harmonic workflows.
   • Adds matching engineering verification and packaging checks for the published alpha routes.
   • These records apply to documented element and analysis combinations. They do not qualify every model size or configuration.

10. 10v0.2.2a0Source tag only

    • Explores a shared backend structure and clearer solver diagnostics.
    • Prepares optional PETSc and SLEPc integrations and early large model work.
    • This is a source tag only. Read it as development history rather than an installable release or finished qualification.

11. 11v0.2.1-alphaSource tag only

    • Introduces early verification and validation traceability through a machine readable registry and command line checks.
    • Separates test results, evidence status, technical review, and release status.
    • Records a MITC4 architecture migration. This source tag has no matching release package.

12. 12v0.2.0-alphaGitHub pre release

    • First public alpha with a Python solver in a src layout, a public Python API, and a command line interface.
    • Begins routes for TET4 and TET10 solids, MITC3 and MITC4 shells, BEAM2 beams, and discrete entities. Maturity varies by analysis.
    • Exposes early static, modal, Newmark transient, harmonic, and bounded nonlinear paths with initial tests and CI. Alpha status does not imply certification.
