# Changelog
## Latest Commit
## Version 0.7.3
### New Features
- Add start state checks for world collision, self-collision, and joint limits.
- Add finetune with dt scaling for `motion_gen.plan_single_js` to get more time optimal
trajectories in joint space planning.
- Improve joint space planning convergence, now succeeds in more planning problems with higher
accuracy.
### Changes in default behavior
- Some warp kernels are now compiled based on runtime parameters (dof), causing a slowdown in load
time for motion_gen. To avoid this slowdown, add an environment variable `CUROBO_USE_LRU_CACHE=1`
which will cache the runtime generated kernels.
### BugFixes & Misc.
- Fix bug in evaluator to account for dof maximum acceleration and jerk.
@@ -23,6 +32,17 @@ its affiliates is strictly prohibited.
- Add `g_dim` check for `int` in batched planning.
- Add `link_poses` for motion_gen.warmup() in batch planning mode.
- Add `link_poses` as input to `batch_goalset`.
- Add finetune js trajopt solver.
- Pass raw velocity, acceleration, and jerk values to dt computation function to prevent
interpolation errors from causing out of joint limit failures
- Add `finetune_js_dt_scale` with a default value > 1.0 as joint space trajectories are
time optimal in sparse obstacle environments.
- Add note on deterministic behavior to website. Use lbfgs history < 12 for deterministic
optimization results.
- Add warning when adding a mesh with the same name as in existing cache.
- Remove warmup for batch motion gen reacher isaac sim example.
- Fix python examples in getting started webpage.
- Refactor warp mesh query kernels to use a `wp.func` for signed distance queries.
