# What's Changed?
Short week, so a slightly shorter release! This one has been focused on
improving polish in fragment autocomplete and the new solver.
## New Type Solver
* Fix a bug where we didn't infer self types correctly under
bidirectional type inference.
* Improve the memory consumption of the new solver by reducing the
number of expensive allocations performed by `Substitution`.
* The New non strict Mode shouldn't issue errors when we call checked
functions with `never` values.
* Extend the number of cases in which the new non strict mode can report
unknown symbols.
* Fix a bug where `and` and `or` expressions didn't correctly forward
information computed by their operands. This should allow more programs
using these expressions to complete typechecking correctly.
* Small performance improvements for `Generalization`
## Fragment Autocomplete
* Fragment autocomplete provides richer autofill information when typing
`self.|`
* Fragment autocomplete now uses refinement information computed in the
new solver to provide more accurate incremental completion.
## Code Generation
* Fix a bug where Codegen could sometimes try to execute a
non-executable page
