Symbolica

**Notable changes**
- Tensor dummy index symmetrization
- Graph canonization, with support for directed edges and vertex and edge colours
- Add support for cyclesymmetric functions
- ASM support for x86_64 Mac

**Notable changes**
- Optimized nested expression evaluation with C++ and ASM output modes
- Seamlessly load compiled evaluation library
- Add cycle-symmetrization transformer
- Improve Rust ergonomics

**Notable changes**
- Support for floating point coefficients, parsing of floats in standard and exp-notation
- Precision tracking floating point numbers
- Galois fields (also in Python API)
- Factorization of polynomials over Galois fields and algebraic numbers
- Extension of algebraic numbers, e.g. joining `sqrt(2)` and `sqrt(3)`
- Linearization transformer

**License changes**
- Non-commercial users are now allowed to run Symbolica on one core and instance per device for **free** without requiring a sign-up
- License keys will now work offline. Remember to [update the key](https://symbolica.io/docs/get_started.html#updating-the-key)!

**Notable changes**
- Multiprecision floats can be used for evaluations
- Introduce error propagating float
- Series can now be constructed using a relative depth

**Upgrade notice**
- Offline keys have been deprecated
- `rug::Float` does not implement `Real` anymore. Use `.into()` to convert to the wrapper type `Float` that does operations that do not lose precision (see [here](https://gitlab.com/tspiteri/rug/-/issues/64))

**Notable changes**
- Multiple replacements at the same time (see [here](https://reform.zulipchat.com/#narrow/stream/392700-functionality/topic/pattern.20matching/near/439537480))
- `cancel` function that cancels common factors between numerators and denominators
- Arithmetical operator overloading for series and atoms
- Square brackets will be parsed as parentheses for functions

**Upgrade note**
- The `coefficient_list` function now handles multivariate polynomials and therefore its signature has changed

**Notable changes**
- Puiseux series expansion support with additional support for `log(x)`
- Term streaming for very large expressions
- Import/export of expressions and state (Rust only for now)
- Option to expand in particular variable

**Upgrade note**
- Define variables and symbols in Python API using `symbol`/`symbols`, instead of `var`/`vars`/,`fun`/`funs`
- Expressions are now callable and a function is created if the expression is a variable (see [**api>python**](https://reform.zulipchat.com/#narrow/stream/363562-api/topic/python/near/434938578) )
