 # Hamiltonian Gauge Gravity Surveyor (HiGGS)
-## Version 1.0.0
+## Version 1.2.3
 
-- Initial release
+- **Feature:** abstract indices representing gauge-fixed theory given cleaner formatting with Gothic script, extended indices `a1`, `b1`, `c1` etc. denoted by primes.
+- **Feature:** provide more intuitive formatting of Poisson brackets in terms of smearing functions, as seen in output of `PoissonBracket` and `ViewTheory`.
+- **Patch:** fix shadowing error messages during the `Needs` or `Get` package call preamble.
+- **Patch:** fix [Issue #1](https://github.com/wevbarker/HiGGS/issues/1), loading of binaries on Windows.
+- **Patch:** fix errors produced by `PoissonBracket` with the option `"Surficial"->True`. This error follows from sign errors in line two of Equation (E3) in [2205.13534](https://arxiv.org/abs/2205.13534), and generates nonphysical surface terms. My particular thanks to [Manuel Hohmann](https://github.com/xenos1984) for identifying this.

 #### What are peta4 and appcg? 
 
 The files `./xAct/HiGGS/Documentation/Examples/peta4.*` and `./xAct/HiGGS/Documentation/Examples/appcg.*` refer to the jobs which implement the [HiGGS Commissioning Survey](https://wevbarker.com/higgs.html) and various unit tests. HiGGS does _not_ need these files to function. The names refer to two computing services:
