 # superspreading (development version)
 
+The third minor release of the _superspreading_ package contains enhancements to several functions and a new vignette. 
+
+We are also pleased to welcome Dillon Adam (@dcadam) as a new package author for his contributions towards this version.
+
+## New features
+
+* The `proportion_transmission()` function has been expanded to incorporate a new method. The new method calculates the proportion of transmission from X% the most infectious individuals, corresponding to the [Lloyd-Smith et al. (2005)](https://doi.org/10.1038%2Fnature04153) calculation. The `proportion_transmission()` has a new `method` argument to toggle between the two calculations (@dcadam, #99).
+* A new vignette explaining the methods in the `proportion_transmission()` function (#101). 
+* {bpmodels} is removed as a package dependency and a branching process simulation function, modified from `bpmodels::chain_sim()`, is added to the {superspreading} package (#103). @sbfnk is added as copyright holder and @jamesmbaazam as a contributor.
+* `probability_contain()` is enhanced to enable to probability of containment within a certain amount of time since the outbreak started. This adds `outbreak_time` and `generation_time` arguments to `probability_contain()`. This addition is backwards compatible as by default the time is unlimited, `outbreak_time = Inf`, and no generation time is required.
+
+## Breaking changes
+
+* The `stochastic` argument in `probability_contain()` has been renamed `simulate` to be consistent with other functions (#103).
+
+## Minor changes
+
+* The proportions output of `proportion_*()` functions are now formatted to significant figures rather than rounding to prevent small values being rounded to zero (#102).
+* Improve input checking, error messages and edge case handling for functions (#102).
+* Vignettes now use `rmarkdown::html_vignette` instead of `bookdown::html_vignette2` and `as_is: true` has been removed due to changes to {pkgdown} in v2.1.0. {bookdown} has been removed as a suggested package and code folding is removed from vignettes.
+* The `get_epidist_params()` internal function has been renamed `get_epiparameter_params()` since {epiparameter} renamed the `<epidist>` class to `<epiparameter>` (#100).
+
+## Bug fixes
+
+* None to {superspreading} functions.
+* Update {epiparameter} use in vignette and tests (#106).
+
+## Deprecated and defunct
+
+* None
+
 # superspreading 0.2.0
