 # ggplot2 2.0.0.9000
 
-* `stat_bin_hex()` and `stat_bin_summary()` now use the same underlying 
-  algorithm so results are consistent (#1383). `stat_bin_hex()` now accepts
-  a `weight` aesthetic. To be consistent, the output variable from
-  `stat_bin_hex()` is now value instead of count.
+## New features
 
-* `facet_wrap()` correctly swaps `nrow` and `ncol` for facetting vertically
-  (#1417).
-
-* For geoms with both `colour` and `fill`, `alpha` once again only affects
-  fill (Reverts #1371, #1523). This was causing problems for people.
-
-* `geom_path()` knows that "solid" (not just 1) represents a solid line (#1534).
+* When mapping an aesthetic to a constant (e.g. 
+  `geom_smooth(aes(colour = "loess")))`), the default guide title is the name 
+  of the aesthetic, not the value (#1431).
 
-* `layer()` now automatically adds a `na.rm` parameter if none is explicitly
-  supplied.
+* `layer()` now accepts a function as the data argument. The function will be
+  applied to the data passed to the `ggplot()` function and must return a
+  data.frame (#1527). This is a more general implementation of the deprecated
+  `subset`.
 
 * `theme_update()` now uses the `+` operator instead of `%+replace%`, so that
   unspecified values will no longer be `NULL`ed out. `theme_replace()`
   preserves the old behaviour if desired (@oneillkza, #1519). 
 
-* `layer()` now accepts a function as the data argument. The function will be
-  applied to the data passed to the `ggplot()` function and must return a
-  data.frame (#1527).
-
-* `scale_size()` warns when used with categorical data.
-
-* `scale_size()`, `scale_colour()`, and `scale_fill()` gain date and date-time
-  variants (#1526).
-
-* `stat_function()` gains an `xlim` parameter (#1528).
-
-* `stat_summary()` preserves sorted x order which avoids artefacts when
-  display results with `geom_smooth()` (#1520).
-
-* All `geom_()` and `stat_()` function now have consistent argument order:
-  data + mapping, geom/stat/position, ..., specific arguments, common arguments
-  to all layers (#1305). This may break code if you were previously relying on
-  partial name matching, but in the long-term should make ggplot2 easier to 
-  use.
-
-* `stat_ecdf()` does a better job of adding padding to -Inf/Inf, and gains
-  an argument `pad` to suppress the padding if not needed (#1467).
-
-* `theme_void()` was completely void of text but facets and legends still
-  needed labels. They are now visible (@jiho).
-
-* Multipanel empty data is correctly plotted, rather than throwing an unhelpful 
-  error (#1445).
-
-* Eliminate spurious warning if you have a layer with no data and no aesthetics
-  (#1451).
-
-* `position = "nudge"` now works (although it doesn't do anything useful)
-  (#1428).
-
-* You can once again set legend key and height width to unit arithmetic
-  objects (like `2 * unit(1, "cm")`) (#1437).
-
-* When mapping an aesthetic to a constant (e.g. 
-  `geom_smooth(aes(colour = "loess")))`), the default guide title is the name 
-  of the aesthetic, not the value (#1431).
-
-* `ggsave("x.svg")` now uses svglite to produce the svg (#1432).
-
 * `stat_bin()` has been overhauled to use the same algorithm as ggvis, which 
   has been considerably improved thanks to the advice of Randy Prium (@rpruim).
