 # fish 2.5b1 (released ???)
 
 ## Significant changes
-- fish now requires C++11 to build.
-- The `random` command has added features, including the possibility to add start, stop and step values
-  and the `choice` subcommand to pick an argument from a list (#3619).
+- fish now requires C++11 to build. GCC's g++ 4.8 or later, or LLVM's clang 3.3 or later, are known to work. Older platforms may require a newer compiler installed.
+- Attempting to exit with running processes in the background produces a warning, then signals them to terminate if a second attempt to terminate them is made. This brings the behaviour for running background processes into line with stopped processes. (#3497)
+- The `random` command can now have start, stop and step values specified, or the new `choice` subcommand can be used to pick an argument from a list (#3619).
 - The `test` command now prints errors for numeric operations on invalid integers (#3346, #3581).
 - List indexes are handled better, and a bit more liberally in some cases (`echo $PATH[1 .. 3]` is now valid) (#3579).
 - `function` now errors out if passed invalid flags (#3574).

 - The `help` command now reads the $fish_help_browser variable (#3131).
 
 ## Notable fixes and improvements
-- `complete` no longer prints errors when given an empty string as a description (#3557).
-- Abbreviations can now be renamed with `abbr -r OLD_KEY NEW_KEY` (#3610).
-- $status is now set to 123 when a syntactically invalid command is entered (#3616).
+- `complete` accepts empty strings as descriptions (#3557).
+- Abbreviations can now be renamed with `abbr --rename OLD_KEY NEW_KEY` (#3610).
+- The `$status` variable is now set to 123 when a syntactically invalid command is entered (#3616).
 - The `status` command now accepts subcommands like `status is-interactive`. The old forms continue to be supported for the foreseeable future (#3526).
 - A new `prompt_hostname` function which prints a hostname suitable for use in prompts (#3482).
 - A new function `edit_command_buffer` (bound to alt-e/alt-v by default) to edit the command buffer in $EDITOR (#3627).
