+# v4.0.0.dev9 (2021-04-22)
+
+## Features
+
+### Core
+
+- A new `SET_CONFIG` command can be used to change the configuration with a stroke, e.g.:
+  ``` json
+  "O*EP": "{PLOVER:SET_CONFIG:'translation_frame_opacity':100}",
+  "TR*PB": "{PLOVER:SET_CONFIG:'translation_frame_opacity':0}",
+  ```
+  to change the opacity of the "Add Translation" dialog on the fly. (#989)
+- Speed up loading dictionaries. (#1022)
+- Be more restrictive with macro names: only accept valid identifier, so for example `==` is not handled like a macro anymore. (#1025)
+- Ignore case when processing builtin commands / metas. (#1069)
+- Add user friendly names for built-in metas, e.g.: `{:retro_case:cap_first_word}`, `{:retro_currency:$c}`, `{:attach:attach^}`, etc... (#1069)
+- Improve orthography rules. (#1092, #1212)
+- The configuration is now automatically saved on change, rather than on exit. (#1123)
+- Add prefix strokes (syntax `/STROKE`) that will only translate if they are at the beginning of a word. Word endings can be specified with `{:word_end}` or `{$}`. (#1157)
+- Add support for conditional formatting (based on the text following a translation): `{=REGEXP/TRANSLATION_IF_FOLLOWING_TEXT_MATCH/TRANSLATION_IF_NOT}` or `{:if_next_matches:REGEXP/TRANSLATION_IF_FOLLOWING_TEXT_MATCH/TRANSLATION_IF_NOT}`. (#1158)
+
+### User Interface
+
+- Add menu entry for opening the configuration directory ("File" => "Open config folder"). (#981)
+- Automatically focus the input field and pre-select the previous input when the lookup window is activated. (#1009)
+- Improve the configuration dialog for serial machines: automatically scan available ports and default to the first one. (#1036)
+- The "Add translation" stroke lookup now returns entries for all enabled dictionaries and is debounced to improve performance. (#1084)
+- Added translation into Spanish. (#1165)
+- A new command, `{PLOVER:SUGGESTIONS}`, is available to open the suggestions window with a steno stroke. (#1184)
+- Add support for saving dictionaries:
+  - save a copy of each selected dictionary
+  - merge the selected dictionaries into a new one
+  - both operations support converting to another format (#1244)
+- Added translation into Dutch. (#1264)
+- Added Italian translation. (#1268)
+
+### Linux
+
+- The distribution Python is now built with optimization. (#1068)
+- Expand the list of supported key names in key combos to include non-US specific keys (like `ISO_Level3_Shift`). (#1082)
+- The default configuration directory on Linux is now `~/.config/plover` (`~/.local/share/plover` is still supported for backward compatibility). (#1123)
+
+### macOS
+
+- The minimum version supported by the macOS bundle is now 10.13 (High Sierra). (#1156)
+
+### Windows
+
+- The distribution is now 64bits. (#1023)
+
+## Bugfixes
+
+### Core
+
+- Fix retrospective insert space macro when the previous translation involved suffix keys. (#995)
+- Fix updating a dictionary mapping: ensure reverse lookups data stays consistent. (#1022)
+- Fix keymap validation: properly fallback to default keymap when invalid. (#1065)
+- Fix lookups by translation: do not ignore lower priority dictionaries when a match is found in a higher priority one. (#1066)
+- Fix wordlist support for system plugins: try loading from the system dictionaries root (and not Plover assets directory). (#1116)
+- Configuration save operations are now atomic. (#1123)
+- Fix forced lowercasing of all engine command arguments. (#1139)
+- Fix implicit hyphen handling with numbers only strokes on some theories (e.g. Melani). (#1159)
+- Fix unbounded memory use in the lookup functions used by the Suggestions window. (#1188)
+
+### Dictionaries
+
+- Fix a number of invalid entries in the main dictionary. (#1038)
+- Tweak orthographic rules so "reduce/{^ability}" result in "reducibility" instead of "reducability". (#1096)
+
+### User Interface
+
+- Fix a possible crash on close when opening a read-only dictionary in the editor. (#897)
+- Fix possible crash when changing machine parameters in the configuration dialog. (#1041)
+- Fix internationalization of machine types in the configuration dialog. (#1061)
+- Fix tools shortcuts. (#1062)
+- Fix crashes due to GUI exceptions reaching the event loop. (#1135)
+- Fix an exception caused by an incorrect assertion that would prevent enabling and disabling extension plugins if they weren't on the first row. (#1171)
+- Fix changes to the list of enabled extension plugins not being saved to the configuration file. (#1230)
+- Fix missing translations. (#1248)
+
+### Linux
+
+- Fix output capitalization issue. (#1153)
+- Fix a race condition that may freeze Plover while toggling with keyboard input machine. (#1163)
+
+### macOS
+
+- Fix an issue where permissions had to be granted to "env" on macOS Catalina 10.15. (#1152)
+- Mac notifications no longer have "Plover" as their title. (#1271)
+
+### Windows
+
+- Fix Unicode characters output. (#991)
+- Fix installer's icon. (#1027)
+
+## API
+
+### Breaking Changes
+
+- `StenoDictionaryCollection.casereverse_lookup` now returns a `set` (instead of a `list`). (#1066)
+- The API for providing i18n support as been changed: see `doc/i18n.md` for more information. (#1258)
+
+### New
+
+- `plover_build_utils.setup` now provides a new `babel_options` helper for configuring Babel for i18n support. (#1258)
+
+
 # v4.0.0.dev8+66.g685bd33 (2018-07-02)
