 * Changes in upcoming Eglot
 
-** Diff previews of edits and new variable 'eglot-confirm-server-edits'
+
+* Changes in Eglot 1.16 (27/12/2023)
+
+** Code actions can be previewed in diff format
 
 The variable 'eglot-confirm-server-edits' replaces the obsolete
 'eglot-confirm-server-initiated-edits' and brings about a new
-confirmation model, making it possible to have only certain commands
-require user confirmation.  The type of confirmation has also been
-enhanced.  In particular it allows a temporary 'diff-mode' buffer to
-display the proposed changes, so the user can apply them one by one.

+** Completion sorting has been fixed
+
+In some situations, Eglot was not respecting the completion sort order
+decided by the language server, falling back on the sort order
+determined by the 'flex' completion style instead.  See github#1306.
+
+** Improve mouse invocation of code actions
+
+When invoking code actions by middle clicking with the mouse on
+Flymake diagnostics, it was often the case that Eglot didn't request
+code actions correctly and thus no actions were offered to the user.
+This has been fixed.  See github#1295.
 
 ** Optimized file-watching capability

-** Fixed "onTypeFormatting" feature
+** Faster, more accurate, event logging
+
+The Eglot events buffer takes advantage of new functionality in
+Jsonrpc 1.23.  By default, Lisp-style printing of JSON-RPC message (a
+common cause of performance degradation) is disabled.  The full
+original JSON message is presented instead.  See new variable
+'eglot-events-buffer-config', which replaces the obsolete
+'eglot-events-buffer-size'.
+
+** 'textdocument/onTypeFormatting' feature has been fixed
 
 For 'newline' commands, Eglot sometimes sent the wrong character code
-to the server.  Also made this feature less chatty in the mode-line
+to the server.  Also this feature is now less chatty in the mode-line
 and messages buffer.
 
-** Fixed completion sorting
+** Partial fix C-M-i "middle-of-symbol" completions (github#1339)
 
-In some situations, Eglot was not respecting the completion sort order

+** Add "Extending Eglot" section to manual
 
-** Improve mouse invocation of code actions
+** Fixed Elisp interface 'eglot-lsp-context' (github#1336, github#1337)
 
-When invoking code actions by middle clicking with the mouse on

+** Supports LSP's 'window/showRequest' (bug#62116)

+** The self-upgrade command is now called 'eglot-upgrade-eglot'
+
+** Newly added directories also watched (github#1228)
+
+** Send correct ':language-id' for JavaScript server (bug#67150)
+
+** New servers have been added to 'eglot-server-programs'.
