[partition] Log partition-model lookup failures

+# 3.2.50 (unreleased) #
+
+This release contains contributions from (alphabetically by first name):
+ - Erik Dubois
+
+## Core ##
+ - No core changes yet
+
+## Modules ##
+ - *networkcfg* could fail to update the NetworkManager configuration
+   if the SSID or username contained non-ASCII characters **and** the
+   default Python text-file encoding was set to ASCII. The files are
+   now read and written in UTF-8, explicitly. #1848
+ - *preservefiles* was missing some necessary features, needed for it
+   to replace the deprecated log-file-saving functionality in the *umount*
+   module. (Thanks Erik and Joe for testing) #1851
+
+
+# 3.2.49.1 (2021-12-11) #
+
+This is a hot-fix release, to fix a regression in the calculation of
+swap-size. Reported by EndeavourOS (Joe Kamprad) and Xero Linux.
+
+
+# 3.2.49 (2021-12-10) #
+
+This release contains contributions from (alphabetically by first name):
+ - Artem Grinev
+ - Evan James
+
+Distributions are **specifically** reminded to update the *umount* module
+configuration (and to use *preservefiles* if needed).
+
+## Core ##
+ - Errors (e.g. when an installation fails for whatever reason) are displayed
+   in a dialog with a scrollable details panel, rather than growing up
+   to the size of the screen. (Thanks Artem)
+
+## Modules ##
+ - *bootloader* better supports multiple installations of the same OS.
+ - *mount* supports btrfs subvolumes on subdirectories of / now.
+ - *partition* now supports "deep" btrfs subvolume names, e.g. a
+   separate subvolume for `/usr/local`. (Thanks Evan)
+ - The *umount* module now warns if the "preserve log file" feature is used.
+   This has been deprecated for a long time: use the *preservefiles* module
+   instead. A future release will turn this into an error.

 #     where <mode> is in octal (e.g. 4777 for wide-open, 0400 for read-only
