To avoid hinting whether your volumes contain a hidden volume or not, or if you depend on plausible deniability when using hidden volumes/OS, then you must recreate both the outer and hidden volumes including system encryption and hidden OS, discarding existing volumes created prior to 1.18a version of VeraCrypt.
+1.26.21 (May 12th , 2025):
+
+All OSes:
+
+ Add support for the Chinese encryption algorithm SM4.
+ Fix whirlpool implementation for big-endian platforms (GH #1529).
+ Rename "Dismount All" to "Unmount All" in UI. Use ALT+u as new accelerator key instead of ALT+s
+ Add contributed Chinese and Russian CHM documentation.
+ Update translations.
+
+Windows:
+
+ Update libzip to version 1.11.3.
+
+Linux:
+
+ Add support for AppImage packaging and usage.
+ Fix absolute path of 'true' command not being used when checking if sudo session is active.
+ Fix failure to use Hungarian language translations.
+ Improve generic installer scripts (GH #1514).
+ Add support for /run/media/veracrypt as default mount prefix when /media is not available(GH #1524).
+ Remove pcsclite dependency from .deb/.rpm packages since it is detected/loaded dynamically at runtime.
