+Compatibility Concerns
+
+[#19209](https://github.com/apache/nuttx/pull/19209) !boards/nsh: Replace TEA
password storage with PBKDF2-HMAC-SHA256 hashing
+
+Replace reversible TEA password storage in /etc/passwd with one-way
PBKDF2-HMAC-SHA256 hashing in modular crypt format (MCF):
+$pbkdf2-sha256$<iterations>$<base64url-salt>$<base64url-hash>
+
+BREAKING CHANGE: TEA-encoded /etc/passwd entries no longer verify.
+Regenerate with tools/mkpasswd or NSH passwd/useradd after upgrading
nuttx-apps.
+
+Changes:
+
+ Add apps/crypto/pbkdf2 (PBKDF2-HMAC-SHA256; Mbed TLS backend when
available, self-contained SHA-256 fallback otherwise)
+ Rewrite passwd_encrypt.c / passwd_verify.c to use PBKDF2 and
timingsafe_bcmp() for verification
+ Add shared passwd_base64.c for base64url encode/decode
+ Enforce password complexity when setting passwords (min 8 chars, upper,
lower, digit, special character)
+ Add testing/pbkdf2 (RFC 6070 vectors + passwd round-trip test)

+
+
+[#19297](https://github.com/apache/nuttx/pull/19297) !arch/arm/src/stm32:
unify the timer input clock board options
+
+Replace the divergent board conventions for the timer input clock frequency
with a single uniform convention provided by every board:
+
+ STM32_APBx_TIMn_CLKIN and BOARD_TIMn_FREQUENCY -> STM32_TIMn_CLKIN
+ STM32_APBx_LPTIMn_CLKIN, BOARD_LPTIMn_FREQUENCY and STM32_LPTIMn_FREQUENCY
-> STM32_LPTIMn_CLKIN
+
+All STM32 consumers (tim/lptim/pwm/adc/dac/capture/sdadc/dfsdm/pulsecount)
updated to match; the timer input clock is now bus-agnostic
+in the drivers.
+
+Boards that carried the same timer clock in more than one convention now
define STM32_TIMn_CLKIN exactly once, derived from the APB bus
+clock (PCLKx with the x2 doubler when the APB prescaler is greater than 1),
instead of redefining it with a second, sometimes different, value.
+
+BREAKING CHANGE: The timer input-clock board macros STM32_APBx_TIMn_CLKIN,
BOARD_TIMn_FREQUENCY, STM32_APBx_LPTIMn_CLKIN, BOARD_LPTIMn_FREQUENCY
+and STM32_LPTIMn_FREQUENCY are removed in favor of STM32_TIMn_CLKIN and
STM32_LPTIMn_CLKIN.
+Out-of-tree boards must define STM32_TIMn_CLKIN / STM32_LPTIMn_CLKIN (drop the
APB bus from the name, keep the value),
+and out-of-tree drivers referencing the old names must be updated.
+
+
+[#19321](https://github.com/apache/nuttx/pull/19321) !boards: enforce secure
ROMFS passwd and TEA key setup
+
+Remove implicit default credentials and add build-time validation. Add
check_passwd_keys.sh and gen_passwd_keys.sh; run key setup via passwd_keys.mk
+ before config.h is generated. Mirror the same logic in
cmake/nuttx_add_romfs.cmake for CMake builds.
+
+BREAKING CHANGE: Builds with CONFIG_BOARD_ETC_ROMFS_PASSWD_ENABLE=y now
require an explicit admin password and non-default TEA keys.
+The Kconfig default password "Administrator" and default TEA keys are no
longer accepted. Fix: run make menuconfig, set Admin password under
+Board Selection -> Auto-generate /etc/passwd, enable random TEA keys or
+set CONFIG_FSUTILS_PASSWD_KEY1..4 manually, and use NSH login with Encrypted
password file verification.
