OpenSSL 3.5
-----------
+### Changes between 3.5.2 and 3.5.3 [16 Sep 2025]
+
+ * Avoided a potential race condition introduced in 3.5.1, where
+ `OSSL_STORE_CTX` kept open during lookup while potentially being used
+ by multiple threads simultaneously, that could lead to potential crashes
+ when multiple concurrent TLS connections are served.
+
+ *Matt Caswell*
+
+ * The FIPS provider no longer performs a PCT on key import for RSA, DH,
+ and EC keys (that was introduced in 3.5.2), following the latest update
+ on that requirement in FIPS 140-3 IG 10.3.A additional comment 1.
+
+ *Dr Paul Dale*
+
+ * Secure memory allocation calls are no longer used for HMAC keys.
+
+ *Dr Paul Dale*
+
+ * `openssl req` no longer generates certificates with an empty extension list
+ when SKID/AKID are set to `none` during generation.
+
+ *David Benjamin*
+
+ * The man page date is now derived from the release date provided
+ in `VERSION.dat` and not the current date for the released builds.
+
+ *Enji Cooper*
+
+ * Hardened the provider implementation of the RSA public key "encrypt"
+ operation to add a missing check that the caller-indicated output buffer
+ size is at least as large as the byte count of the RSA modulus. The issue
+ was reported by Arash Ale Ebrahim from SYSPWN.
+
+ This operation is typically invoked via `EVP_PKEY_encrypt(3)`. Callers that
+ in fact provide a sufficiently large buffer, but fail to correctly indicate
+ its size may now encounter unexpected errors. In applications that attempt
+ RSA public encryption into a buffer that is too small, an out-of-bounds
+ write is now avoided and an error is reported instead.
+
+ *Viktor Dukhovni*
+
+ * Added FIPS 140-3 PCT on DH key generation.
+
+ *Nikola Pajkovsky*
+
+ * Fixed the synthesised `OPENSSL_VERSION_NUMBER`.
+
+ *Richard Levitte*
