+* [0.2.7](https://github.com/mwiede/jsch/releases/tag/jsch-0.2.7)
+  * Fix exception logging in Log4j2Logger.
+  * [#265](https://github.com/mwiede/jsch/issues/265) change buffer_margin computation to be dynamic based upon the MAC to allow connections that advertise small maximum packet sizes.
+  * [#266](https://github.com/mwiede/jsch/issues/266) fix PuTTY key parsing to work with unix line endings.
+  * Add support for ECDSA & EdDSA type PuTTY keys.
+  * [#71](https://github.com/mwiede/jsch/issues/71) add support for PuTTY version 3 format keys.
+    * Encrypted PuTTY version 3 format keys requires [Bouncy Castle](https://www.bouncycastle.org/java.html) (bcprov-jdk18on).
+  * Eliminate KeyPairDeferred and instead change handling of OpenSSH V1 type keys to be more like other KeyPair types.
+  * Be more vigilant about clearing private key data.
+  * Improve PKCS8 key handling and add support for PKCS5 2.1 encryption.
+  * Add support for ECDSA type PKCS8 keys.
+  * Add support for SCrypt type KDF for PKCS8 keys.
+    * PKCS8 keys using SCrypt requires [Bouncy Castle](https://www.bouncycastle.org/java.html) (bcprov-jdk18on).
+  * Add support for EdDSA type PKCS8 keys.
+    * EdDSA type PKCS8 keys requires [Bouncy Castle](https://www.bouncycastle.org/java.html) (bcprov-jdk18on).
+  * Attempt to authenticate using other signature algorithms supported by the same public key.
+    * Allow this behavior to be disabled via `try_additional_pubkey_algorithms` config option.
+      * Some servers incorrectly respond with `SSH_MSG_USERAUTH_PK_OK` to an initial auth query that they don't actually support for RSA keys.
+  * Add a new config option `enable_pubkey_auth_query` to allow skipping auth queries and proceed directly to attempting full `SSH_MSG_USERAUTH_REQUEST`'s.
+  * Add a new config option `enable_auth_none` to control whether an initial auth request for the method `none` is sent to detect all supported auth methods available on the server.
 * [0.2.6](https://github.com/mwiede/jsch/releases/tag/jsch-0.2.6)
   * Include host alias instead of the real host in messages and exceptions by @ShadelessFox in https://github.com/mwiede/jsch/pull/257
   * Fix missing keySize set when loading V1 RSA keys by @Alex-Vol-Amz in https://github.com/mwiede/jsch/pull/258
