+
+### Breaking Changes
+* Breaking Changes without explicit PR/issue numbers
+  Now the client SDK runs on Python 3.6, 3.7, and 3.8 and dropped support for Python 3.5.
+* All functional API classes are moved into the `ai.backend.client.func` sub-package.
+  [(#82)](https://github.com/lablup/backend.ai-client-py/issues/82)
+  - `Kernel` is changed to `Session`.
+  - The session ID field name in the response of `Session` objects
+    is now `session_id` instead of `kernel_id`.
+  - Except above, this would not introduce big changes in the SDK user
+    codes since they use `AsyncSession` and `Session` in the
+    `ai.backend.client.session` module.
+
+### Features
+* Features without explicit PR/issue numbers
+  - Add SDK API (`SessionTemplate`) and CLI command set (`backend.ai sesstpl`)
+* Support for unmanaged vfolders and token-based download API
+  [(#77)](https://github.com/lablup/backend.ai-client-py/issues/77)

+* Add `--format` and `--plain` options to `backend.ai ps` command to customize the output table format
+  [(#80)](https://github.com/lablup/backend.ai-client-py/issues/80)
+* Perform automatic API version negotiation when entering session contexts while keeping the functional API same
+  [(#82)](https://github.com/lablup/backend.ai-client-py/issues/82)
+* Support dotfiles management API and CLI
+  [(#85)](https://github.com/lablup/backend.ai-client-py/issues/85)
