+Version 1.1.13 (2020-06-06)
+---------------------------
+
+Compatibility notes:
+
+- When upgrading from borg 1.0.x to 1.1.x, please note:
+
+  - read all the compatibility notes for 1.1.0*, starting from 1.1.0b1.
+  - borg upgrade: you do not need to and you also should not run it.
+  - borg might ask some security-related questions once after upgrading.
+    You can answer them either manually or via environment variable.
+    One known case is if you use unencrypted repositories, then it will ask
+    about a unknown unencrypted repository one time.
+  - your first backup with 1.1.x might be significantly slower (it might
+    completely read, chunk, hash a lot files) - this is due to the
+    --files-cache mode change (and happens every time you change mode).
+    You can avoid the one-time slowdown by using the pre-1.1.0rc4-compatible
+    mode (but that is less safe for detecting changed files than the default).
+    See the --files-cache docs for details.
+- 1.1.11 removes WSL autodetection (Windows 10 Subsystem for Linux).
+  If WSL still has a problem with sync_file_range, you need to set
+  BORG_WORKAROUNDS=basesyncfile in the borg process environment to
+  work around the WSL issue.
+
+Fixes:
+
+- rebuilt using a current Cython version, compatible with python 3.8, #5214
