+
+  * Improve readability of the Travis job log (Daniel Thayer)
+
+  * Fix tracking of DCE-RPC context identifier mappings
+
+    This adds previously-missing support for "Alter Context"
+    request/response PDUs (initial patch contributed by Mark Fernandez).
+
+    Also, context ID arguments were added to dce_rpc_bind, dce_rpc_request,
+    and dce_rpc_response in order to properly track what endpoint/operation
+    a given opnum maps to. (Jon Siwek, Corelight)
+
+2.5-897 | 2018-08-23 15:53:16 +0000
+
+ * BIT-1885: Fix input framework memory leak. For input threads that
+   get joined during run-time, messages could remain in the thread's
+   queue and leak. (Jon Siwek, Corelight)
+
+ * Increase timeout for a memleak test. (Jon Siwek, Corelight)

+
+  * Fix outdated documentation test baselines (Jon Siwek, Corelight)
+
+  * Add 'smtp_excessive_pending_cmds' weird (Jon Siwek, Corelight)
+
+  * Fix SMTP command string comparisons (Jon Siwek, Corelight)
+
+  * Improve handling of empty lines in several text protocol analyzers
+    (Jon Siwek, Corelight)
+
+  * Add rate-limiting sampling mechanism for weird events
+
+    The generation of weird events, by default, are now rate-limited
+    according to these tunable options:
+
+      - Weird::sampling_whitelist
+      - Weird::sampling_threshold
+      - Weird::sampling_rate
+      - Weird::sampling_duration
+
+    The new get_reporter_stats() BIF also allows one to query the
+    total number of weirds generated (pre-sampling) which the new
+    policy/misc/weird-stats.bro script uses periodically to populate
+    a weird_stats.log.
+
+    There's also new reporter BIFs to allow generating weirds from the
+    script-layer such that they go through the same, internal
+    rate-limiting/sampling mechanisms:
+
+      - Reporter::conn_weird
+      - Reporter::flow_weird
+      - Reporter::net_weird
+
+    Some of the code was adapted from previous work by Johanna Amann.
+    (Jon Siwek, Corelight)
+
+  * Teach timestamp canonifier about timestamps before ~2001
+    (Jon Siwek, Corelight)
+
+2.5-877 | 2018-08-20 14:58:58 -0500

+  * Remove the node-specific local-*.bro scripts (Daniel Thayer)
+
 2.5-875 | 2018-08-20 12:45:32 -0500
 
   * Improve diff-remove-abspath canonifier: collapse '/' sequences
