v0.14.2

Bug fixes:

• A channel variable whose value the log buffer cut mid-write no longer ends
  there. Reassembly runs past the cut and stops at the next variable or field
  name, so the rest of a multi-line value — an SDP part inside sip_multipart,
  a long SIP header — is recovered instead of being reported line by line as
  unreadable. The value is still flagged as cut, since its middle is lost.
