Release Notes: A malloc() buffer overrun was resolved, so that SSL/TLS certificate information is now always reported properly. The IMAP client no longer skips messages if fetchmail's "idle" is in use. The SMTP client now recovers from errors when sending an RSET command. Several other IMAP improvements were made. A FreeBSD build warning was resolved. Documentation was improved.
Release Notes: This release fixes a few minor bugs, improves OpenSSL error reporting, and adds an Esperanto translation.
Release Notes: Compilation with OpenSSL implementations before 0.9.8m lacking SSL_CTX_clear_options() works again, but is neither supported nor recommended. The combination of "--plugin" and "-f -" was fixed. Logfile vs. syslog handling was cleaned up. Other minor changes were made.
Release Notes: A security issue where a misinterpreted server response could allow DoS and data theft in NTLM authentication was fixed. This issue was reported as CVE-2012-3482. The false disabling of a countermeasure against plaintext attacks in block ciphers was fixed. Various other minor fixes were made.
Release Notes: A NUL byte insertion bug in the IMAP client, which occurred when the last line of the input had no LF and no CRLF termination, was fixed.
Release Notes: This release fixes a STARTTLS denial of service vulnerability (CVE-2011-1947). It reduces repetitions in "unseen" message logging and speeds up IMAP fetches with full mailboxes quite a bit. Fetchmail now sets its Internet sockets to keepalive mode, to detect disconnections, and resolves MD5-related build problems.
