Library updates: mbedTLS : 1.3.16.

1.0.5 | Sep 15, 2014

Fixed Import Profiles bug that affects 1.0.4 on iOS 8. This issue causes OpenVPN to fail to detect new profiles that are available for import.
Support new iOS 8 feature where Settings App can be used to launch native OpenVPN profiles. Note that only autologin profiles (i.e. profiles that don't require credential entry) can be launched using this mechanism.
Added "Seamless Tunnel" setting (See OpenVPN section of Settings App) for iOS 8 and higher. Make a best-effort to keep the VPN tunnel active during pause, resume, and reconnect states to minimize the likelihood of packet leakage during sleep/wakeup and network reconfiguration events.
Connection speed improvements.
Support OpenVPN "float" directive.
Don't fail the connection when OpenVPN "topology net30" directive is mixed with "ifconfig-ipv6", since the topology setting doesn't really affect IPv6.
Recognize backslash as a directory separator, to allow import of Windows profiles.
Library updates: PolarSSL : 1.3.8 Boost : 1.56.0.

1.0.4 | Jan 29, 2014

Added "Force AES-CBC ciphersuites" setting to revert to SSL/TLS negotiation strategy used in OpenVPN Connect 1.0.0 and 1.0.1. This option constrains the OpenVPN TLS negotiation to one of two standard AES-CBC ciphersuites and is provided as a compatibility option when connecting to servers that use legacy SSL implementations.
Known issue: Automatic reconnect/wakeup onto cellular data doesn't work with iOS 7.0.x. A fix is expected in iOS 7.1.
Known issue: IPv6 tunnel routes may not be added to the routing table on iOS 7. Workaround: use redirect-gateway instead of pushing specific IPv6 routes. For example, from the server: push "redirect-gateway ipv6" or client: redirect-gateway ipv6.

Note: iOS 7 requires that if redirect-gateway is used, that it is used for both IPv4 and IPv6 as the above directive accomplishes.

Added support for "http-proxy" and "http-proxy-option" directives in the profile. Note that these directives are currently only supported in the main profile, outside of blocks. Also note that proxy settings in the Settings app under OpenVPN always have priority over proxy directives given in the profile.
Worked around an issue where connect slider control was sending repeating ON/OFF messages to the app. This could potentially cause connection failures where the connect slider control would move into the ON position, the credentials fields would be cleared, but no connection would occur, or the connection slider would freeze in the OFF position.
iOS 7 allows OpenVPN VPN-On-Demand (VoD) profiles to be connected and disconnected using the Settings App.
Allow "Certificate" field in UI to remain unselected for profiles that connect without a client certificate.
Re-added support for DES-CBC cipher that was inadvertently dropped in 1.0.2 (Note: DES-CBC is an obsolete, insecure cipher that should no longer be used. It is provided only for compatibility with legacy systems).
Added additional PKCS#1 signature methods. This may fix an issue where the following error is seen in the log: "PolarSSLContext::epki_sign unrecognized parameters, mode=1 hash_id=11 hashlen=32".
Added new OpenVPN Setting "Network state detection" that allows control over how OpenVPN handles network state changes. For more info, see app Help FAQ under the section "What is the meaning of the various OpenVPN settings in the iOS Settings App?"
Support iOS .mobileconfig profiles that contain standard OpenVPN profiles (previously only VPN-On-Demand .mobileconfig profiles were supported). See app Help for detailed instructions on how to create an OpenVPN .mobileconfig profile.
Allow importing of profiles via iTunes where auth-user-pass directive references an external creds file.
Added LZ4 compression support.
Report client app name/version to server via IV_GUI_VER parameter.

1.0.3 | Dec 24, 2013

Raised minimum required iOS version to 6.1 (iOS 5.1.1 installer will not install Connect, and will delete previous working 1.0.1 install).

1.0.2 | Dec 16, 2013

Added support for ARM-64 including iPhone 5s and iPad Air.
Allow password to be saved for static challenge/response profiles.
Resolved the issue where iOS plugin was not able to fully enumerate the cert chain from Keychain Identities. Note that this solution is still not ideal because the iOS keychain appears unable to import a PKCS#12 file as a bundle. It only imports the leaf cert/key and ignores the rest. So for this fix to be effective, each of the root and intermediate certs in the PKCS#12 file must be manually extracted and separately imported as .crt files.
Added the capability for server to push proxy options, e.g.:

push "dhcp-option PROXY_HTTP 10.144.5.14 3128"

push "dhcp-option PROXY_HTTPS 10.144.5.14 3128"

push "dhcp-option PROXY_BYPASS VPN Software Solutions & Services For Business | OpenVPN VPN Software Solutions & Services For Business | OpenVPN "

push "dhcp-option PROXY_AUTO_CONFIG_URL http://www.openvpn.net/proxy.pac"

Note: this is a separate and distinct feature from the one to connect through an HTTP proxy. This feature allows proxy options to be set for Safari (and possibly other apps as well) for the duration of the VPN session.

These options can be placed directly in the profile, i.e.

--> dhcp-option PROXY_HTTP 10.144.5.14 3128

or pushed by the server:

--> push "dhcp-option PROXY_HTTP 10.144.5.14 3128"

Updated PolarSSL to 1.2.10. This version of PolarSSL adds support for PKCS#8 private keys.
Fixed issue where some pushed options were incorrectly persisting across reconnections.
Fixed core bug that could cause reconnected TCP sessions to lock up with repeating replay errors.
Fixed core bug where server-pushed keepalive parms (ping, ping-restart) would be ignored.
"Session invalidated" errors will now explicitly reference a reason code.
Implemented "client-cert-not-required" directive as an alias for "setenv CLIENT_CERT 0".
Added core support for tun-mtu directive.
Fixed options parsing issue if non-aggregate option was specified in profile as well as pushed by server (the pushed version should win).
Implemented "inactive" directive.
Relax options parser somewhat and follow OpenVPN 2.x behavior where if more than one instance of an option exists, and a single instance of the option is required, use the last instance. Previously we would raise an exception in this case.
Added tls-version-min directive, to require server to support a minimum TLS version. For example,

--> tls-version-min 1.2 would require TLS 1.2 or higher for connection with the server. The connection would fail if the server cannot meet this requirement.

Support "setenv opt" prefix before directives, where its presence indicates that the directive is optional, i.e. if a client doesn't understand the directive, it should simply ignore it.
Log unused options, i.e. options specified in config file that were unrecognized, ignored, or unused.

This behavior is somewhat different (by design) to 2.x branch, which will raise a fatal exception if an unrecognized option is encountered.

1.0.1 | May 20, 2013

Fixed proxy error "NTLM phase-2 Content-Length is not zero".
Updated PolarSSL to 1.1.6.
Implemented "tls-remote", "route-nopull", "remote-random", "cipher none", and "auth none" directives.
Support DNS names that resolve to multiple addresses by trying each address in sequence.
At Apple's request, require one-time user confirmation before starting initial VPN connection.
Log invalid server-pushed routes or dhcp-options but don't disconnect.
As device moves between WiFi and cellular networks, proactively reconnect.
Raise an error when unsupported modes are used, such as static key mode.
Support "tcp-client" usage such as this: remote foo.bar 1194 tcp-client
Client will report its protocol as UDPv4 or TCPv4_CLIENT in options compatibility string even if running over IPv6 transport to maintain compatibility with OpenVPN 2.x branch.
Support client profiles that use Windows UTF-8 BOM.
Added "Reconnect on wakeup" preference (on by default).
The "key-direction" default has been changed to "bidirectional" for compatibility with OpenVPN 2.x branch, however the previous default ("1") will be retained for profiles imported with 1.0.0 to avoid breakage. Note, however, that the previous default cannot be retained for previously imported VPN-on-Demand profiles, which could potentially fail to connect if they don't declare a key-direction key/value pair on the assumption that it defaults to "1". The solution is to explicitly declare key-direction in VPN-on-Demand profiles if the OpenVPN configuration file they are derived from declares it as well.
Fixed bug where pushed ifconfig subnet was not routing into the tunnel.
When split-tunnel VPN configuration is used (i.e. not redirect-gateway), and at least one pushed DNS server is present: (a) route all DNS requests through pushed DNS server if no added search domains, or (b) route DNS requests for only specifically added search domains if at least one added search domain.
Fixed bug where app would crash on startup if device keychain had certificate with nil subjectSummary.
Fixed issue where "reneg-sec 0" was causing an infinite reconnect loop.
Don't add IPv4 or v6 routes if the ifconfig for the particular IP protocol is absent.
Added support for "net_gateway" as a route destination. This effectively excludes the route from the tunnel.
Allow clients to connect without a client certificate or key, if the server allows it, and if the client profile contains the following directive: setenv CLIENT_CERT 0
Allow "dhcp-option DOMAIN …" directives to be pushed with multiple space-separated domains.
Fixed an issue that prevented an External Certificate profile from also being an Autologin profile.
Fixed a corner case where profiles with saved passwords that connect to a server that uses Session ID tokens (such as an Access Server) would fail to automatically reconnect after long pause periods, such as when the device is asleep.
Add "OS Event" logging to OpenVPN log file, including: (a) network available/unavailable and (b) sleep/wakeup.
