  • Trial keys are no longer registered with our backend server.
  • The unregister process will now ignore errors returned by the backend server.
  • Improved the performance of executing shell tasks that required reading back output from the task.
  • Updated the Full Disk Access assistant to present different steps on macOS Ventura and newer, accounting for the slight changes in the User Interface of System Settings on modern macOS.
  • Updated the uninstaller’s unregister process result codes.
  • Updated OLH (which was neglected for several revisions).
  • Updated hard coded links to our website now use https instead of http.
BUG FIXES:
  • Fixed a bug whereby wrong system information was being passed when trying to register the app.

  • Trimmed the amount of log messages being generated in the Release build.

2.2.3 - March 8th, 2023
BUG FIXES:
  • Fixed a problem that could could cause changes to a volume’s “Ignore Ownership” setting to fail.

2.2.2 - November 22nd, 2022
ENHANCEMENTS AND CHANGES:
  • Disabled caching when using non-Carbon APIs.
BUG FIXES:
  • Fixed a bug whereby the “Low” Security setting was not functioning properly in certain circumstances.

 
2.2.1 - October 19th, 2022
BUG FIXES:
  • Fixed a bug in the volume info cache whereby it wasn’t really collecting information about local volumes. The bug was introduced after the first update to v2.

 
2.2.0 - August 31st, 2022
ENHANCEMENTS AND CHANGES:
  • Added logic to detect certain types of fsEvent database problems associated with
    updating fsEvents on the same volume from different OS versions.

 
2.1.0 - April 27th, 2022
BUG FIXES:
  • Fixed a bug whereby the ‘Low’ ‘Encryption strength’ setting would not accept connections from ChronoSync 10.0.0.

  • Fixed a number of low-level file handling issues.

2.0.0 - March 2nd, 2022
ENHANCEMENTS/MISCELLANEOUS:
  • Apple Silicon Native
    • ChronoAgent v2.0.0 is a Universal binary Application.
  • Updated OpenSSL Library.
CHANGES:
  • Employed new Spotlight disabling strategies.
  • Employed new volume ejection/dismount strategies.
  • Added support for new Archiving features of ChronoSync.
  • Enhanced some diagnostics when copying or moving files.
  • Added real-time monitoring of mounted volume attributes.
  • Fixed various cosmetic issues in the user interface.
  • Improved App Installer.
BUG FIXES:
  • Fixed a bug whereby attempts to suspend Spotlight indexing on a volume was actually
    disabling Spotlight for that volume.
  • If the fsEvents database reports no activity since the reference event, a test file is created
    then deleted on the target volume and fsEvents is queried again. If it still reports no activity, the fsEvent query is reset and designated as such. A log message is generated warning the
    user that there may be a problem.
  • Fixed in-app update problems when invoked from within the System Preference pane.
1.9.9 - February 8th, 2021
BUG FIXES:
  • Fixed a bug that prevented the agent from starting up on some M1 equipped systems.
1.9.8 - September 17th, 2020
ENHANCEMENTS/MISCELLANEOUS:
  • Altered the logic so that sub-second timestamps have to differ by 2ms or more for a file-pair to be considered different when comparing package file contents.
  • Added the ability to construct an APFS volume group w/valid firmlinks on macOS 10.15.5 systems that don’t support manual firmlink creation.

  • Modified Snapshot mount points to now use 0755 permissions.
  • Applied fallback logic to all error conditions that occur when attempting to obtain attributes for an item.
BUG FIXES:
  • Fixed a bug whereby interpreting millisecond timestamps attached to files on APFS filesystems was subject to a scaling error when converting between time representations. This could result in unnecessary file data copying.
  • Fixed an error handling bug when collecting attributes to force a rescan of the directory contents instead of causing an immediate fatal error.
  • Fixed a bug when collecting attributes for directory contents and identifying items that should remain invisible to apps and be ignored.
1.9.7 - February 19th, 2020
ENHANCEMENTS/MISCELLANEOUS:

ENHANCEMENTS/MISCELLANEOUS:
  • Modernized file lock/unlock routines.
BUG FIXES:
  • Fixed a bug whereby obtaining information for the current network interfacecould cause a crash if no information was returned by the OS.

BUG FIXES:
  • Fixed a long-standing bug whereby the results of running external commands and tasks could be misinterpreted because of failing to read the entire output/result from running that command affecting operations such as mounting Disk Images or Blessing bootable backup targets.
  • Fixed a Catalina-specific bug whereby file system observers would fail to detect deep file system changes if the root folder being modified resided on your boot system’s ‘Data’ volume causing live triggered syncs not to run after deep file system changes were made.

BUG FIXES:
  • The preference pane is now displayed in Dark Mode if that UI setting is enabled by the user.

ENHANCEMENTS/MISCELLANEOUS:
  • Now bounces ChronoAgent by completely exiting the program and letting launchd restart it.
  • New logging mechanism including millisecond timestamps, thread ID and threadname (if present).
  • Now sets the maximum concurrent operations to 80 instead of allowing macOS to manage that limit.

  • Fixed a potential bug in the port mapper by preventing premature disposal.
  • Fixed a potential crashing bug in the DDNS IP checker.
    Fixed a potential crashing bug in the DDNS updater.
  • Fixed a bug whereby if the most recent crash log associated with ChronoAgent were deleted, but older crash logs existed, ChronoAgent would report “crash detected” on its nextstartup/bounce.
  • Fixed a bug whereby if reclaiming a child session, the reclaim error message would state “Session dropped/reclaimed by ‘n/a’” because child sessions do not have a host name associated with them.
  • Fixed a bug whereby a Mach port was being leaked every time the ChronoAgentserver obtained a list of network interfaces.
1.9.1 - December 12th, 2018
BUG FIXES:
  • Fixed a bug whereby Finder Tags attached to files were not being decoded into a format that the Finder Tags rule could understand. Thus the rule always failed to detect specific flags.

BUG FIXES:
  • Fixed an incompatibility problem with older versions of ChronoSync.
1.8.1 - April 24th, 2018
ENHANCEMENTS:
  • At the end of the installation, we now ask the user if they would like to open the System Preferences so that they can configure ChronoAgent. This prompt will only occur on initial installation.
  • The Registration panel will now require an e-mail address to be entered.
  • A “New Folder” button is now available when specifying a custom user path for InterConneX clients.
  • Reduced the possibility of seeing the “The specified InterConneX user path is invalid” error message by checking the path multiple times over a fixed time period before giving up and reporting the error.
  • When opening the preference pane, we now impose a brief delay before attempting to resize our panel to fit the main window.
  • If ChronoAgent crashes then ChronoAgent Monitor will now only display a “ChronoAgent Crash Detected” error. Previously, it would display both an “Abnormal Startup” error, as well as a “ChronoAgent Crash Detected” error.
  • If ChronoAgent detects that there is no computer name defined for the system then ChronoAgent Monitor will now display an error, alerting the user to the problem.

  • Updated localizations.
BUG FIXES:
  • Fixed a bug where the ‘Trial’ button would sometimes become enabled when the user was already in Trial mode. Now the button stays disabled while the user is in Trial mode.
  • Fixed some bugs associated with logging session info statistics that are displayed in ChronoAgent Monitor and ChronoMonitor that were associated with sub-channels on open sessions and could result in erroneous connection counts and ‘unknown’ connections being displayed.

BUG FIXES:
  • Fixed a bug whereby the ‘lastCrash’ value of the running summary was not being properly determined.
  • Improved startup by adding logic to recover from slow network services startup.
  • Fixed a potential problem by ensuring we always retrieve the password from preferences instead of using a cached version.
  • Fixed a potential crashing bug in the installer & uninstaller that was due to us over-releasing the display-name string.
1.6.2 - April 27th, 2017
MISCELLANEOUS:
  • Eliminated overzealous authd system log messages triggered by the ChronoAgent Monitor.
