• Changed – Throw an exception when date exceeds the MaxYear value (by @FaithfulDev).
• Fixed – Consider TimeZoneInfo.BaseUtcOffset is a subject to change between years.
• Fixed – Don't include seconds in the ToString method's result when they weren't passed.
• Project – Modernize everything, include testing against the net6.0 target.
• Project – Project files have been updated to enable SourceLink with embedded symbols.
• Project – Enable static analysis via the Microsoft.CodeAnalysis.NetAnalyzers package.

0.7.1

Release Notes

• Fixed – Skipped occurrence in rare cases related to daylight transitions in some time zones on Windows (PR #37 by @aidmsu).

0.7.0

Release Notes

The goal of this release is to make the library native to .NET Standard 2.0 by removing the NETStandard.Library dependency – this will heavily reduce the number of installed packages. There are no new features or bug fixes, so it's more like a maintenance release.

• Added – Explicit netstandard2.0 targeting to not to install any dependencies in .NET Core applications.
• Changed – NETStandard.Library dependency bumped to version 1.6.1 in netstandard1_0 target.
• Changed – Removed the use of .NET's internal AdjustmentRule class because it works differently on Linux with .NET Core 2.X and causes issues.

0.6.3

Release Notes

Important bugs were fixed in this release!

• Fixed – CronExpression.GetOccurrences skip an occurrence when Daylight Saving Time ends (the clocks jump backward).
• Fixed – Sometimes CronExpression.GetOccurrences goes into infinite loop when Daylight Saving Time ends.

0.6.2

Release Notes

• Changed – Decreased memory usage and improved performance of CronExpression.ToString method.
• Fixed – CronExpression.GetNextOccurrence returned wrong result in some cases due to rounding error.

0.6.1

Release Notes

• Added – Implemented ToString method returning cron expression.
• Changed – A link to the project site were added to NuGet package.
• Fixed – Exception message when field value is outside the bounds.

0.6.0

Release Notes

• Added – CronExpression class implemented IEquatable interface. Thus it's possible to compare two instances of CronExpression. They are equal if they define the same date or interval. For example 0,1,2,3 * * * * is equal to 0-3 * * * * but * * L * * is not equal to * * LW * *.
• Added – The GetOccurrences method overloads returning the list of next occurrences within the given date/time range.
• Added – Source link support. If Enable source link support flag is set in Visual Studio it's possible to debug Cronos using its downloaded sources.
• Changed – Relicense Cronos under the MIT License.

0.5.1

Release notes

Added – Supported using days of weeks names with L special character. For example, * * * * SUNL - the last sunday of a month.

0.5.0

Release Notes

• Changed – Denied passing DateTime with DateTimeKind.Local in GetNextOccurrence method. Previous behavior could be incorrect when daylight saving time transitions happened.
• Fixed – CronExpression.Parse became finally case-insensitive. Thus you can use expressions with lowercase special characters: 0 0 lw * *.
• Performance – Decreased the size of the CronExpression by half.
• Performance – Made GetNextOccurrence faster by significant simplification of base algorithm.

0.4.1

Release Notes

Fixed – GetNextOccurrence sometimes returns null when W character is used in DayOfMonth field, from param is on Saturday or Sunday, and next occurrence moves from weekend to the nearest weekday: Monday.
