htmltools 0.3.6

• validateCssUnit() now accepts viewport units (vw, vh, vmin, vmax). (#56)

• restorePreserveChunks() marks the output with the correct encoding now (UTF-8).

• Length-0 attributes are now dropped, like NULLs. (#65)

• Fixed #69: On Windows, renderDocument() did not mark output as UTF-8 if the head was UTF-8 but body was ASCII. (#71)

htmltools 0.3.5

• as.character now returns a character vector with no other attributes. Previously it returned a character vector of class 'html'. (#31, #41)

• htmlTemplate now can use a string as a template instead of requiring a file. (#41, #43)

• HTML dependencies can now be added inline, instead of needing to use attachDependencies(). (#40, #42)

• htmlDependency() gained a new argument all_files to indicate whether all files under the src directory should be copied when rendering dependencies, or only those specified in the dependency objects. (#48)

• copyDependencyToDir() will always completely overwrite the target directory when copying HTML dependency files to make sure all dependency files are definitely updated in the target directory when the original dependency directory has been updated. In the past, the dependency files were not updated if they already existed. (#36)

• The version number in the directory name of an HTML dependency can be suppressed by setting options(htmltools.dir.version = FALSE) when the dependency is copied via copyDependencyToDir(). (#37)

• Performance improvement rendering tags, by switching from readLines to readChar.

htmltools 0.2.9

• Add check that htmlDependency() isn't called with an absolute path when a binary package is built. (#22)
