k8-1.2 (r137)

New functions:

• k8_read_file(): read an entire file as an ArrayBuffer
• k8_decode(): convert an ArrayBuffer/Bytes object to a string
• k8_encode(): convert a string to an ArrayBuffer
• k8_revcomp(): reverse complement a DNA sequence

Improved:

• Bytes.read(): allow to read the rest of a file

k8-1.1 (r129)

This version sets v8's default max_old_space_size to 16 GB and also adds
option -m as a more convenient way to change this parameter.

k8-1.0 (r124)

The previous version of k8, v0.2.5, was built on top of v8-3.16.4 released on
2013-01-11. This version updates v8 to v8-10.2.154.26 released on 2023-01-23,
ten years later. It brings ES6 features including but not limited to the "let"
keyword to define local variables, Java-like classes and back-tick strings.

Due to the lack of the SetIndexedPropertiesToExternalArrayData() API in v8, it
is not possible to keep full backward compatibility with older k8 versions.
Nonetheless, we have tried to retain commonly used methods such that the
several popular k8 scripts can mostly work.

New functions:

• k8_version(): get the k8 version
• Bytes.buffer: get ArrayBuffer

Improved:

• load(): search the script path
• print(): print to stdout. Support ArrayBuffer. Faster for Bytes.
• warn(): print to stderr. Support ArrayBuffer. Faster for Bytes.

Mostly unchanged:

• exit(): exit
• Bytes.length: get/set Bytes length
• Bytes.capacity: get/set Bytes capacity
• new File(): open a file
• File.prototype.close(): close the file handler
• File.prototype.read(): read a byte or bytes
• File.prototype.readline(): read a line
• File.prototype.write(): write to a plain file

Changed functions (BREAKING):

• new Bytes() - Bytes only supports uint8_t now
• Bytes.prototype.set() - Bytes only supports uint8_t

Removed functions (BREAKING):

• Map - JavaScript has Map and works better
• Bytes.prototype.cast() - Bytes only supports uint8_t
• Bytes[] - not possible to implement. Use Bytes.buffer as a partial remedy

(1.0: 10 August 2023, r124)

k8-0.2.5 (r80)

Fixed a bug in readline that reads an empty line when the file size is a multiple of 65536. This is the same bug in klib/kseq.h.

K8-0.2.4 (r79)

For shell compatibility, skip the first line if it starts with #!.

k8-0.2.3

• Set default --max_old_space_size to 16384
• Allow to change --max_old_space_size also with option -M, which is shorter
• Updated instructions on compiling k8, as gyp svn is offline now

k8-0.2.2

Added the "Map" object for populating huge hash tables.

k8-0.2.1

Release k8-0.2.1
