Tampilan baru (mungkin sementara) user guide CodeIgniter 3.0-dev

Setelah versi 2.2.0 rilis tanggal 5 Juni kemarin, saya jadi penasaran pengen nengok repositorinya di github (https://github.com/EllisLab/CodeIgniter). Ternyata untuk versi 3.0 cuma tersisa satu issue lagi, yakni librari Session yang baru. Sudah jadi, tinggal dites untuk recording session ke database pada database selain mysql. Kalo itu udah beres, maka tinggal dirilis deh versi 3 inih. Melihat ini saya jadi cukup yakin sekarang buat pake CodeIgniter versi 3 ini untuk diimplementasikan lebih awal di sistem inti Devository yang sedang kami (tim pengembang Nyankod) selesaikan.

Bicara CI 3, ada banyak sekali peningkatan dan penambahan fitur, plus beberapa perbaikan dari sisi keamanan. Berikut daftar perubahan dari versi 2.2.0 ke versi 3. Memang cukup panjang, tapi saya pribadi seru bacanya. :D

  • Fixed a bug in Zip Library internal method _get_mod_time() where it was not parsing result returned by filemtime().

Versi asli changelog dapat dibaca di user_guide untuk versi 3. Untuk bisa membuka user_guide untuk versi 3 ini, kamu dapat mendownload versi 3-dev dari reponya. Nanti ada folder user_guide_src yang dibuat menggunakan Sphinx documentation. Kalo ada waktu ntar saya bikin postingan tentang cara menginstall Sphinx supaya bisa membaca user_guide CI yang baru.

Selamat datang kembali, CodeIgniter! :D
