v0.5.0: First usable release This release constitutes the first usable release. Some limitations apply, the greatest one probably being that Linux + GCC is the only supported combo thus far (see #51). This release is not considered stable; bookwyrm has now entered the first big bug-squashing stage. All issues listed in #53 and otherwise tagged with v0.6.0 shall be resolved before next minor release. Highlights of this release are: * dropped some dependencies; * replaced termbox with ncurses; * add plugin for Library Genesis; * a lot of wrestling with CPython to bypass segfaults; * implemented downloading of items via libcurl; * TONS of refactoring and general improvements.
